1 00:00:04,240 --> 00:00:07,240 Speaker 1: Welcome to tech Stuff, a production of I Heart Radios 2 00:00:07,320 --> 00:00:14,080 Speaker 1: How Stuff Works. Hey there, and welcome to tech Stuff. 3 00:00:14,120 --> 00:00:17,239 Speaker 1: I'm your host, Jonathan Strickland, and I'm an executive producer 4 00:00:17,239 --> 00:00:20,239 Speaker 1: with I Heart Radio and I love all things tech 5 00:00:20,800 --> 00:00:24,279 Speaker 1: and today's episode is a special one. So for one thing, 6 00:00:24,560 --> 00:00:27,680 Speaker 1: you're going to get to hear that intro all over 7 00:00:27,800 --> 00:00:31,600 Speaker 1: again in just a second, because this episode is brought 8 00:00:31,640 --> 00:00:34,519 Speaker 1: to you by Mazda. The company invited me to come 9 00:00:34,560 --> 00:00:37,479 Speaker 1: out to the Los Angeles Auto Show in November two 10 00:00:37,520 --> 00:00:40,879 Speaker 1: thousand nineteen to check out their cars and specifically to 11 00:00:40,920 --> 00:00:43,880 Speaker 1: get some hands on time with the c X thirty suv, 12 00:00:44,400 --> 00:00:47,559 Speaker 1: and that included the chance to record an episode on 13 00:00:47,640 --> 00:00:51,520 Speaker 1: the show floor inside a c X thirty. And I 14 00:00:51,560 --> 00:00:55,600 Speaker 1: was talking about the concept of human centric design, specifically 15 00:00:55,800 --> 00:00:59,280 Speaker 1: within the context of designing vehicles and even more specifically 16 00:00:59,320 --> 00:01:01,760 Speaker 1: the c X there. So what you're about to hear 17 00:01:02,000 --> 00:01:04,959 Speaker 1: is the audio from that. It was recorded on Friday, 18 00:01:05,040 --> 00:01:08,160 Speaker 1: November twenty second, two thousand nineteen, from the Mazda booth 19 00:01:08,200 --> 00:01:11,080 Speaker 1: at the l A Auto Show. You will also hear 20 00:01:11,200 --> 00:01:14,959 Speaker 1: some audio from a separate conversation with Dave Coleman, who's 21 00:01:14,959 --> 00:01:18,880 Speaker 1: an engineer at Mazda. He's with their research and development division, 22 00:01:19,360 --> 00:01:21,760 Speaker 1: and he talks in more detail about the kinds of 23 00:01:21,760 --> 00:01:25,319 Speaker 1: decisions that go into creating a specific experience, which is 24 00:01:25,360 --> 00:01:28,200 Speaker 1: kind of at the heart of the philosophy of human 25 00:01:28,360 --> 00:01:31,039 Speaker 1: centric design. There are a couple of other notes I 26 00:01:31,040 --> 00:01:34,800 Speaker 1: want to mention before we jump into this. First is 27 00:01:34,840 --> 00:01:37,920 Speaker 1: that this episode was recorded live in the Los Angeles 28 00:01:38,000 --> 00:01:41,800 Speaker 1: Convention Center, and so it's not going to sound like 29 00:01:42,040 --> 00:01:46,520 Speaker 1: the studio recordings. You'll likely hear a lot of extraneous sounds. 30 00:01:46,880 --> 00:01:49,960 Speaker 1: I even comment on it at one point. Another is 31 00:01:50,000 --> 00:01:53,080 Speaker 1: that you may hear some other familiar voices when we 32 00:01:53,080 --> 00:01:56,800 Speaker 1: get to Dave's discussions because Lauren voege Obama Brain Stuff, 33 00:01:56,920 --> 00:02:00,240 Speaker 1: and and savor Uh and Jack O'Brien and Miles of 34 00:02:00,240 --> 00:02:03,960 Speaker 1: the Daily Zeitgeist we're also there at the show, so 35 00:02:04,160 --> 00:02:07,200 Speaker 1: they are occasionally chatting as well. You might hear their voices, 36 00:02:07,560 --> 00:02:10,399 Speaker 1: and I will be popping in from the studio as 37 00:02:10,400 --> 00:02:13,919 Speaker 1: in from where I'm recording right now a few times 38 00:02:13,919 --> 00:02:16,720 Speaker 1: to help kind of bridge a few gaps between Dave's 39 00:02:16,720 --> 00:02:20,359 Speaker 1: discussions and the episode I recorded. So with all that 40 00:02:20,560 --> 00:02:24,280 Speaker 1: business out of the way, let's hear that intro all 41 00:02:24,400 --> 00:02:28,639 Speaker 1: over again, So take it away past Jonathan. Hey there, 42 00:02:28,680 --> 00:02:32,400 Speaker 1: and welcome to text stuff. I'm your host, Jonathan Strickland. 43 00:02:32,480 --> 00:02:34,800 Speaker 1: I'm an executive producer with my Heart Radio and I 44 00:02:35,200 --> 00:02:39,400 Speaker 1: love all things tech and ladies and gentlemen. I am 45 00:02:39,520 --> 00:02:43,000 Speaker 1: having quite the experience right now. I know a lot 46 00:02:43,080 --> 00:02:45,600 Speaker 1: of you listeners out there. You like to listen to 47 00:02:45,639 --> 00:02:48,320 Speaker 1: me while you're in your car. Well, guess what. I'm 48 00:02:48,360 --> 00:02:52,079 Speaker 1: recording this from inside a Mazda c X thirty at 49 00:02:52,120 --> 00:02:54,880 Speaker 1: the l A Auto Show. Yeah. For once, I'm talking 50 00:02:54,919 --> 00:02:58,359 Speaker 1: to you in a car. Let's just let's just hang 51 00:02:58,400 --> 00:03:02,160 Speaker 1: out together for a while, shall we. So today I 52 00:03:02,280 --> 00:03:06,760 Speaker 1: have the incredible opportunity to talk about the philosophy behind 53 00:03:06,960 --> 00:03:13,520 Speaker 1: human centric design. This is something I've always been fascinated by. 54 00:03:13,960 --> 00:03:17,919 Speaker 1: It's something that applies to all elements of design, no 55 00:03:17,960 --> 00:03:21,800 Speaker 1: matter what you are trying to create. But I'm specifically 56 00:03:21,800 --> 00:03:24,320 Speaker 1: going to talk about it in the context of the 57 00:03:24,320 --> 00:03:27,320 Speaker 1: Masda c X thirty because I happen to be sitting 58 00:03:27,440 --> 00:03:30,520 Speaker 1: in the front seat of one, and it is also comfortable. 59 00:03:30,600 --> 00:03:32,960 Speaker 1: This is actually tri I don't know where you are 60 00:03:33,040 --> 00:03:35,600 Speaker 1: right now, but this seat is really good. So if 61 00:03:35,640 --> 00:03:37,480 Speaker 1: you can talk to Mazda and find out how to 62 00:03:37,680 --> 00:03:39,800 Speaker 1: get the seat in the studio to be just like 63 00:03:39,880 --> 00:03:43,520 Speaker 1: this one. That's great, and if you don't, you're fired. Okay, 64 00:03:43,560 --> 00:03:48,440 Speaker 1: So I want to talk about the general principles behind 65 00:03:48,440 --> 00:03:50,680 Speaker 1: design in the first place, and then we'll narrow it down. 66 00:03:50,720 --> 00:03:54,360 Speaker 1: You guys know how my show goes. So let's say 67 00:03:54,360 --> 00:03:59,280 Speaker 1: you're an engineer and you have defined what goal you're 68 00:03:59,320 --> 00:04:04,080 Speaker 1: going for. You've identified a specific goal that you want 69 00:04:04,120 --> 00:04:08,480 Speaker 1: to achieve. And beyond defining the goal, that's obviously one 70 00:04:08,480 --> 00:04:12,200 Speaker 1: of the first big parts of this process. You need 71 00:04:12,240 --> 00:04:14,120 Speaker 1: to figure out what are your objectives and what are 72 00:04:14,160 --> 00:04:17,680 Speaker 1: your challenges, what are the things standing in your way 73 00:04:17,720 --> 00:04:21,280 Speaker 1: of achieving your goal, and you start to make decisions 74 00:04:21,560 --> 00:04:24,800 Speaker 1: to try and get to your goal as best you can. 75 00:04:25,480 --> 00:04:29,800 Speaker 1: Those decisions can sometimes end up having things that conflict 76 00:04:29,839 --> 00:04:31,279 Speaker 1: with each other. You have to find a way to 77 00:04:31,360 --> 00:04:36,800 Speaker 1: resolve those conflicts and to actually achieve the goal you 78 00:04:36,839 --> 00:04:40,640 Speaker 1: have defined for yourself. This is not necessarily an easy 79 00:04:40,640 --> 00:04:42,680 Speaker 1: thing to do. It's one of the biggest challenges of engineering. 80 00:04:42,680 --> 00:04:44,760 Speaker 1: It's why a lot of the engineers I've talked to 81 00:04:45,360 --> 00:04:49,520 Speaker 1: relish their job. They love the process of sitting down 82 00:04:50,080 --> 00:04:54,800 Speaker 1: and going from concept to reality and all the processes 83 00:04:54,960 --> 00:04:57,440 Speaker 1: that go along with that. Now, some of that can 84 00:04:57,520 --> 00:04:59,200 Speaker 1: end up being a lot of trial and error. A 85 00:04:59,200 --> 00:05:01,359 Speaker 1: lot of it can end up being having to to 86 00:05:01,440 --> 00:05:04,760 Speaker 1: retrace your steps, and if we're all being honest, not 87 00:05:04,920 --> 00:05:08,840 Speaker 1: all of it is super fun. Sometimes you try out 88 00:05:08,880 --> 00:05:11,440 Speaker 1: an idea that you were convinced was going to be 89 00:05:11,480 --> 00:05:13,880 Speaker 1: perfect and then you realize that, oh, you know what, 90 00:05:13,960 --> 00:05:17,000 Speaker 1: it's good, but it just broke everything else. So it's 91 00:05:17,000 --> 00:05:21,040 Speaker 1: a very tough process to actually go through. But once 92 00:05:21,080 --> 00:05:24,200 Speaker 1: you have figured out all the different challenges, you defined 93 00:05:24,240 --> 00:05:27,679 Speaker 1: your objectives, you start to ideate your solutions. You start 94 00:05:27,720 --> 00:05:30,680 Speaker 1: to think, this is the way I think is the 95 00:05:30,720 --> 00:05:33,720 Speaker 1: best for me to achieve the goal, and then how 96 00:05:33,720 --> 00:05:36,320 Speaker 1: do I go about actually making that reality. You go 97 00:05:36,400 --> 00:05:40,000 Speaker 1: through that process, which can be laborious, and then you 98 00:05:40,040 --> 00:05:42,159 Speaker 1: test it and you find out how well you did, 99 00:05:42,520 --> 00:05:46,440 Speaker 1: and maybe it turns out that the solution you have 100 00:05:47,240 --> 00:05:51,200 Speaker 1: is incredible on paper, but in reality it turns out 101 00:05:51,240 --> 00:05:53,960 Speaker 1: to fall short. That's something that actually does happen quite 102 00:05:53,960 --> 00:05:57,799 Speaker 1: a bit in all realms of technology, and I've seen 103 00:05:57,880 --> 00:06:02,480 Speaker 1: this a lot in my uh storied career as a 104 00:06:02,480 --> 00:06:07,400 Speaker 1: technology journalist. You see attempts to try and achieve something 105 00:06:07,480 --> 00:06:11,400 Speaker 1: really revolutionary, let's say, and in the process you might 106 00:06:11,560 --> 00:06:14,599 Speaker 1: end up losing sight of what your initial goal was 107 00:06:14,600 --> 00:06:16,840 Speaker 1: in the first place, which was to deliver something to 108 00:06:17,480 --> 00:06:21,440 Speaker 1: an end user, whoever that may be, that is meaningful 109 00:06:21,600 --> 00:06:25,480 Speaker 1: and and produces a specific result. Maybe that the thing 110 00:06:25,520 --> 00:06:29,400 Speaker 1: you've created works really well again on paper, but that 111 00:06:29,520 --> 00:06:32,880 Speaker 1: it doesn't feel like it works really well when you 112 00:06:32,880 --> 00:06:36,000 Speaker 1: get it in the hands of the end user. That 113 00:06:36,160 --> 00:06:39,719 Speaker 1: is what human centric design tries to address. It tries 114 00:06:39,760 --> 00:06:43,360 Speaker 1: to keep in mind that at the end of the day, 115 00:06:43,680 --> 00:06:47,480 Speaker 1: you are making something to create a human experience, and 116 00:06:47,520 --> 00:06:52,160 Speaker 1: that every decision you make ultimately needs to be geared 117 00:06:52,279 --> 00:06:55,160 Speaker 1: toward that. Also, I'm probably gonna be dropping a lot 118 00:06:55,160 --> 00:06:59,479 Speaker 1: of car puns unintentionally. It's just because I'm in this environment. 119 00:07:00,240 --> 00:07:05,840 Speaker 1: So we've talked about that little element of challenge, this 120 00:07:05,920 --> 00:07:08,800 Speaker 1: idea of trying to, you know, I, identify what your 121 00:07:08,800 --> 00:07:11,400 Speaker 1: goal is and to work your way to it. The 122 00:07:11,480 --> 00:07:14,000 Speaker 1: next thing you have to think about is how your 123 00:07:14,040 --> 00:07:18,360 Speaker 1: goal may end up working with, integrating with other goals 124 00:07:18,440 --> 00:07:22,560 Speaker 1: that other people have, or it may conflict with those Because, 125 00:07:23,000 --> 00:07:26,320 Speaker 1: as I'm sure you're all aware, something like a car, 126 00:07:26,560 --> 00:07:32,240 Speaker 1: a vehicle. Uh, it's actually a collection of many different systems. Now, 127 00:07:32,280 --> 00:07:36,440 Speaker 1: each system needs to contribute toward that end goal, that 128 00:07:36,560 --> 00:07:40,680 Speaker 1: human centric goal where you're creating this feeling that you 129 00:07:40,720 --> 00:07:45,560 Speaker 1: want your end user to have. But they don't necessarily 130 00:07:45,600 --> 00:07:51,560 Speaker 1: all work in harmony together natively. You can't expect that 131 00:07:51,680 --> 00:07:54,720 Speaker 1: if you're working, let's say, on a drive train system 132 00:07:54,800 --> 00:07:57,520 Speaker 1: and someone else is working on a different system, that 133 00:07:57,560 --> 00:08:00,360 Speaker 1: those two are just going to magically work together and 134 00:08:00,480 --> 00:08:03,800 Speaker 1: produce the perfect experience when it all comes out at 135 00:08:03,840 --> 00:08:06,520 Speaker 1: the end. You actually have to do a lot of collaboration, 136 00:08:06,920 --> 00:08:09,840 Speaker 1: and sometimes that means that you're having lots of complicated 137 00:08:09,880 --> 00:08:14,920 Speaker 1: conversations weighing your different goals, weighing your different priorities, and 138 00:08:15,000 --> 00:08:19,000 Speaker 1: deciding which ones are going to take priority in one 139 00:08:19,000 --> 00:08:21,960 Speaker 1: case versus another. You might be able to make some concessions. 140 00:08:22,040 --> 00:08:24,400 Speaker 1: You might be able to kind of find a middle ground. 141 00:08:24,400 --> 00:08:27,559 Speaker 1: You might be able to find use cases where one 142 00:08:27,760 --> 00:08:32,200 Speaker 1: philosophy wins out over another. For example, we had a 143 00:08:32,280 --> 00:08:35,920 Speaker 1: chance to talk with a great engineer, Dave. He talked 144 00:08:35,960 --> 00:08:39,360 Speaker 1: about how with the Masta c X thirty, there was 145 00:08:39,440 --> 00:08:43,120 Speaker 1: this balance between performance and making sure that the ride 146 00:08:43,160 --> 00:08:46,319 Speaker 1: was nice and quiet. And the problem is that as 147 00:08:46,360 --> 00:08:50,040 Speaker 1: you start to weigh one of those, the other one 148 00:08:50,240 --> 00:08:54,920 Speaker 1: begins begins to uh end up having needing more attention. 149 00:08:55,640 --> 00:08:57,880 Speaker 1: So you have to figure out, well, where's the balance here. 150 00:08:57,920 --> 00:08:59,920 Speaker 1: We want to make sure that we have all the 151 00:09:00,040 --> 00:09:02,640 Speaker 1: elements here so that we create the feeling that we 152 00:09:02,679 --> 00:09:06,520 Speaker 1: really want our end users to have. And that is 153 00:09:06,559 --> 00:09:09,840 Speaker 1: not something again that is natively obvious. It means that 154 00:09:09,920 --> 00:09:13,520 Speaker 1: you have to have a lot of conversations, a lot 155 00:09:13,559 --> 00:09:17,839 Speaker 1: of collaboration. Uh. And in the case of Mazda, as 156 00:09:17,880 --> 00:09:20,120 Speaker 1: we learned while we were here at the auto show, 157 00:09:20,720 --> 00:09:23,920 Speaker 1: that ends up being a lot easier because the teams 158 00:09:24,120 --> 00:09:29,320 Speaker 1: are more closely located to one another. They aren't spread 159 00:09:29,400 --> 00:09:32,720 Speaker 1: across the globe where you might have one team working 160 00:09:32,760 --> 00:09:35,440 Speaker 1: completely independently of the others. And then when you bring 161 00:09:35,480 --> 00:09:38,000 Speaker 1: all the systems together, only then do you realize that 162 00:09:38,080 --> 00:09:41,679 Speaker 1: you start seeing these conflicts. Hey, it's Jonathan from the 163 00:09:41,720 --> 00:09:44,440 Speaker 1: booth again. But I just wanted to tell you that 164 00:09:44,480 --> 00:09:46,640 Speaker 1: we're going to take a very quick break and come 165 00:09:46,800 --> 00:09:56,960 Speaker 1: right back to the episode, So don't go anywhere, all right, guys, 166 00:09:56,960 --> 00:09:59,120 Speaker 1: it's Jonathan from the studio again. Now I figured This 167 00:09:59,200 --> 00:10:01,640 Speaker 1: is a great spot to insert some audio that we 168 00:10:01,760 --> 00:10:05,640 Speaker 1: captured with Engineered Dave Coleman that really helps illustrate what 169 00:10:05,760 --> 00:10:09,959 Speaker 1: I was talking about earlier on. In this episode, we're 170 00:10:09,960 --> 00:10:12,080 Speaker 1: going to start with Dave giving us the sort of 171 00:10:12,400 --> 00:10:15,000 Speaker 1: mission statement his team had in mind and how they 172 00:10:15,000 --> 00:10:18,080 Speaker 1: went about trying to achieve it. So I guess at 173 00:10:18,200 --> 00:10:21,000 Speaker 1: a high level, what we're trying to do with this 174 00:10:21,120 --> 00:10:25,480 Speaker 1: car is gets something that is we'll let you do 175 00:10:25,559 --> 00:10:27,160 Speaker 1: kind of just whatever it you want to do, wherever 176 00:10:27,200 --> 00:10:29,760 Speaker 1: you want to go whatever. It's not really specifically tune 177 00:10:29,800 --> 00:10:32,880 Speaker 1: to one particular kind of driving. UM. It's supposed to 178 00:10:32,880 --> 00:10:36,000 Speaker 1: be really sort of natural and easy and capable enough 179 00:10:36,040 --> 00:10:39,680 Speaker 1: to to do whatever hurt you're interested in. UM. So 180 00:10:39,920 --> 00:10:42,800 Speaker 1: we wanted to make it so it's it's comfortable and 181 00:10:42,880 --> 00:10:45,839 Speaker 1: quiet every day, it's efficient, it's fun to drive. When 182 00:10:45,840 --> 00:10:48,440 Speaker 1: you go out on twisty road and you want to 183 00:10:48,480 --> 00:10:51,640 Speaker 1: go to some you know, rock climbing place or hiking 184 00:10:51,640 --> 00:10:53,760 Speaker 1: trail and mountain bike and that's way up some dirt 185 00:10:53,840 --> 00:10:56,520 Speaker 1: road that's really tricky. It's got to off road capability 186 00:10:56,640 --> 00:10:59,960 Speaker 1: to get you there too, and it's balancing all the 187 00:11:00,320 --> 00:11:03,280 Speaker 1: kind of the right way is a big trick. Um. 188 00:11:03,400 --> 00:11:05,800 Speaker 1: We're we've been working on some new sort of off 189 00:11:05,880 --> 00:11:09,960 Speaker 1: road capabilities. It's mostly electronic trickery. UM, and sort of 190 00:11:10,000 --> 00:11:11,839 Speaker 1: had to figure out where we draw the line on 191 00:11:12,120 --> 00:11:15,080 Speaker 1: making our cars taple on offer. We've always been a 192 00:11:15,120 --> 00:11:18,839 Speaker 1: completely on road company. Uh, and so we've we've sort 193 00:11:18,840 --> 00:11:21,680 Speaker 1: of drawn the line that, uh, well, there's a lot 194 00:11:21,720 --> 00:11:23,440 Speaker 1: of stuff you can do to make cars super capable 195 00:11:23,679 --> 00:11:26,000 Speaker 1: offer road that ruins how it drives the rest of 196 00:11:26,040 --> 00:11:28,720 Speaker 1: the time. So we've drawn the line that we won't 197 00:11:28,760 --> 00:11:30,439 Speaker 1: do anything to compromise how it drives on the road, 198 00:11:31,000 --> 00:11:34,480 Speaker 1: but we still want all the capabilities to get places. Um. 199 00:11:34,679 --> 00:11:37,160 Speaker 1: And this is the first car that we've got that's 200 00:11:37,160 --> 00:11:41,880 Speaker 1: got an offer button that changes a bunch of the settings. UM. 201 00:11:41,880 --> 00:11:44,440 Speaker 1: So some of the some of the kind of trick 202 00:11:45,320 --> 00:11:49,720 Speaker 1: stuff that we're doing under the skin. UM. We've got 203 00:11:49,760 --> 00:11:52,200 Speaker 1: our new all the drive system and the G Vectorian 204 00:11:52,200 --> 00:11:55,720 Speaker 1: control system, which is a very weird, subtle thing for 205 00:11:56,120 --> 00:11:58,920 Speaker 1: making the car behave in a way that feels more 206 00:11:59,000 --> 00:12:03,680 Speaker 1: natural to people. UM. So we've I'll start with the 207 00:12:03,679 --> 00:12:07,400 Speaker 1: G factor in control. So, UM, we found that as 208 00:12:07,400 --> 00:12:10,960 Speaker 1: you're driving, the very first moment you make the steering 209 00:12:10,960 --> 00:12:13,319 Speaker 1: input The cars are a little bit Every car is 210 00:12:13,320 --> 00:12:15,040 Speaker 1: a little bit inconsistent about how it makes that first 211 00:12:15,080 --> 00:12:16,839 Speaker 1: bit of the turn. And the reason is because you're 212 00:12:16,840 --> 00:12:21,400 Speaker 1: sitting on these theneumatic tires. It's just a balloon, right Uh. 213 00:12:21,440 --> 00:12:25,199 Speaker 1: And in its straight ahead state, both sidewalls are sort 214 00:12:25,200 --> 00:12:29,120 Speaker 1: of unloaded, and when you corner, one of sidewall goes 215 00:12:29,160 --> 00:12:31,400 Speaker 1: slack and one starts pulling, and that's what's pulling the 216 00:12:31,440 --> 00:12:33,720 Speaker 1: car in the corners. So there's this transition period as 217 00:12:33,760 --> 00:12:37,600 Speaker 1: the car starts to transition into that corner, and that's 218 00:12:37,640 --> 00:12:40,640 Speaker 1: where things are kind of the most nervous for the 219 00:12:40,720 --> 00:12:42,800 Speaker 1: driver's subconscious as they kind of DESI will when do 220 00:12:42,880 --> 00:12:44,920 Speaker 1: I turn and how much do I turn? And once 221 00:12:44,920 --> 00:12:46,880 Speaker 1: you get into the corner and everything feels naturally, you 222 00:12:47,120 --> 00:12:50,920 Speaker 1: figure out what you're doing. But people aren't really consciously nervous. 223 00:12:51,000 --> 00:12:53,200 Speaker 1: But if you watch someone's steering inputs as they turn 224 00:12:53,240 --> 00:12:55,280 Speaker 1: into a corner, a lot of times they turn in 225 00:12:55,280 --> 00:12:57,280 Speaker 1: and back off and adjust a couple of times because 226 00:12:57,320 --> 00:13:00,439 Speaker 1: they get it figured out. Uh. And so designed the 227 00:13:00,480 --> 00:13:04,560 Speaker 1: system to try to attack that subtle problem that people 228 00:13:04,600 --> 00:13:08,319 Speaker 1: didn't know they were doing. Um. And what we do 229 00:13:08,559 --> 00:13:10,439 Speaker 1: is we figured out that we can we can wait, 230 00:13:10,960 --> 00:13:12,720 Speaker 1: but a little bit more weight on the front tires 231 00:13:12,760 --> 00:13:15,280 Speaker 1: just as you turn. Uh. And this is a trick 232 00:13:15,360 --> 00:13:19,040 Speaker 1: that we learned from race driving. Um I used to 233 00:13:19,080 --> 00:13:22,280 Speaker 1: race rally cars racing off road in the gravel, and 234 00:13:22,679 --> 00:13:24,960 Speaker 1: the rally drivers always using the left foot on the brakes. 235 00:13:25,200 --> 00:13:26,480 Speaker 1: You turn the wheel and put a little bit of 236 00:13:26,800 --> 00:13:28,640 Speaker 1: extra weight on the front tires and it makes them 237 00:13:28,679 --> 00:13:31,600 Speaker 1: grab into the into the grab or turn the car. UM. 238 00:13:31,640 --> 00:13:33,280 Speaker 1: A lot of broad racing guys will do this to 239 00:13:33,360 --> 00:13:34,840 Speaker 1: one foot on the gas, one foot on the brake, 240 00:13:35,080 --> 00:13:36,880 Speaker 1: unlike on the street where you're left foots on the 241 00:13:36,880 --> 00:13:39,920 Speaker 1: clutch or just resting. But you've got one on each 242 00:13:39,920 --> 00:13:42,440 Speaker 1: of you can you can constantly adjust the weight balance 243 00:13:42,440 --> 00:13:44,760 Speaker 1: of the car. So we started sort of from that 244 00:13:44,960 --> 00:13:47,600 Speaker 1: idea and tuned it and tuned it and tuned it, 245 00:13:48,600 --> 00:13:50,680 Speaker 1: trying to make it so it's so subtle. You don't 246 00:13:50,760 --> 00:13:53,680 Speaker 1: feel the car slowing down to shift weight under the front, 247 00:13:53,760 --> 00:13:55,800 Speaker 1: but you do feel the response in the way the 248 00:13:55,840 --> 00:14:01,679 Speaker 1: car turns. Um And now we've got a tune. So 249 00:14:01,960 --> 00:14:04,040 Speaker 1: there's steering system. As you turn the wheel, the electric 250 00:14:04,040 --> 00:14:07,000 Speaker 1: power steering knows exactly what the put you're giving it, 251 00:14:07,160 --> 00:14:10,119 Speaker 1: so it looks at the steering speed and that communicates 252 00:14:10,120 --> 00:14:11,880 Speaker 1: with the engine computer and it tells it to reduce 253 00:14:11,920 --> 00:14:15,280 Speaker 1: power just a hair and it dips a little bit 254 00:14:15,280 --> 00:14:17,120 Speaker 1: of extra weight onto the front tires and tightens up 255 00:14:17,160 --> 00:14:21,760 Speaker 1: the tires so they respond more directly. Um, we don't 256 00:14:21,760 --> 00:14:24,280 Speaker 1: have any on off switch for that. They'll never feel it. 257 00:14:24,000 --> 00:14:25,840 Speaker 1: It's it's soon so well that it just kind of 258 00:14:25,920 --> 00:14:28,960 Speaker 1: just feels normal all the time. Right. We've built a 259 00:14:28,960 --> 00:14:31,440 Speaker 1: couple of cars with on off switches for that, and 260 00:14:31,480 --> 00:14:34,800 Speaker 1: it's it's really funny because it's it's it's not super obvious, 261 00:14:35,440 --> 00:14:38,120 Speaker 1: but it's once you kind of pick out what it's doing, 262 00:14:38,600 --> 00:14:41,240 Speaker 1: it actually makes a difference even just driving completely straight ahead, 263 00:14:41,520 --> 00:14:44,040 Speaker 1: because you don't realize is when you're driving straight you're 264 00:14:44,040 --> 00:14:46,960 Speaker 1: making constantly making little corrections, right, and if each one 265 00:14:47,000 --> 00:14:48,640 Speaker 1: of those has a little delay, and then to catch up, 266 00:14:48,680 --> 00:14:51,720 Speaker 1: you're you're constantly overshooting and coming back. And as soon 267 00:14:51,760 --> 00:14:54,440 Speaker 1: as we turn the system on, people just just settle 268 00:14:54,520 --> 00:14:56,960 Speaker 1: up because they make repression and would stick and they 269 00:14:57,000 --> 00:14:58,360 Speaker 1: wouldn't have to make the next one of the next 270 00:14:58,360 --> 00:15:02,280 Speaker 1: one and the next one. Um. So that's in all 271 00:15:02,280 --> 00:15:06,400 Speaker 1: of our cars now. Um that that's called g Vactric control. 272 00:15:06,440 --> 00:15:09,640 Speaker 1: We just came out with the electric control plus which 273 00:15:09,920 --> 00:15:13,360 Speaker 1: helps when you start straighten the wheel back out, um, 274 00:15:13,440 --> 00:15:17,080 Speaker 1: and the the car will sometimes be a little bit 275 00:15:17,120 --> 00:15:18,920 Speaker 1: slow to kind of come backing up the pull wheel 276 00:15:18,920 --> 00:15:21,680 Speaker 1: straight and so to avoid that, we actually will drag 277 00:15:21,760 --> 00:15:24,600 Speaker 1: the outside break just a hair and it suddenly just 278 00:15:24,680 --> 00:15:26,960 Speaker 1: kind of kind of helps it straight back out. You 279 00:15:26,960 --> 00:15:29,040 Speaker 1: don't again, you don't feel a break when you can 280 00:15:29,040 --> 00:15:30,840 Speaker 1: switch it on and off. What you feel is it 281 00:15:30,920 --> 00:15:33,080 Speaker 1: feels soally normal. And then if if you were to 282 00:15:33,120 --> 00:15:35,800 Speaker 1: switch the system off, you feel like steerings kind of 283 00:15:35,800 --> 00:15:37,800 Speaker 1: going yeah, gun, yeah, gun's a good but yeah, it's 284 00:15:37,800 --> 00:15:39,240 Speaker 1: just kind of overdamped and you kind of have to 285 00:15:39,280 --> 00:15:43,000 Speaker 1: pull it back. Um. So we're really kind of down 286 00:15:43,000 --> 00:15:45,320 Speaker 1: in the weeds of these little subtle details to get 287 00:15:45,360 --> 00:15:49,120 Speaker 1: the car to feel natural and to feel totally almost 288 00:15:49,120 --> 00:15:50,680 Speaker 1: so you don't notice all the work we did, right. 289 00:15:52,240 --> 00:15:55,680 Speaker 1: Is there like a general like description drivers have that 290 00:15:56,040 --> 00:15:58,120 Speaker 1: like now that this stuff has been corrected, or do 291 00:15:58,240 --> 00:16:03,120 Speaker 1: they just like say it's smoother, like you know, we've 292 00:16:03,160 --> 00:16:06,200 Speaker 1: always had a focus on this kind of area. Um, 293 00:16:06,480 --> 00:16:09,120 Speaker 1: so we've always sort of tuned our cars to feel 294 00:16:09,240 --> 00:16:11,120 Speaker 1: just feel right and just feel until it used to 295 00:16:11,160 --> 00:16:13,680 Speaker 1: be our slogan decades ago. It just feels right right. 296 00:16:13,720 --> 00:16:15,760 Speaker 1: That's It's we've kind of always been trying to do 297 00:16:15,800 --> 00:16:20,400 Speaker 1: the same thing. Um. So I don't think adding GBC 298 00:16:20,640 --> 00:16:23,280 Speaker 1: wasn't like a dramatic change. Was another tool in our 299 00:16:23,320 --> 00:16:25,040 Speaker 1: toolbox of all these things that we're trying to do. 300 00:16:25,160 --> 00:16:26,600 Speaker 1: If we took this system and put it on the 301 00:16:26,600 --> 00:16:28,800 Speaker 1: car built by people who didn't care about this stuff, 302 00:16:28,800 --> 00:16:31,280 Speaker 1: it wouldn't be enough to pick it right, but it's 303 00:16:31,360 --> 00:16:34,120 Speaker 1: enough to sort of add in our direction of making 304 00:16:34,120 --> 00:16:39,400 Speaker 1: the car, you know, more natural. Um. Sort of our 305 00:16:39,480 --> 00:16:42,400 Speaker 1: our ind goal is to make driving a car so 306 00:16:43,400 --> 00:16:45,840 Speaker 1: naturally you don't think about it. You're just you just drive, 307 00:16:46,040 --> 00:16:49,080 Speaker 1: just do exactly what you wanted to do. Um. The 308 00:16:49,080 --> 00:16:54,160 Speaker 1: whole wheel drive system in this car we mechanically is 309 00:16:54,200 --> 00:16:56,640 Speaker 1: the same as almost everybody's. You drive the front wheels, 310 00:16:56,880 --> 00:16:58,720 Speaker 1: there's a clutch where you can connect the rear wheels 311 00:16:58,800 --> 00:17:01,440 Speaker 1: sometimes when you need it and not when you don't. 312 00:17:01,880 --> 00:17:03,800 Speaker 1: And all the magic is in the software to figure 313 00:17:03,800 --> 00:17:06,479 Speaker 1: out when you need it when you don't exactly how much, right, 314 00:17:06,520 --> 00:17:09,000 Speaker 1: because if you're always driving the rear wheels, it uses 315 00:17:09,000 --> 00:17:12,159 Speaker 1: a lot of extra fuel and it actually UM diffront 316 00:17:12,200 --> 00:17:13,680 Speaker 1: reules have to go to the same speed when they're 317 00:17:13,720 --> 00:17:15,600 Speaker 1: locked together, and so the car doesn't want to turn, 318 00:17:16,600 --> 00:17:18,880 Speaker 1: and so you're always balancing its ability to turn with 319 00:17:18,920 --> 00:17:23,400 Speaker 1: its ability to drive the rear wheels. UM. We've come 320 00:17:23,440 --> 00:17:26,680 Speaker 1: up with a system where we're running software algorithm that's 321 00:17:26,720 --> 00:17:29,440 Speaker 1: basically kind of like a video game algorithm that's looking 322 00:17:29,480 --> 00:17:33,400 Speaker 1: at the vehicle speed and cornering G acceleration G hand 323 00:17:33,400 --> 00:17:35,760 Speaker 1: calculating exactly how much loaders on each tire based on 324 00:17:35,800 --> 00:17:39,280 Speaker 1: the vehicle dynamics model of how this car behaves. And 325 00:17:39,320 --> 00:17:43,040 Speaker 1: so it's constantly calculating what load is on each tire 326 00:17:43,280 --> 00:17:46,680 Speaker 1: and then distributing torque where it's needed to take advantage 327 00:17:46,680 --> 00:17:50,800 Speaker 1: of that UM, which means that this actually can expand 328 00:17:50,800 --> 00:17:53,520 Speaker 1: the performance envelope even on dry paving, not just in 329 00:17:53,760 --> 00:17:57,960 Speaker 1: you know, wet or slippery conditions. UM. And that lets 330 00:17:58,040 --> 00:18:03,520 Speaker 1: us use the OL wild drives to an advantage without 331 00:18:03,880 --> 00:18:06,119 Speaker 1: using it in places but we don't need it waste 332 00:18:06,160 --> 00:18:10,680 Speaker 1: fuel right UM. And then there's a couple of places 333 00:18:10,720 --> 00:18:12,840 Speaker 1: where those two ideas the g vactor control trying to 334 00:18:12,880 --> 00:18:15,120 Speaker 1: get the car turning in precisely, and what the oil 335 00:18:15,200 --> 00:18:17,880 Speaker 1: drive is doing where they don't get along where we're 336 00:18:18,000 --> 00:18:20,360 Speaker 1: If we're driving the rear wheels at a certain time, 337 00:18:20,680 --> 00:18:23,280 Speaker 1: it will make the car resists turning in because they're 338 00:18:23,280 --> 00:18:25,440 Speaker 1: trying to go the same speed. And so we have 339 00:18:25,560 --> 00:18:27,879 Speaker 1: to integrate those two systems so that the g vactor 340 00:18:27,920 --> 00:18:30,000 Speaker 1: control gets the authority right at the moment that it 341 00:18:30,080 --> 00:18:32,480 Speaker 1: needs the car to turn. And then when you're steady state, 342 00:18:32,520 --> 00:18:34,480 Speaker 1: it goes back and sends more to the rear, and 343 00:18:34,480 --> 00:18:36,440 Speaker 1: then it straights back out and can even drag a 344 00:18:36,480 --> 00:18:38,879 Speaker 1: little bit more to the rear to help. So it 345 00:18:38,920 --> 00:18:41,680 Speaker 1: is a really complicated interplayoffs software to get all these 346 00:18:41,680 --> 00:18:44,120 Speaker 1: systems and the cars to talk to each other. Uh. 347 00:18:44,119 --> 00:18:47,439 Speaker 1: And it's it has to to get it to work 348 00:18:47,840 --> 00:18:51,879 Speaker 1: at the speed that our mind is processing things so 349 00:18:51,920 --> 00:18:55,480 Speaker 1: that it feels so that we were really fast in 350 00:18:55,880 --> 00:18:59,400 Speaker 1: what we can recognize, UM. So to to make it 351 00:18:59,440 --> 00:19:01,680 Speaker 1: so we don't feel that it's doing something, but it 352 00:19:01,760 --> 00:19:03,920 Speaker 1: just feels seamless, and it feels like as one unit. 353 00:19:04,240 --> 00:19:07,160 Speaker 1: We had to redo a bunch of the computer hardware 354 00:19:07,160 --> 00:19:10,600 Speaker 1: in the car to communicate faster, to get the signals 355 00:19:10,600 --> 00:19:13,360 Speaker 1: from the steering into the into the thing that makes 356 00:19:13,359 --> 00:19:15,280 Speaker 1: the decisions, and then into the into the e c 357 00:19:15,440 --> 00:19:18,399 Speaker 1: U two from the to change the engine, now putta 358 00:19:18,480 --> 00:19:22,240 Speaker 1: to change the all world drive. Um, if I remember right, 359 00:19:22,240 --> 00:19:24,879 Speaker 1: I think we've got fifty milliseconds from steering input before 360 00:19:25,000 --> 00:19:26,720 Speaker 1: something has to happen at the other end or else 361 00:19:26,840 --> 00:19:29,640 Speaker 1: people will notice. All right, Jonathan from the booth again, 362 00:19:29,680 --> 00:19:32,960 Speaker 1: we're going to rejoin Dave a little further into that 363 00:19:33,000 --> 00:19:35,400 Speaker 1: conversation he had with us. You know, we talked about 364 00:19:35,400 --> 00:19:37,280 Speaker 1: a lot of stuff in that conversation, not all of 365 00:19:37,320 --> 00:19:40,720 Speaker 1: it pertains kind of to this human centric design concept, 366 00:19:41,160 --> 00:19:42,920 Speaker 1: but he gave us a little more insight into the 367 00:19:43,000 --> 00:19:47,040 Speaker 1: challenges behind making the interior of a vehicle quiet without 368 00:19:47,240 --> 00:19:51,320 Speaker 1: making it too quiet. Again, this gets to that concept 369 00:19:51,440 --> 00:19:54,879 Speaker 1: of you want to make an experience for the end user, 370 00:19:55,320 --> 00:19:57,960 Speaker 1: but you have to make sure you're giving the right experience. 371 00:19:57,960 --> 00:20:01,480 Speaker 1: It's not just an experience, but the correct one. So 372 00:20:01,520 --> 00:20:04,160 Speaker 1: we learned there's a very delicate balance to all of that. 373 00:20:04,440 --> 00:20:08,080 Speaker 1: Here's Dave to explain a little further. Hopefully the first 374 00:20:08,080 --> 00:20:10,760 Speaker 1: thing I'll notice is that it's quiet. You know, that 375 00:20:11,000 --> 00:20:13,159 Speaker 1: used to be a weak point of ours. Because well, again, 376 00:20:13,720 --> 00:20:16,560 Speaker 1: steering handling and n VH guys are fighting each farther, 377 00:20:16,680 --> 00:20:18,520 Speaker 1: and we always wanted our cars to handle really well 378 00:20:18,560 --> 00:20:21,520 Speaker 1: and sort of trying to elevate ourselves to the point 379 00:20:21,560 --> 00:20:23,200 Speaker 1: where we can have the steering handling and have the 380 00:20:23,240 --> 00:20:26,080 Speaker 1: car drive right and still be quite uncomfortable. I'm recognizing 381 00:20:26,080 --> 00:20:29,399 Speaker 1: how important that is. UM. We've sort of expanded our 382 00:20:29,560 --> 00:20:34,800 Speaker 1: our performance envelope and a lot of looking at sort 383 00:20:34,800 --> 00:20:37,680 Speaker 1: of how people hear things, what frequency ranges matter to them, 384 00:20:37,680 --> 00:20:40,720 Speaker 1: and what how it actually affects people. Um. And one 385 00:20:40,720 --> 00:20:43,040 Speaker 1: of the things we've started figure out is that we're 386 00:20:43,119 --> 00:20:47,840 Speaker 1: super sensitive to direction of sound, which means that if 387 00:20:47,880 --> 00:20:50,040 Speaker 1: you hear, if the sound does get into the car 388 00:20:50,680 --> 00:20:53,240 Speaker 1: and then uh, you hear reflect off the other window, 389 00:20:53,240 --> 00:20:57,000 Speaker 1: you'll pick up that reflection, maybe not consciously, but it 390 00:20:57,080 --> 00:20:59,639 Speaker 1: bothers you more than that same amount of noise just 391 00:20:59,680 --> 00:21:03,359 Speaker 1: coming one high. So we put more damping into the 392 00:21:03,359 --> 00:21:05,639 Speaker 1: car so that found from do get in damp out quickly. 393 00:21:05,840 --> 00:21:11,480 Speaker 1: It should be good for recording, right right. UM. And 394 00:21:11,560 --> 00:21:14,760 Speaker 1: we've also worked really a lot on isolation from outside noises, 395 00:21:14,800 --> 00:21:16,480 Speaker 1: so you don't hear the car next to you so much, 396 00:21:16,800 --> 00:21:19,440 Speaker 1: and that We're trying to strack a balance because if 397 00:21:19,480 --> 00:21:24,560 Speaker 1: you isolate too much, it's you don't practical reason became 398 00:21:24,640 --> 00:21:27,280 Speaker 1: the Siren's But also at a more subtle level, you 399 00:21:27,480 --> 00:21:31,320 Speaker 1: don't feel connected to what you're doing well, and you 400 00:21:31,480 --> 00:21:33,480 Speaker 1: you feel like you're not really controlling the car. You're 401 00:21:33,520 --> 00:21:36,320 Speaker 1: driving a video game, like you don't feel We want 402 00:21:36,359 --> 00:21:39,200 Speaker 1: to hear the road and feel the road just enough 403 00:21:39,440 --> 00:21:42,560 Speaker 1: to feel connected and not enough to be annoyed. And 404 00:21:42,680 --> 00:21:45,119 Speaker 1: that's the same with outside noises, like you want to 405 00:21:45,119 --> 00:21:47,520 Speaker 1: know that car is there, but you don't want to 406 00:21:47,840 --> 00:21:50,440 Speaker 1: know exactly what's wrong with his brakes. Jonathan, run the 407 00:21:50,440 --> 00:21:53,080 Speaker 1: boot one more time. Another thing that Dave said that 408 00:21:53,119 --> 00:21:55,919 Speaker 1: I wanted to share was about how the team worked 409 00:21:56,320 --> 00:21:58,600 Speaker 1: on the sound system for the Maths to See X 410 00:21:58,640 --> 00:22:03,080 Speaker 1: thirty and they did to put the sub whiffers in 411 00:22:03,119 --> 00:22:06,680 Speaker 1: a very special section of the vehicle and move it 412 00:22:06,720 --> 00:22:09,479 Speaker 1: away from the traditional place, which is within the doors. 413 00:22:09,960 --> 00:22:12,280 Speaker 1: And in order to do that, they had to communicate 414 00:22:12,320 --> 00:22:16,040 Speaker 1: and collaborate with the safety team to make sure that 415 00:22:16,080 --> 00:22:18,880 Speaker 1: this design element they wanted to include would be factored 416 00:22:18,880 --> 00:22:21,720 Speaker 1: into the structure of the vehicle from the very beginning. 417 00:22:21,960 --> 00:22:25,080 Speaker 1: Here's what Dave had to say. One of the kind 418 00:22:25,080 --> 00:22:28,919 Speaker 1: of trick ways that we improve the noise, the outside 419 00:22:28,960 --> 00:22:32,000 Speaker 1: noise isolation in this car and improved the audio quality 420 00:22:32,080 --> 00:22:34,639 Speaker 1: in the car was taking the big speakers out of 421 00:22:34,640 --> 00:22:38,600 Speaker 1: the doors. Everyone has their their subs in the door, right, 422 00:22:38,640 --> 00:22:42,320 Speaker 1: because that's whether you have enough room for Um, that's 423 00:22:42,320 --> 00:22:47,200 Speaker 1: a really inefficient place for a driver. Uh, in terms 424 00:22:47,200 --> 00:22:49,480 Speaker 1: of the space of the car. It's it's driving the 425 00:22:49,760 --> 00:22:52,840 Speaker 1: sounding that volume in the long spot. Um. And it 426 00:22:52,880 --> 00:22:56,560 Speaker 1: also is a noise path from the outside, right. So um, 427 00:22:56,720 --> 00:23:00,320 Speaker 1: we moved them up into the under the dash in 428 00:23:00,480 --> 00:23:03,760 Speaker 1: sort of in the corner of the room. Because anytime 429 00:23:03,800 --> 00:23:05,359 Speaker 1: you corner a load of speaker, the sound quality is 430 00:23:05,359 --> 00:23:07,520 Speaker 1: a lot better, right. Um. So it's a much more 431 00:23:07,560 --> 00:23:09,159 Speaker 1: efficient way to get sound in the car. So if 432 00:23:09,160 --> 00:23:11,080 Speaker 1: we don't have to put as much power in to 433 00:23:11,240 --> 00:23:15,200 Speaker 1: get a better sound quality at the people's ears. Um. 434 00:23:15,240 --> 00:23:19,479 Speaker 1: But also let's to steal off those doors. Um. This 435 00:23:19,560 --> 00:23:22,120 Speaker 1: is something I think everybody understood should be done. It's 436 00:23:22,119 --> 00:23:24,720 Speaker 1: incredibly hard to do because the corners of the of 437 00:23:24,840 --> 00:23:29,080 Speaker 1: the interior are actually a really critical crash structure and 438 00:23:29,119 --> 00:23:32,000 Speaker 1: there's a lot of there's a lot of other departments 439 00:23:33,080 --> 00:23:36,000 Speaker 1: buying for for real estate there right, Because the if 440 00:23:36,040 --> 00:23:38,760 Speaker 1: you crash into something, the load from the bumper goes 441 00:23:38,800 --> 00:23:40,720 Speaker 1: into the frame rails, which go right back into that 442 00:23:40,760 --> 00:23:42,600 Speaker 1: corner of the car, and that's where the load has 443 00:23:42,640 --> 00:23:45,159 Speaker 1: to stop crumpling things. We want everything in front of 444 00:23:45,160 --> 00:23:47,960 Speaker 1: the windshield to crumple and everything inside not too. And 445 00:23:48,000 --> 00:23:52,679 Speaker 1: so that's a really strong structural corner. So normally you 446 00:23:52,720 --> 00:23:55,240 Speaker 1: develop a car, you develt a crash structure first and 447 00:23:55,240 --> 00:23:58,239 Speaker 1: then everybody gets to work on after those. And we 448 00:23:58,280 --> 00:24:00,879 Speaker 1: had to get this concept of trying to move the 449 00:24:00,880 --> 00:24:04,640 Speaker 1: speakers up into the corners before we started the platform development, 450 00:24:05,119 --> 00:24:07,679 Speaker 1: to say, hey, crash guys, you have a space for 451 00:24:07,680 --> 00:24:10,240 Speaker 1: the speaker while you're doing that, and build that concept 452 00:24:10,320 --> 00:24:13,160 Speaker 1: in all right, and and so it was a really 453 00:24:13,680 --> 00:24:16,680 Speaker 1: sort of big accomplishment for us to pull off logistically. 454 00:24:17,480 --> 00:24:19,400 Speaker 1: Dave was a lot of fun to talk to, and 455 00:24:19,480 --> 00:24:22,639 Speaker 1: he helped us understand how these decisions to craft a 456 00:24:22,680 --> 00:24:29,479 Speaker 1: specific experience manifest in actual real world decisions and engineering choices. Now, 457 00:24:29,560 --> 00:24:32,679 Speaker 1: these are things I typically take for granted. Whenever I 458 00:24:32,800 --> 00:24:36,639 Speaker 1: use a product, I generally only think, you know, something like, wow, 459 00:24:36,720 --> 00:24:39,360 Speaker 1: this thing is really easy to use or wow, this 460 00:24:39,440 --> 00:24:42,080 Speaker 1: is a lot of fun, or sometimes on the flip side, 461 00:24:42,119 --> 00:24:45,520 Speaker 1: because not everything is positive. Sometimes I think, who the 462 00:24:45,520 --> 00:24:47,920 Speaker 1: heck thought this was a good design choice? Is so 463 00:24:48,000 --> 00:24:51,600 Speaker 1: inconvenient it's hard to get to. If you ever had 464 00:24:51,600 --> 00:24:54,919 Speaker 1: a user interface where you've had to navigate, you know, 465 00:24:55,040 --> 00:24:58,080 Speaker 1: five steps beyond what you thought would be necessary, you 466 00:24:58,119 --> 00:25:00,280 Speaker 1: know what I'm talking about. It's it ends up being 467 00:25:00,680 --> 00:25:05,520 Speaker 1: so frustrating that it actually creates a disincentive for you 468 00:25:05,640 --> 00:25:09,640 Speaker 1: to use the technology. But I rarely give it much 469 00:25:09,680 --> 00:25:13,399 Speaker 1: more consideration than that sort of surface level. But talking 470 00:25:13,400 --> 00:25:16,200 Speaker 1: with engineers really reveals how much thought has to go 471 00:25:16,280 --> 00:25:19,480 Speaker 1: into this, and it also explains that sometimes it goes 472 00:25:19,520 --> 00:25:23,240 Speaker 1: wrong because you have multiple groups all trying to get 473 00:25:23,280 --> 00:25:27,240 Speaker 1: their various pieces of the puzzle into place, and sometimes 474 00:25:27,280 --> 00:25:31,280 Speaker 1: that means that their peace and someone else's piece, while 475 00:25:31,320 --> 00:25:34,679 Speaker 1: they were meant to fit together, don't. They might overlap, 476 00:25:34,920 --> 00:25:38,080 Speaker 1: they might conflict, they might be a gap between them. 477 00:25:38,080 --> 00:25:40,600 Speaker 1: Those sort of things can happen when things don't go well. 478 00:25:41,119 --> 00:25:43,399 Speaker 1: Now we're going to take another quick break, but when 479 00:25:43,480 --> 00:25:46,520 Speaker 1: we come back, will rejoin me in the Mazda c 480 00:25:46,880 --> 00:25:57,200 Speaker 1: X thirty. All right, So now we're gonna pick back 481 00:25:57,320 --> 00:26:00,000 Speaker 1: up with me at the auto show, So you're gonna 482 00:26:00,080 --> 00:26:02,840 Speaker 1: hear the audio audio quality change again, and I'll be 483 00:26:02,880 --> 00:26:06,440 Speaker 1: talking about the importance of collaboration and communication, and away 484 00:26:06,880 --> 00:26:09,040 Speaker 1: we go. That ends up saving a lot of time 485 00:26:09,359 --> 00:26:12,239 Speaker 1: in the design process there. I've seen a lot of 486 00:26:12,240 --> 00:26:14,800 Speaker 1: different products come out where it was only in the 487 00:26:14,800 --> 00:26:17,960 Speaker 1: testing phase that they realized that there were these sort 488 00:26:18,000 --> 00:26:20,479 Speaker 1: of issues, and then it just meant having to go 489 00:26:20,520 --> 00:26:23,359 Speaker 1: back through a redesign process, and typically it tends to 490 00:26:23,400 --> 00:26:25,800 Speaker 1: be very similar to the first design process, which means 491 00:26:26,080 --> 00:26:29,640 Speaker 1: you still have that problem of these isolated silos, these 492 00:26:29,680 --> 00:26:33,440 Speaker 1: isolated departments that are each working towards their own goal 493 00:26:34,040 --> 00:26:38,399 Speaker 1: and not collaborating closely enough to get the end result 494 00:26:38,440 --> 00:26:42,400 Speaker 1: they want. So that's a huge challenge in design in general. 495 00:26:43,200 --> 00:26:46,440 Speaker 1: So you get to the point where you've built your solution, 496 00:26:46,600 --> 00:26:51,119 Speaker 1: you've tested your solution, Uh, your systems are not in isolation, 497 00:26:51,160 --> 00:26:53,320 Speaker 1: You've figured that part out, You've got your systems all 498 00:26:53,320 --> 00:26:57,200 Speaker 1: working together, and then you see how well it works 499 00:26:57,200 --> 00:26:59,800 Speaker 1: on paper, and then you throw people into it and 500 00:27:00,040 --> 00:27:03,040 Speaker 1: eyes you know technology. I've I've often told this to 501 00:27:03,320 --> 00:27:09,000 Speaker 1: people when I talk about my role at the podcast Realm. 502 00:27:09,320 --> 00:27:11,159 Speaker 1: You know, I've got a lot of podcast friends, a 503 00:27:11,200 --> 00:27:14,639 Speaker 1: lot of coworkers who do great work in all sorts 504 00:27:14,640 --> 00:27:18,040 Speaker 1: of fields. But they're talking about stuff like, you know, 505 00:27:18,720 --> 00:27:22,960 Speaker 1: society and culture and and and money and stuff. What 506 00:27:23,119 --> 00:27:26,520 Speaker 1: don't make sense, y'all. Technology, it makes sense. It either 507 00:27:26,560 --> 00:27:28,960 Speaker 1: works or it doesn't. I have the easiest job, don't 508 00:27:29,040 --> 00:27:34,080 Speaker 1: tell anyone. But when you throw people into things, it 509 00:27:34,119 --> 00:27:39,440 Speaker 1: gets messy because people they have expectations, they have desires, 510 00:27:39,440 --> 00:27:42,960 Speaker 1: they have motivations, they have things that technology on its 511 00:27:42,960 --> 00:27:45,560 Speaker 1: own does not have. As long as sky net has 512 00:27:45,600 --> 00:27:51,000 Speaker 1: not yet gone you know completely, you know, self aware. 513 00:27:52,640 --> 00:27:55,960 Speaker 1: I'm assuming that we're okay at the moment, but yeah, 514 00:27:56,000 --> 00:28:00,600 Speaker 1: people make things complicated. When people are involved, you then 515 00:28:00,680 --> 00:28:05,159 Speaker 1: have to really evaluate what your work actually means in 516 00:28:05,240 --> 00:28:07,879 Speaker 1: the real world. I want to give you, guys an 517 00:28:07,920 --> 00:28:11,760 Speaker 1: example that's unrelated to vehicles for a moment to kind 518 00:28:11,760 --> 00:28:14,840 Speaker 1: of explain what I'm thinking about here. I once intended 519 00:28:14,880 --> 00:28:18,159 Speaker 1: to talk with some roboticists who were talking about the 520 00:28:18,240 --> 00:28:20,480 Speaker 1: challenges they faced when they were trying to design a 521 00:28:20,600 --> 00:28:24,359 Speaker 1: robot that would that would interact with humans within a 522 00:28:24,440 --> 00:28:31,080 Speaker 1: human space, and that is a difficult thing to really engineer. 523 00:28:31,440 --> 00:28:36,280 Speaker 1: To create a robot that can seamlessly interact with humans. 524 00:28:36,320 --> 00:28:40,040 Speaker 1: So they sat down and they identified their various goals 525 00:28:40,040 --> 00:28:42,320 Speaker 1: and objectives. They sat down and said, all right, these 526 00:28:42,320 --> 00:28:44,960 Speaker 1: are the things that are important to us. We need 527 00:28:45,000 --> 00:28:47,040 Speaker 1: to make sure that our robot does these things. And 528 00:28:47,080 --> 00:28:50,480 Speaker 1: they were parameters like this is how close a robot 529 00:28:50,520 --> 00:28:53,720 Speaker 1: can get to another human being before it has to 530 00:28:53,760 --> 00:28:56,160 Speaker 1: stop because otherwise it's going to be crowding someone. Or 531 00:28:56,520 --> 00:28:59,120 Speaker 1: this is how close a robot can get to a 532 00:28:59,320 --> 00:29:02,720 Speaker 1: stationary object. This is how fast the robots should move 533 00:29:02,720 --> 00:29:06,160 Speaker 1: through the environment. This is how the robot should respond 534 00:29:06,320 --> 00:29:10,360 Speaker 1: if someone were to address it. So a whole list 535 00:29:10,400 --> 00:29:14,400 Speaker 1: of rules that they had to figure out and then design, 536 00:29:14,920 --> 00:29:17,440 Speaker 1: and this took months and months and months of testing. 537 00:29:18,160 --> 00:29:20,120 Speaker 1: There was a point where a robot was staring at 538 00:29:20,120 --> 00:29:21,760 Speaker 1: a door for two hours trying to figure out how 539 00:29:21,800 --> 00:29:24,000 Speaker 1: to open it. That's the sort of stuff we're talking about. 540 00:29:25,160 --> 00:29:27,320 Speaker 1: They solve all these problems and then they put the 541 00:29:27,400 --> 00:29:31,080 Speaker 1: robot into an actual human environment, and that's when everything 542 00:29:31,120 --> 00:29:35,560 Speaker 1: went pear shaped, I guess we could say, because they 543 00:29:35,720 --> 00:29:40,040 Speaker 1: realized that the human beings in that particular environment had 544 00:29:40,080 --> 00:29:43,000 Speaker 1: an expectation of how the robot was supposed to behave. 545 00:29:43,080 --> 00:29:45,880 Speaker 1: It was a robot, but the robot wasn't behaving the 546 00:29:45,880 --> 00:29:49,880 Speaker 1: way they thought a robot should behave. The robot was 547 00:29:49,920 --> 00:29:52,160 Speaker 1: behaving the way the engineers had thought the robots should 548 00:29:52,160 --> 00:29:54,600 Speaker 1: behave based on the way humans behave within the same 549 00:29:54,680 --> 00:29:58,160 Speaker 1: sort of social space. Now that meant that the people 550 00:29:58,160 --> 00:30:02,400 Speaker 1: who were actually encountering the robot, we're uncomfortable around the robot. 551 00:30:02,600 --> 00:30:06,040 Speaker 1: It felt weird. It was the sort of Uncanny Valley, 552 00:30:06,080 --> 00:30:10,400 Speaker 1: except instead of appearance, it was in behavior. So uncanny valley, 553 00:30:10,400 --> 00:30:14,040 Speaker 1: for those who are not familiar, is this gap when 554 00:30:14,080 --> 00:30:19,080 Speaker 1: you start to approach something that appears to be alive 555 00:30:19,480 --> 00:30:22,920 Speaker 1: but still has certain elements that indicate it is not 556 00:30:23,000 --> 00:30:25,480 Speaker 1: truly alive. We usually use it to describe things like 557 00:30:25,560 --> 00:30:27,680 Speaker 1: c G I characters, where a c G I character 558 00:30:27,720 --> 00:30:32,480 Speaker 1: looks almost but not quite real. The same thing is 559 00:30:32,480 --> 00:30:37,320 Speaker 1: true with behaviors. So the roboticists discovered that these robots 560 00:30:37,800 --> 00:30:40,600 Speaker 1: were not performing the way they needed to, that people 561 00:30:40,600 --> 00:30:43,280 Speaker 1: were not responding to them the way that they had 562 00:30:43,320 --> 00:30:46,920 Speaker 1: anticipated because it wasn't robotic enough. They actually had to 563 00:30:46,920 --> 00:30:49,560 Speaker 1: go back to the drawing board and go through and 564 00:30:49,640 --> 00:30:54,480 Speaker 1: start rethinking their whole process of creating robots that could 565 00:30:54,520 --> 00:30:58,920 Speaker 1: interact in social spaces and make them more robotic. That 566 00:30:59,080 --> 00:31:01,480 Speaker 1: was a fail. You're of an approach of a human 567 00:31:01,480 --> 00:31:04,440 Speaker 1: centric design in the sense that the people creating the 568 00:31:04,520 --> 00:31:10,320 Speaker 1: robots had not anticipated that human reaction, and it shows 569 00:31:10,640 --> 00:31:13,600 Speaker 1: that when you throw humans into an equation, things get 570 00:31:13,640 --> 00:31:17,680 Speaker 1: a little more complicated. It's not as straightforward as saying 571 00:31:18,320 --> 00:31:24,120 Speaker 1: this particular piece of technology needs to do task in 572 00:31:24,320 --> 00:31:26,880 Speaker 1: why amount of time and it has to have a 573 00:31:26,880 --> 00:31:31,400 Speaker 1: certain level of reliability. It means more than that. It 574 00:31:31,440 --> 00:31:37,760 Speaker 1: means defining things like a feeling, intention, defining how a 575 00:31:37,840 --> 00:31:44,360 Speaker 1: person should experience the technology. And this goes well beyond technology. Obviously, 576 00:31:44,400 --> 00:31:47,040 Speaker 1: it goes to everything that we ever designed. But really 577 00:31:47,040 --> 00:31:49,640 Speaker 1: in tech, it's something that you either get or you don't, 578 00:31:49,840 --> 00:31:53,000 Speaker 1: and if you get it when you're designing, you can 579 00:31:53,040 --> 00:31:58,960 Speaker 1: create something that actually has a legit special feeling when 580 00:31:59,000 --> 00:32:03,760 Speaker 1: you experience it. It's a very tough challenge because obviously, 581 00:32:03,800 --> 00:32:06,240 Speaker 1: the other big issue you have is that people are different. 582 00:32:06,320 --> 00:32:09,080 Speaker 1: You know, we have general things that kind of unite us, 583 00:32:09,080 --> 00:32:14,600 Speaker 1: but we're all individuals. We all have our own preferences, 584 00:32:14,720 --> 00:32:17,640 Speaker 1: our own things that that maybe annoy us, uh and 585 00:32:17,680 --> 00:32:20,920 Speaker 1: our own expectations, so it also means having to identify 586 00:32:21,000 --> 00:32:26,440 Speaker 1: which ones are the most important to whatever end result 587 00:32:26,480 --> 00:32:30,720 Speaker 1: you're looking for. So one of the things that really 588 00:32:30,800 --> 00:32:34,040 Speaker 1: we heard a lot when we were here over in 589 00:32:34,080 --> 00:32:37,520 Speaker 1: the auto show over at Mazda's this this concept of 590 00:32:37,640 --> 00:32:41,480 Speaker 1: feel alive, that you want to feel alive when you're 591 00:32:41,520 --> 00:32:46,320 Speaker 1: actually using the vehicle, and vehicles are such an important 592 00:32:46,480 --> 00:32:49,960 Speaker 1: central piece of technology in our lives. That is not 593 00:32:50,040 --> 00:32:53,320 Speaker 1: a small task, and it's not lips service. It's not 594 00:32:53,480 --> 00:32:58,480 Speaker 1: something that is just a tagline. It's a guiding philosophy. 595 00:32:58,520 --> 00:33:02,360 Speaker 1: That's the philosophy that guides the decisions that the engineers 596 00:33:02,360 --> 00:33:04,320 Speaker 1: are making in order to make a vehicle that is 597 00:33:05,360 --> 00:33:08,480 Speaker 1: fun to drive, that it's safe, that's efficient, that it 598 00:33:08,520 --> 00:33:10,400 Speaker 1: has all the things you expect a vehicle to have, 599 00:33:10,800 --> 00:33:12,800 Speaker 1: but that when you are behind the wheel and you're 600 00:33:12,840 --> 00:33:18,160 Speaker 1: actually driving it, you have the sensation of feeling alive. 601 00:33:18,280 --> 00:33:22,480 Speaker 1: That's sort of exhilarating feeling, and that it's something that 602 00:33:22,520 --> 00:33:25,320 Speaker 1: goes beyond just your experience behind the wheel. It's something 603 00:33:25,360 --> 00:33:28,240 Speaker 1: that is actually integrated into your experience of moving through 604 00:33:28,320 --> 00:33:31,720 Speaker 1: an environment. So when you start thinking about that, you're 605 00:33:31,760 --> 00:33:36,400 Speaker 1: thinking not just trying to define everything that's on a 606 00:33:36,560 --> 00:33:40,640 Speaker 1: dashboard or just an easy reach of the driver. You're 607 00:33:40,680 --> 00:33:43,400 Speaker 1: thinking about an experience that goes well beyond that, as 608 00:33:43,440 --> 00:33:47,400 Speaker 1: the driver's maneuvering through different environments. That ends up being 609 00:33:47,400 --> 00:33:53,160 Speaker 1: a very important concept to guide all of your design philosophies. 610 00:33:53,840 --> 00:33:56,800 Speaker 1: And I was really impressed with the passion that I 611 00:33:56,960 --> 00:34:00,680 Speaker 1: encountered when I talked with people from Mazda. All shared 612 00:34:00,800 --> 00:34:06,040 Speaker 1: that same sort of uh, deep desire to create that 613 00:34:06,160 --> 00:34:10,000 Speaker 1: kind of experience. And this is not something that is 614 00:34:10,080 --> 00:34:15,080 Speaker 1: easy to engineer. It's not something you typically hear from engineers. Uh. 615 00:34:15,160 --> 00:34:18,759 Speaker 1: This also kind of brings us to a dichotomy I 616 00:34:18,880 --> 00:34:23,240 Speaker 1: tend to encounter in the field of technology. Broadly speaking, 617 00:34:23,600 --> 00:34:27,239 Speaker 1: there are two major camps I tend to encounter when 618 00:34:27,280 --> 00:34:31,680 Speaker 1: I'm looking at different types of gadgets and vehicles and 619 00:34:31,719 --> 00:34:34,760 Speaker 1: things like that. One is that I see a camp 620 00:34:34,880 --> 00:34:40,560 Speaker 1: that really emphasizes esthetic over everything else, so that the 621 00:34:40,640 --> 00:34:44,120 Speaker 1: look of it is supposed to be extremely evocative and 622 00:34:44,239 --> 00:34:48,360 Speaker 1: that it makes you want to use it in some way, 623 00:34:48,400 --> 00:34:52,080 Speaker 1: but that is the guiding principle behind the design. The 624 00:34:52,120 --> 00:34:55,360 Speaker 1: other I've seen is a more I think of it 625 00:34:55,400 --> 00:34:58,319 Speaker 1: as the engineering approach in the sense that it needs 626 00:34:58,400 --> 00:34:59,960 Speaker 1: to work, it needs to be able to do the 627 00:35:00,080 --> 00:35:02,560 Speaker 1: things that it was supposed to do. Uh, And that 628 00:35:02,680 --> 00:35:07,440 Speaker 1: becomes primary and aesthetic is is secondary, or maybe tertiary, 629 00:35:07,520 --> 00:35:11,160 Speaker 1: or maybe for some companies, not really a thing that 630 00:35:11,200 --> 00:35:14,520 Speaker 1: anyone thinks about. Uh. I'm sure many of you have 631 00:35:14,680 --> 00:35:17,399 Speaker 1: owned gadgets out there that fall into that category where 632 00:35:17,440 --> 00:35:19,480 Speaker 1: you think this thing is ugly as sin. It does 633 00:35:19,520 --> 00:35:21,160 Speaker 1: what it's supposed to do, but I don't like to 634 00:35:21,160 --> 00:35:25,000 Speaker 1: look at it. The real goal, I think, is trying 635 00:35:25,040 --> 00:35:30,760 Speaker 1: to bridge the gap between those two different philosophies, bringing 636 00:35:30,760 --> 00:35:34,640 Speaker 1: together the aesthetic and the desire to get the engineering 637 00:35:34,719 --> 00:35:38,879 Speaker 1: just right. Uh. I think a lot about my experience 638 00:35:38,920 --> 00:35:41,880 Speaker 1: with different things like mobile devices. That's the one that 639 00:35:41,920 --> 00:35:45,160 Speaker 1: I always think about about how I've had experiences with 640 00:35:45,239 --> 00:35:48,720 Speaker 1: ones where it looks really nice, it looks really sexy, 641 00:35:49,239 --> 00:35:52,920 Speaker 1: looks like it would go fast just standing still, and 642 00:35:53,000 --> 00:35:55,160 Speaker 1: others that it doesn't look so good, but you can 643 00:35:55,320 --> 00:35:58,560 Speaker 1: definitely see how everything works. Uh. And maybe you have 644 00:35:58,640 --> 00:36:02,919 Speaker 1: to learn the peculiarities of that particular system in order 645 00:36:02,920 --> 00:36:05,040 Speaker 1: for you to have a deeper appreciation, but you once 646 00:36:05,080 --> 00:36:09,040 Speaker 1: you do, it works just fine. Marrying those two is 647 00:36:09,120 --> 00:36:13,040 Speaker 1: really challenging, but it's also a very important part of 648 00:36:13,040 --> 00:36:18,600 Speaker 1: this human centric focus. Knowing that people do value both 649 00:36:18,680 --> 00:36:23,000 Speaker 1: the aesthetic and the function of a device, and again 650 00:36:23,040 --> 00:36:26,160 Speaker 1: for something as important as a vehicle, it becomes even 651 00:36:26,440 --> 00:36:31,040 Speaker 1: more imperative that you get that just right. So to 652 00:36:31,160 --> 00:36:34,880 Speaker 1: achieve this, it's all the all these different processes, all 653 00:36:34,880 --> 00:36:37,440 Speaker 1: these different philosophies I've talked about, have to come together. 654 00:36:38,320 --> 00:36:43,080 Speaker 1: We heard about how at Mazda they are still very 655 00:36:43,640 --> 00:36:47,960 Speaker 1: focused on very traditional ways of modeling, say the exterior 656 00:36:47,960 --> 00:36:50,960 Speaker 1: of a car, doing it through clay first and sculpting 657 00:36:51,040 --> 00:36:54,760 Speaker 1: it so that you can get exactly the right feel. 658 00:36:55,239 --> 00:36:59,440 Speaker 1: You know, you can very carefully shave away a tiny 659 00:36:59,640 --> 00:37:02,080 Speaker 1: slow ver of clay in order to get just the 660 00:37:02,160 --> 00:37:05,439 Speaker 1: right shape or just the right curve, and doing all 661 00:37:05,480 --> 00:37:09,320 Speaker 1: of that to meticulous detail until you do a full 662 00:37:09,440 --> 00:37:11,560 Speaker 1: scan of it and three D and then maybe then 663 00:37:11,640 --> 00:37:14,080 Speaker 1: at that point you can go to additive manufacturing, like 664 00:37:14,080 --> 00:37:18,279 Speaker 1: a three D printing sort of approach and create your 665 00:37:18,320 --> 00:37:22,080 Speaker 1: first three D printed version of the thing that you 666 00:37:22,120 --> 00:37:25,800 Speaker 1: have sculpted out of clay. They talked about how even 667 00:37:25,840 --> 00:37:29,560 Speaker 1: getting to a point where you could build the full 668 00:37:29,640 --> 00:37:35,040 Speaker 1: sized version of uh like a door, for example, that 669 00:37:35,120 --> 00:37:40,520 Speaker 1: if it wasn't just right, their engineers would take hand 670 00:37:41,160 --> 00:37:47,120 Speaker 1: uh handcrafted approaches to making sure they got exactly the 671 00:37:47,160 --> 00:37:50,320 Speaker 1: curve that they wanted in order to achieve the result 672 00:37:50,360 --> 00:37:52,480 Speaker 1: that they were going for. And that kind of level 673 00:37:53,080 --> 00:37:57,520 Speaker 1: of attention to detail is something that I find really inspiring. 674 00:37:57,600 --> 00:38:01,000 Speaker 1: It's also kind of intimidating you think about the scale 675 00:38:01,239 --> 00:38:05,720 Speaker 1: that that requires, and uh, that's not something that's easily 676 00:38:05,800 --> 00:38:10,200 Speaker 1: tackled either. So it's I feel like this is one 677 00:38:10,200 --> 00:38:13,279 Speaker 1: of those cases where you hear about the philosophy and 678 00:38:13,280 --> 00:38:15,320 Speaker 1: then you hear the stories behind it, and you really 679 00:38:15,360 --> 00:38:19,560 Speaker 1: feel that that you're talking to a company that's that's 680 00:38:19,600 --> 00:38:22,080 Speaker 1: walking the walk. They're not just talking the talk, they 681 00:38:22,120 --> 00:38:25,560 Speaker 1: really follow through with that, uh, and that to me 682 00:38:25,640 --> 00:38:30,600 Speaker 1: is really exciting. So I hope that I'm able to 683 00:38:30,920 --> 00:38:36,480 Speaker 1: kind of illustrate to you this incredible journey the the 684 00:38:36,560 --> 00:38:38,719 Speaker 1: from the point where you actually identify what it is 685 00:38:38,840 --> 00:38:41,399 Speaker 1: you want to do to the point of seeing it 686 00:38:41,520 --> 00:38:44,640 Speaker 1: come together and all the different challenges that face you 687 00:38:44,800 --> 00:38:49,040 Speaker 1: along the way. Uh. There are so many different examples 688 00:38:49,040 --> 00:38:53,319 Speaker 1: of that with any kind of technology, including vehicles, where 689 00:38:53,440 --> 00:38:55,839 Speaker 1: you can look at this and say, like if if 690 00:38:55,960 --> 00:38:59,400 Speaker 1: one of these systems didn't work just right, then it 691 00:38:59,400 --> 00:39:02,640 Speaker 1: would affect everything else. It becomes a cascading effect, and 692 00:39:02,719 --> 00:39:05,840 Speaker 1: no matter how good the design is on other elements 693 00:39:05,960 --> 00:39:09,479 Speaker 1: of the vehicle, you would still fall short of your goal. 694 00:39:09,880 --> 00:39:13,320 Speaker 1: And it really does drive home how enormous a challenge 695 00:39:13,440 --> 00:39:17,480 Speaker 1: this is. So I think they're playing me off. No, 696 00:39:17,840 --> 00:39:21,719 Speaker 1: I think that this has been an incredible experience for me. 697 00:39:22,400 --> 00:39:26,000 Speaker 1: This is an awesome studio. I can't wait to have 698 00:39:26,120 --> 00:39:32,759 Speaker 1: it installed in Atlanta. Uh everyone's laughing. Okay, well it 699 00:39:32,800 --> 00:39:35,400 Speaker 1: would still be great. I think uh Tari would have 700 00:39:35,600 --> 00:39:39,000 Speaker 1: fewer instances of me having you know, Diva fits in 701 00:39:39,040 --> 00:39:41,480 Speaker 1: the studio if I were recording in something like this 702 00:39:41,560 --> 00:39:45,800 Speaker 1: every single episode. Uh. Plus, I mean, there's it's spacious. 703 00:39:45,840 --> 00:39:49,280 Speaker 1: I could have so many guests in a single episode 704 00:39:49,320 --> 00:39:51,319 Speaker 1: and we could all have our own, our own nice 705 00:39:51,360 --> 00:39:55,680 Speaker 1: comfortable seats. I'm just really, it's a practical thing. I'm saying, 706 00:39:55,719 --> 00:39:58,839 Speaker 1: Like my studio back in Atlanta, we can fit maybe 707 00:39:58,840 --> 00:40:00,879 Speaker 1: three people in there before we get it's crowded. This time, 708 00:40:01,040 --> 00:40:04,400 Speaker 1: I can cram a lot of folks in here, including 709 00:40:04,719 --> 00:40:07,719 Speaker 1: sound engineers. So Tary it benefits you too, is what 710 00:40:07,760 --> 00:40:11,160 Speaker 1: I'm saying, but I want to think masdo for having 711 00:40:11,160 --> 00:40:14,200 Speaker 1: me come out here and to experience this and to 712 00:40:14,840 --> 00:40:19,760 Speaker 1: get a firsthand look at the culmination of this idea. 713 00:40:19,880 --> 00:40:22,520 Speaker 1: I've heard a lot about this philosophy. I've talked to 714 00:40:22,560 --> 00:40:28,440 Speaker 1: people who have been sort of really passionate about the 715 00:40:28,480 --> 00:40:32,040 Speaker 1: concept behind human centric design, but it's rare that I 716 00:40:32,040 --> 00:40:35,400 Speaker 1: actually get an experience, a truly immersive experience, because I 717 00:40:35,440 --> 00:40:39,560 Speaker 1: am actually in it where I see the fruition of that. 718 00:40:39,920 --> 00:40:41,600 Speaker 1: And when you get a chance to see that and 719 00:40:41,640 --> 00:40:45,879 Speaker 1: you you understand the decisions that went behind all those 720 00:40:45,920 --> 00:40:52,280 Speaker 1: design choices, you get a deeper appreciation for that process 721 00:40:52,360 --> 00:40:55,000 Speaker 1: and all the work that goes into just making something 722 00:40:55,080 --> 00:40:59,200 Speaker 1: actually happen. I think we all take for granted what 723 00:40:59,600 --> 00:41:03,040 Speaker 1: it makes to create a piece of technology like this. 724 00:41:03,400 --> 00:41:05,960 Speaker 1: You know, we might think of the manufacturing process, because 725 00:41:06,000 --> 00:41:08,839 Speaker 1: that's one that is easy to illustrate. It's you see 726 00:41:08,880 --> 00:41:13,239 Speaker 1: the factory line, But it's so much more than that. 727 00:41:13,280 --> 00:41:18,000 Speaker 1: The process takes years of work, years of engineering, years 728 00:41:18,000 --> 00:41:23,200 Speaker 1: of iterating and building upon past uh learnings, and two 729 00:41:23,880 --> 00:41:26,480 Speaker 1: continue to innovate on top of that. It is a 730 00:41:26,560 --> 00:41:32,840 Speaker 1: really interesting and inspiring experience to actually see this in person. 731 00:41:33,760 --> 00:41:38,160 Speaker 1: With that, I think I'm gonna wrap up because, um, 732 00:41:38,200 --> 00:41:41,560 Speaker 1: you know, I think I think i've I've covered it 733 00:41:41,600 --> 00:41:43,680 Speaker 1: pretty well. And plus I really want to have a 734 00:41:43,680 --> 00:41:46,120 Speaker 1: little more experience jumping around in the back seat of 735 00:41:46,160 --> 00:41:47,920 Speaker 1: this thing, because I've been saying in the front the 736 00:41:47,920 --> 00:41:49,759 Speaker 1: whole time and I haven't even experienced what the back 737 00:41:49,760 --> 00:41:52,560 Speaker 1: seats like. And I don't think anyone's gonna stop me 738 00:41:52,600 --> 00:41:54,399 Speaker 1: as long as I hold a microphone in my hand. 739 00:41:54,960 --> 00:41:57,440 Speaker 1: So I'm going to sign off, but don't tell anyone 740 00:41:57,440 --> 00:42:00,839 Speaker 1: who's actually here that I've done that. I'll just I'll 741 00:42:00,880 --> 00:42:03,960 Speaker 1: pretend like I'm still point. Oh they're broadcasting the whole 742 00:42:04,000 --> 00:42:06,480 Speaker 1: thing right now. Okay, well, alright, so on that. No, guys, 743 00:42:07,120 --> 00:42:10,160 Speaker 1: we're gonna wrap up this episode. Remember if you want 744 00:42:10,200 --> 00:42:12,880 Speaker 1: to reach out to me, text stuff at how stuff 745 00:42:12,920 --> 00:42:15,960 Speaker 1: works dot com, or you can pop onto Facebook or Twitter. 746 00:42:16,040 --> 00:42:19,840 Speaker 1: That's tech stuff hs W and uh, I look forward 747 00:42:20,040 --> 00:42:24,560 Speaker 1: to talking to you again really soon. And it's Jonathan 748 00:42:24,600 --> 00:42:27,440 Speaker 1: back in the studio. So I want to thank Mazda 749 00:42:27,480 --> 00:42:30,280 Speaker 1: for having me out at the auto show and getting 750 00:42:30,280 --> 00:42:33,040 Speaker 1: a chance to experience just a tiny sliver of the 751 00:42:33,080 --> 00:42:36,040 Speaker 1: work that they put into the c x thirty. You know, 752 00:42:36,080 --> 00:42:38,839 Speaker 1: I didn't get a chance to ride in it, but 753 00:42:39,280 --> 00:42:42,200 Speaker 1: it was really cool getting to see it up close 754 00:42:42,239 --> 00:42:44,440 Speaker 1: and actually sit in it and record an episode. It 755 00:42:44,480 --> 00:42:49,040 Speaker 1: was a fun experience. And uh and everyone there, by 756 00:42:49,040 --> 00:42:52,640 Speaker 1: the way, was incredibly kind and very helpful. So I 757 00:42:52,680 --> 00:42:55,120 Speaker 1: had a really good experience with everybody over there. So 758 00:42:55,160 --> 00:42:57,360 Speaker 1: thank you guys a lot. You guys are awesome. It 759 00:42:57,440 --> 00:43:01,160 Speaker 1: also reminded me that with every piece of technology I encounter, 760 00:43:01,239 --> 00:43:04,160 Speaker 1: no matter what it might be, there typically dozens or 761 00:43:04,280 --> 00:43:07,720 Speaker 1: hundreds or maybe even thousands of people who helped shape 762 00:43:07,760 --> 00:43:11,239 Speaker 1: that technology, maybe a little bit, maybe they helped define it, 763 00:43:11,480 --> 00:43:15,040 Speaker 1: but they all had their impact on that technology before 764 00:43:15,080 --> 00:43:18,239 Speaker 1: I ever got a chance to touch it. And that 765 00:43:18,360 --> 00:43:21,439 Speaker 1: when it all goes right, when everything is falling into 766 00:43:21,440 --> 00:43:24,160 Speaker 1: place properly, when people are able to collaborate, when they're 767 00:43:24,200 --> 00:43:28,040 Speaker 1: able to communicate, then they can produce technology in turn 768 00:43:28,239 --> 00:43:32,560 Speaker 1: creates a specific experience that reflects whatever the original intent 769 00:43:32,920 --> 00:43:36,200 Speaker 1: was of the design team. That comes to the very 770 00:43:36,880 --> 00:43:40,680 Speaker 1: goal of human centric design. And again, this is not 771 00:43:40,920 --> 00:43:44,960 Speaker 1: an easy thing to achieve. It is incredibly challenging. You 772 00:43:45,040 --> 00:43:48,799 Speaker 1: might define what you want people to feel like, but 773 00:43:49,400 --> 00:43:52,920 Speaker 1: then it may turn out that when people actually experience 774 00:43:53,000 --> 00:43:56,360 Speaker 1: the product, they feel something entirely different, and that you 775 00:43:56,400 --> 00:43:59,279 Speaker 1: could argue that that represents a failure on your part 776 00:43:59,560 --> 00:44:02,000 Speaker 1: as far as the design goes, and you have to 777 00:44:02,080 --> 00:44:07,480 Speaker 1: factor in human psychology and human behaviors that aren't something 778 00:44:07,480 --> 00:44:10,960 Speaker 1: that are so easy to quantify. As you know, how 779 00:44:11,000 --> 00:44:14,640 Speaker 1: efficient an engine is running, or how long a tire 780 00:44:15,080 --> 00:44:18,360 Speaker 1: can can be in service before you need to replace it. 781 00:44:18,640 --> 00:44:21,080 Speaker 1: Those are things that you can quantify much more easily. 782 00:44:21,440 --> 00:44:24,160 Speaker 1: So this human centric design philosophy is something that I 783 00:44:24,160 --> 00:44:27,839 Speaker 1: think is really fascinating, incredibly challenging, and when you get 784 00:44:27,880 --> 00:44:32,279 Speaker 1: it right, amazingly satisfying. All right, Well, that wraps up 785 00:44:32,560 --> 00:44:34,720 Speaker 1: this episode. And I know I gave a sign off 786 00:44:35,120 --> 00:44:37,680 Speaker 1: in the live section, but you know, I I feel 787 00:44:37,680 --> 00:44:40,240 Speaker 1: like if I don't do it again, I'm not really 788 00:44:40,239 --> 00:44:43,480 Speaker 1: doing my job. If you guys have suggestions for topics 789 00:44:43,560 --> 00:44:45,719 Speaker 1: you would like me to cover in future episodes of 790 00:44:45,719 --> 00:44:48,240 Speaker 1: tech Stuff, you can reach out via email the addresses 791 00:44:48,320 --> 00:44:51,560 Speaker 1: tech stuff at how stuffworks dot com, or you can 792 00:44:51,680 --> 00:44:54,360 Speaker 1: pop onto Facebook or Twitter the handle for both of 793 00:44:54,360 --> 00:44:58,799 Speaker 1: those Text Stuff hs W.
