I'm Manny, I'm Noah, this is Devin, 14 00:00:42,960 --> 00:00:44,879 Speaker 1: and this is no such thing the show where we 15 00:00:44,920 --> 00:00:48,559 Speaker 1: settle our dumb arguments and yours by actually doing the research. 16 00:00:49,000 --> 00:00:53,680 Speaker 1: On today's episode, why are headlights so motherfucking bright? And 17 00:00:53,720 --> 00:00:57,480 Speaker 1: can Biden's infrastructure bill actually be the thing that saves us? 18 00:01:00,200 --> 00:01:18,880 Speaker 2: There's no such thing, no such thing, such thing. 19 00:01:08,200 --> 00:01:18,480 Speaker 1: Touch So the other day, it's about seven o'clock at night, 20 00:01:18,680 --> 00:01:21,319 Speaker 1: I was I was out on long Island visiting the family, 21 00:01:21,959 --> 00:01:25,119 Speaker 1: and I was driving back to Brooklyn, and this time 22 00:01:25,160 --> 00:01:30,240 Speaker 1: of year gets start pretty early, which is fine for 23 00:01:30,840 --> 00:01:34,360 Speaker 1: most of the driving until I live by this expressway 24 00:01:34,400 --> 00:01:38,400 Speaker 1: we called the Jackie Robinson. It is notoriously a difficult 25 00:01:38,600 --> 00:01:43,640 Speaker 1: road to drive on. The lanes are more narrow, and 26 00:01:43,640 --> 00:01:48,680 Speaker 1: it's really windy, so and there's a lot of okay, 27 00:01:48,840 --> 00:01:50,840 Speaker 1: you got to go from your far right to your 28 00:01:50,880 --> 00:01:53,480 Speaker 1: far left to your far right because the exit's over here, 29 00:01:53,560 --> 00:01:56,120 Speaker 1: and then you need to exit on the right. So, 30 00:01:56,320 --> 00:02:00,000 Speaker 1: especially for someone who's inexperience, it is a difficult express 31 00:02:00,280 --> 00:02:04,560 Speaker 1: to be driving through. But what makes it even harder nowadays, 32 00:02:05,960 --> 00:02:10,960 Speaker 1: especially at night, is that everybody has the fucking brightest 33 00:02:11,000 --> 00:02:14,800 Speaker 1: lights you have ever seen in your entire life. So 34 00:02:15,880 --> 00:02:17,960 Speaker 1: you got people behind you whose lights are so bright 35 00:02:18,000 --> 00:02:21,280 Speaker 1: they're reflecting off your rear view mirror, and going in 36 00:02:21,320 --> 00:02:24,280 Speaker 1: your eyes, got people to the rid of you their 37 00:02:24,360 --> 00:02:26,680 Speaker 1: lights are so bright it's shine in the mirror in 38 00:02:26,720 --> 00:02:28,960 Speaker 1: your eyes. And then you got people on the opposite 39 00:02:29,639 --> 00:02:33,200 Speaker 1: Saturday Expressway coming towards you, and it looks like everyone 40 00:02:33,280 --> 00:02:35,639 Speaker 1: just has their high beams on. It's also a road 41 00:02:35,639 --> 00:02:38,280 Speaker 1: where you just gotta go or you'll get in an 42 00:02:38,280 --> 00:02:40,000 Speaker 1: accident if you go too slow. Based but you just 43 00:02:40,000 --> 00:02:43,320 Speaker 1: gotta drive fast, even if you don't feel comfortable driving fast. 44 00:02:44,880 --> 00:02:47,400 Speaker 1: There's so many times where, especially this time I'm driving 45 00:02:47,400 --> 00:02:49,040 Speaker 1: on it, I'm like, I can only see the car 46 00:02:49,080 --> 00:02:52,800 Speaker 1: in front of me. My visibility is about ten feet. 47 00:02:53,480 --> 00:02:55,480 Speaker 1: I don't know where the road is going outside of that. 48 00:02:55,800 --> 00:02:58,200 Speaker 1: Luckily enough, I've done this drive enough times that I 49 00:02:58,240 --> 00:02:58,920 Speaker 1: sort of know. 50 00:02:59,240 --> 00:03:00,240 Speaker 3: The direction that's gonna go. 51 00:03:00,800 --> 00:03:04,440 Speaker 1: But in my mind, I'm like, this feels so unsafe, 52 00:03:04,560 --> 00:03:06,320 Speaker 1: and I'm like, is this something I know? 53 00:03:06,360 --> 00:03:07,480 Speaker 3: I'm getting a little bit older. 54 00:03:08,200 --> 00:03:11,280 Speaker 1: I turned thirty two and last year I'm like, is 55 00:03:11,639 --> 00:03:12,919 Speaker 1: my eyesight. 56 00:03:12,639 --> 00:03:13,639 Speaker 3: Just so bad? 57 00:03:14,040 --> 00:03:17,200 Speaker 1: Or is is this just like a thing that everybody's 58 00:03:17,240 --> 00:03:19,760 Speaker 1: lights are just way too bright nowadays? It's making it 59 00:03:19,800 --> 00:03:20,680 Speaker 1: really hard to see. 60 00:03:21,280 --> 00:03:25,240 Speaker 4: No I have that. I've had so many similar experiences. 61 00:03:25,320 --> 00:03:28,560 Speaker 4: There are a lot of roads in Ohio that don't 62 00:03:28,600 --> 00:03:31,800 Speaker 4: have street lights. You're only relying on your headlights. 63 00:03:31,919 --> 00:03:33,200 Speaker 3: It's like when you're driving upstate. 64 00:03:33,600 --> 00:03:37,400 Speaker 4: Yeah, yeah, it's not just unique to Ohio, I suppose. 65 00:03:39,240 --> 00:03:43,920 Speaker 4: But I also have a stigmatism is very common. You 66 00:03:44,000 --> 00:03:47,880 Speaker 4: have it as well. Noah's been blessed with great genetics. 67 00:03:47,920 --> 00:03:50,000 Speaker 5: I think I bad eyesip, but not that way. 68 00:03:51,040 --> 00:03:54,640 Speaker 4: And uh, you know, at night time when I'm driving, 69 00:03:55,480 --> 00:03:58,800 Speaker 4: I so often I can't fucking see and I feel 70 00:03:58,920 --> 00:04:02,800 Speaker 4: a little crazy. I don't know if this is true, 71 00:04:02,840 --> 00:04:08,520 Speaker 4: but it feels like it's gotten worse over the past 72 00:04:08,600 --> 00:04:12,720 Speaker 4: like ten fifteen years. I've been driving since age seventeen, 73 00:04:13,280 --> 00:04:14,880 Speaker 4: and I don't remember it being this bad. 74 00:04:15,040 --> 00:04:17,520 Speaker 1: I don't either, and that's why I'm like, is my 75 00:04:17,600 --> 00:04:20,200 Speaker 1: eyesight getting worse or the light's getting brighter? 76 00:04:20,320 --> 00:04:20,520 Speaker 6: Yeah? 77 00:04:20,640 --> 00:04:21,640 Speaker 3: Right, because I. 78 00:04:21,600 --> 00:04:26,360 Speaker 1: Used to remember my parents complaining about driving at night, right, like, yeah, you. 79 00:04:26,279 --> 00:04:27,280 Speaker 3: Know, driving and that's hard. 80 00:04:27,440 --> 00:04:28,680 Speaker 1: And I used to be like, what are you talking about, 81 00:04:28,720 --> 00:04:29,760 Speaker 1: Like it it's a little bit darker. 82 00:04:29,839 --> 00:04:32,040 Speaker 5: Yeah, it's darker.

Yeah 169 00:08:15,040 --> 00:08:16,120 Speaker 7: exactly brightness? 170 00:08:16,200 --> 00:08:18,720 Speaker 1: Yeah, Like I'm I'm gonna go buy some lights off 171 00:08:18,720 --> 00:08:20,760 Speaker 1: Amazon and you know, take it to the shop, Like 172 00:08:20,760 --> 00:08:22,920 Speaker 1: are people doing that or is this just like out 173 00:08:22,960 --> 00:08:23,440 Speaker 1: the box? 174 00:08:24,000 --> 00:08:26,240 Speaker 3: This is what the cars are coming with now. 175 00:08:27,120 --> 00:08:32,160 Speaker 1: Such after the break, we talked to someone who's been 176 00:08:32,200 --> 00:08:35,240 Speaker 1: obsessed with car lighting ever since he was seven years old. 177 00:08:40,520 --> 00:08:41,400 Speaker 3: Okay, we're back. 178 00:08:41,760 --> 00:08:43,959 Speaker 5: I'm Noah Devin. 179 00:08:44,480 --> 00:08:48,200 Speaker 1: So we're trying to figure out why the hell headlights 180 00:08:48,200 --> 00:08:50,760 Speaker 1: seem to be so bright and why is there so 181 00:08:50,880 --> 00:08:53,480 Speaker 1: much glare when we're driving on the roads at night. 182 00:08:54,280 --> 00:08:58,360 Speaker 1: So I spoke with one of the industries leading car 183 00:08:58,480 --> 00:09:03,040 Speaker 1: lighting experts. So can I have you just start by 184 00:09:03,040 --> 00:09:03,959 Speaker 1: introducing yourself. 185 00:09:05,160 --> 00:09:08,200 Speaker 8: I'm Daniel Stern. I am the chief editor of Driving 186 00:09:08,280 --> 00:09:13,040 Speaker 8: Vision News, which is the global vehicle lighting world's technical 187 00:09:13,080 --> 00:09:14,320 Speaker 8: and trade journal of record. 188 00:09:14,520 --> 00:09:18,440 Speaker 1: He first realized his fascination with headlights when he was 189 00:09:18,480 --> 00:09:19,160 Speaker 1: seven years. 190 00:09:18,960 --> 00:09:21,480 Speaker 8: Old and my father was driving me somewhere after dark. 191 00:09:21,520 --> 00:09:24,959 Speaker 8: I think it was maybe like a like a musical presentation, 192 00:09:25,280 --> 00:09:29,320 Speaker 8: was in first or second grade, and he showed me 193 00:09:29,400 --> 00:09:31,600 Speaker 8: how there was a low beam for when there were 194 00:09:31,600 --> 00:09:33,920 Speaker 8: other cars around, and high beam for when the road 195 00:09:34,000 --> 00:09:35,080 Speaker 8: was clear, when it was empty. 196 00:09:35,800 --> 00:09:37,360 Speaker 6: So that was the root of it. 197 00:09:37,559 --> 00:09:41,160 Speaker 8: And then many years later I went off to school 198 00:09:41,160 --> 00:09:44,520 Speaker 8: in dark rainy Oregon at the University of Oregon, and 199 00:09:44,679 --> 00:09:47,000 Speaker 8: it seemed to me that I really could not see 200 00:09:47,120 --> 00:09:48,800 Speaker 8: as well as I thought I should be able to 201 00:09:48,880 --> 00:09:51,240 Speaker 8: when I was driving after dark, and so I started 202 00:09:51,480 --> 00:09:55,000 Speaker 8: sort of poking around into how headlamps work and you know, 203 00:09:55,040 --> 00:09:56,959 Speaker 8: maybe how they don't work. Around that time, I made 204 00:09:57,040 --> 00:09:59,240 Speaker 8: my first trip to Europe and I saw that they 205 00:09:59,240 --> 00:10:01,600 Speaker 8: did a whole lot of things differently with car lighting, 206 00:10:02,360 --> 00:10:05,719 Speaker 8: and so the interest took hold, and I transferred to 207 00:10:05,720 --> 00:10:09,160 Speaker 8: the University of Michigan, where at that time, the University 208 00:10:09,200 --> 00:10:14,360 Speaker 8: of Michigan Transportation Research Institute had a terrific library full 209 00:10:14,400 --> 00:10:17,320 Speaker 8: of decades worth of research, not only about lighting, but 210 00:10:17,440 --> 00:10:20,000 Speaker 8: lighting was a lot of what they did, and so 211 00:10:20,040 --> 00:10:25,040 Speaker 8: I would spend hours in this library just systematically devouring 212 00:10:25,320 --> 00:10:27,480 Speaker 8: these decades worth of research, and then i'd take the 213 00:10:27,480 --> 00:10:30,440 Speaker 8: elevator up to the second or third floor and ask 214 00:10:30,600 --> 00:10:32,760 Speaker 8: questions of the researchers who were working up there. They 215 00:10:32,760 --> 00:10:35,160 Speaker 8: were very patient with me, and so that was sort 216 00:10:35,160 --> 00:10:38,439 Speaker 8: of my three year long independent study on vehicle lighting 217 00:10:38,760 --> 00:10:42,119 Speaker 8: right at one of the world's foremost research institutes. 218 00:10:42,160 --> 00:10:47,240 Speaker 1: For it, to be honest, I thought the solution air 219 00:10:47,280 --> 00:10:49,920 Speaker 1: would be pretty simple, just like turn down the LED 220 00:10:50,040 --> 00:10:53,080 Speaker 1: lights and then you'll get rid of glare. But after 221 00:10:53,200 --> 00:10:55,440 Speaker 1: talking to Daniel over the last couple of weeks, it 222 00:10:55,520 --> 00:10:58,360 Speaker 1: turns out this issue is way more complicated than any 223 00:10:58,440 --> 00:11:01,760 Speaker 1: of us anticipated in and wide so complicated. You have 224 00:11:01,800 --> 00:11:03,880 Speaker 1: to know some of the recent advancements we've made of 225 00:11:04,080 --> 00:11:05,239 Speaker 1: car aliding technology. 226 00:11:05,480 --> 00:11:09,079 Speaker 8: Starting in nineteen forty, all vehicles in the United States 227 00:11:09,240 --> 00:11:11,640 Speaker 8: had what are called sealed beam headlamps. 228 00:11:11,679 --> 00:11:14,880 Speaker 1: There for our purposes, we'll fast forward to the nineties. 229 00:11:15,600 --> 00:11:19,240 Speaker 8: In the mid nineties, high intensity discharged headlamps came along. 230 00:11:19,400 --> 00:11:21,560 Speaker 8: Now you can have three times more light within the 231 00:11:21,559 --> 00:11:25,280 Speaker 8: headlight beam, and the light color was it had a 232 00:11:25,360 --> 00:11:27,800 Speaker 8: radical shift from sort of a warm white to a 233 00:11:27,840 --> 00:11:30,480 Speaker 8: cold white, a bluish white, and that started that There 234 00:11:30,559 --> 00:11:33,800 Speaker 8: was a spike in glare complaints when that happened, and 235 00:11:33,920 --> 00:11:36,800 Speaker 8: the official response was, yeah, you'll get used to it. 236 00:11:36,960 --> 00:11:39,319 Speaker 6: You're only noticing it because they look different. Just look 237 00:11:39,320 --> 00:11:40,120 Speaker 6: away from the glare. 238 00:11:40,520 --> 00:11:44,520 Speaker 8: And then in the early to mid two thousands, LEDs 239 00:11:45,000 --> 00:11:47,920 Speaker 8: advanced to the point where we could use them for headlamps, 240 00:11:48,520 --> 00:11:54,280 Speaker 8: and so headlamps once again grew brighter and bluer, and 241 00:11:54,320 --> 00:11:57,520 Speaker 8: the glare complaints spiked, and the same response sort of 242 00:11:57,559 --> 00:11:59,400 Speaker 8: came down. Yeah, you'll get used to it. It's not 243 00:11:59,400 --> 00:12:02,960 Speaker 8: really hurting out, you know, it's just just look away 244 00:12:02,960 --> 00:12:03,520 Speaker 8: from the glare. 245 00:12:04,040 --> 00:12:07,440 Speaker 3: And today our most headlamps led. 246 00:12:07,800 --> 00:12:11,200 Speaker 8: Yeah, and new cars are pretty much all designed new 247 00:12:11,200 --> 00:12:13,920 Speaker 8: cars trucks as these new road going vehicles are pretty 248 00:12:14,000 --> 00:12:16,720 Speaker 8: much all designed with LED headlamps right from the start. 249 00:12:18,840 --> 00:12:21,640 Speaker 1: All right, So for our question, why is headlight glayer 250 00:12:21,720 --> 00:12:26,840 Speaker 1: so bad? The first culprit LEDs. So the first question 251 00:12:26,960 --> 00:12:30,760 Speaker 1: I had for him is our LED lights just brighter? 252 00:12:30,800 --> 00:12:32,720 Speaker 3: Right? Is that the issue? The lights are just brighter? 253 00:12:33,160 --> 00:12:36,319 Speaker 1: So this may be, you know, a dumb and obvious question, 254 00:12:36,760 --> 00:12:40,360 Speaker 1: but our LED headlamps technically brighter. 255 00:12:40,600 --> 00:12:41,480 Speaker 6: Well, it's a little. 256 00:12:41,320 --> 00:12:43,920 Speaker 8: Difficult to answer that question has asked because this isn't 257 00:12:44,000 --> 00:12:46,800 Speaker 8: really when you say brighter and you think of it 258 00:12:46,800 --> 00:12:48,520 Speaker 8: in terms like you're in your dining room and you 259 00:12:48,559 --> 00:12:51,320 Speaker 8: turn the dimmer up or down to make the dining 260 00:12:51,360 --> 00:12:54,360 Speaker 8: table brighter or dimmer, this is a lot more complex 261 00:12:54,400 --> 00:12:57,000 Speaker 8: than that. A headlight beam isn't just a floodlight or 262 00:12:57,040 --> 00:12:59,600 Speaker 8: a spotlight that you know that is brighter or dimmer. 263 00:12:59,600 --> 00:13:04,520 Speaker 8: It's actually a very complex pattern of light with areas 264 00:13:04,559 --> 00:13:07,959 Speaker 8: defined by what are called test points. A test point 265 00:13:08,120 --> 00:13:12,559 Speaker 8: might have a minimum required intensity, a maximum required intensity, 266 00:13:12,679 --> 00:13:16,000 Speaker 8: or both, and a low beam in particular is super 267 00:13:16,040 --> 00:13:18,520 Speaker 8: complex because you need to have high intensity for the 268 00:13:18,600 --> 00:13:21,520 Speaker 8: driver to see far enough down the road right next 269 00:13:21,520 --> 00:13:24,520 Speaker 8: to low intensity to protect other drivers on the road 270 00:13:24,520 --> 00:13:25,040 Speaker 8: from glare. 271 00:13:25,600 --> 00:13:27,760 Speaker 1: So I'm actually gonna share this video if you guess 272 00:13:29,640 --> 00:13:32,719 Speaker 1: that'll sort of exemplify what he's saying. 273 00:13:32,480 --> 00:13:34,559 Speaker 4: Here, Great, because that didn't make any sense to me. 274 00:13:36,000 --> 00:13:37,880 Speaker 1: Or yeah, when it's shining on the wall to a 275 00:13:37,880 --> 00:13:40,600 Speaker 1: little bit before, just like pause it on that, Okay, 276 00:13:40,800 --> 00:13:42,280 Speaker 1: I mean trying to break in this down because I 277 00:13:42,320 --> 00:13:44,600 Speaker 1: know this is kind of hard to visualize, especially for 278 00:13:44,679 --> 00:13:47,960 Speaker 1: a podcast. But imagine you're shining your headlights in a 279 00:13:48,000 --> 00:13:52,160 Speaker 1: garage on a wall. You're probably thinking of something similar 280 00:13:52,240 --> 00:13:55,760 Speaker 1: to a flashlight, right, like pretty even light, maybe a 281 00:13:55,840 --> 00:13:59,880 Speaker 1: little bit more oval or rectangular, because these are headlamps 282 00:14:00,080 --> 00:14:03,800 Speaker 1: versus a flashlight. But that's not really the case. So 283 00:14:03,920 --> 00:14:07,480 Speaker 1: what do they actually look like? All right, So let's 284 00:14:07,520 --> 00:14:10,960 Speaker 1: imagine for a second and stick with me that you're 285 00:14:11,240 --> 00:14:16,520 Speaker 1: some abstract artists and you're painting Luigi Manngioni's latest mugshot. 286 00:14:16,840 --> 00:14:19,080 Speaker 1: Because you're an abstract artist, you're not just gonna draw 287 00:14:19,120 --> 00:14:23,200 Speaker 1: straight lines and fill on the eyebrows completely. Instead, you're 288 00:14:23,240 --> 00:14:25,640 Speaker 1: gonna put maybe a blob of paint here, maybe no 289 00:14:25,760 --> 00:14:28,280 Speaker 1: paint on this area of the eyebrow, maybe a little 290 00:14:28,280 --> 00:14:31,440 Speaker 1: bit of paint down below. And that's how the headlight 291 00:14:31,520 --> 00:14:34,760 Speaker 1: beam operates as well. There are parts in the beam 292 00:14:34,800 --> 00:14:37,360 Speaker 1: that have really intense light, and there are parts within 293 00:14:37,400 --> 00:14:39,960 Speaker 1: the beam that have almost no light at all. And 294 00:14:40,000 --> 00:14:45,320 Speaker 1: his varying degree of light intensity is really purposeful. The 295 00:14:45,400 --> 00:14:49,240 Speaker 1: headlight is designed so that the person driving has maximum 296 00:14:49,360 --> 00:14:52,800 Speaker 1: visibility but limiting the amount of light that's being thrown 297 00:14:53,240 --> 00:14:55,960 Speaker 1: to other people from oncoming traffic. 298 00:14:56,760 --> 00:15:00,640 Speaker 4: Oh okay, so the gradient is like you're on one 299 00:15:00,640 --> 00:15:03,160 Speaker 4: side of the highway driving north, the other side of 300 00:15:03,160 --> 00:15:07,200 Speaker 4: the highways driving south, and the gradient is blocking people 301 00:15:07,240 --> 00:15:09,600 Speaker 4: who are going south from like being blinded by your 302 00:15:09,640 --> 00:15:10,400 Speaker 4: light exactly. 303 00:15:10,640 --> 00:15:12,640 Speaker 7: Yeah, because if it was all that intensity, it would 304 00:15:12,640 --> 00:15:14,560 Speaker 7: be really impossible to see. 305 00:15:14,640 --> 00:15:16,000 Speaker 6: So it's really very complex. 306 00:15:16,520 --> 00:15:21,320 Speaker 8: That said. Yes, in a word, yes, today's headlamps are 307 00:15:21,920 --> 00:15:24,320 Speaker 8: their higher intensity, They put a lot more light out, 308 00:15:24,360 --> 00:15:26,520 Speaker 8: They put out much wider beams. 309 00:15:26,360 --> 00:15:29,240 Speaker 1: For our purposes, we'll say they're brighter, although technically, you know, 310 00:15:29,480 --> 00:15:31,040 Speaker 1: I don't want I don't I don't want Daniel to 311 00:15:31,080 --> 00:15:31,480 Speaker 1: yell at me. 312 00:15:31,560 --> 00:15:33,080 Speaker 3: Yeah, it's not so simple. 313 00:15:34,240 --> 00:15:34,960 Speaker 5: They're more intense. 314 00:15:35,040 --> 00:15:36,800 Speaker 3: Is that a good yes, Yeah, we'll say intense. 315 00:15:36,800 --> 00:15:39,200 Speaker 1: I don't know if people be okay with that. And then 316 00:15:39,760 --> 00:15:43,480 Speaker 1: there's another reason why they appear so bright. You talk 317 00:15:43,520 --> 00:15:48,120 Speaker 1: about how with led lights it's more intensity from a 318 00:15:48,280 --> 00:15:50,960 Speaker 1: smaller I don't know with the technical term for it, 319 00:15:51,000 --> 00:15:53,000 Speaker 1: but like a smaller opening, right, it's coming from a 320 00:15:53,040 --> 00:15:53,720 Speaker 1: smaller space. 321 00:15:53,800 --> 00:15:54,000 Speaker 6: Yeah. 322 00:15:54,040 --> 00:15:59,240 Speaker 8: The technical term is luminance, and in real simple words, 323 00:15:59,280 --> 00:16:03,440 Speaker 8: it means how right something looks. You can also think 324 00:16:03,480 --> 00:16:05,880 Speaker 8: of it as light density. If you have a certain 325 00:16:05,920 --> 00:16:10,440 Speaker 8: amount of light coming from a small area, uh, it's 326 00:16:10,600 --> 00:16:13,320 Speaker 8: going to look brighter than that very same amount of 327 00:16:13,400 --> 00:16:18,000 Speaker 8: light coming from a large area because that given amount 328 00:16:18,040 --> 00:16:21,240 Speaker 8: of light with a large area, it's spread over a 329 00:16:21,320 --> 00:16:25,440 Speaker 8: over a big surface, whereas with a small area it's 330 00:16:25,480 --> 00:16:30,440 Speaker 8: sort of condensed into a point instead of a large surface. 331 00:16:31,440 --> 00:16:32,880 Speaker 8: You can sort of you can think of it as 332 00:16:33,440 --> 00:16:36,720 Speaker 8: you say, you're putting a certain amount of water through 333 00:16:36,720 --> 00:16:37,200 Speaker 8: a hose. 334 00:16:37,400 --> 00:16:38,080 Speaker 6: If you have a. 335 00:16:38,040 --> 00:16:40,000 Speaker 8: Tiny little hole at the end of the nozzle you're 336 00:16:40,040 --> 00:16:41,520 Speaker 8: going to have like a jet stream. 337 00:16:41,600 --> 00:16:43,760 Speaker 6: You can you can powerwash. 338 00:16:43,280 --> 00:16:46,920 Speaker 8: Your driveway if if you have a big sort of 339 00:16:46,960 --> 00:16:50,240 Speaker 8: a big watering looks like the end of a watering can, 340 00:16:50,320 --> 00:16:52,920 Speaker 8: sprinkling end of a watering can, well you'll have a 341 00:16:53,000 --> 00:16:55,360 Speaker 8: nice sort of gentle rain shower, same amount of water, 342 00:16:55,560 --> 00:16:58,520 Speaker 8: but it's but it's behaving very differently and light does 343 00:16:58,560 --> 00:16:59,200 Speaker 8: the same thing. 344 00:17:00,000 --> 00:17:02,480 Speaker 1: It's a really good visual way of thinking about it, 345 00:17:02,520 --> 00:17:05,399 Speaker 1: all right. So that's the second reason why LED's a 346 00:17:05,480 --> 00:17:06,919 Speaker 1: pair rider is because the light. 347 00:17:06,840 --> 00:17:08,080 Speaker 3: Is coming from a smaller opening. 348 00:17:08,480 --> 00:17:15,080 Speaker 1: And then the last culprit is the color blue. 349 00:17:15,119 --> 00:17:17,720 Speaker 8: This is really interesting, actually, there's a lot of really 350 00:17:17,760 --> 00:17:21,360 Speaker 8: sturdy science showing that for any given intensity white light 351 00:17:21,400 --> 00:17:26,040 Speaker 8: that contains more blue creates much greater discomfort clayer than 352 00:17:26,119 --> 00:17:28,480 Speaker 8: light that has less blue. So with that on the table, 353 00:17:29,040 --> 00:17:32,800 Speaker 8: it's been found that just to put rough numbers on it, 354 00:17:33,040 --> 00:17:37,720 Speaker 8: if you have two headlamps that measure say a thousand candela, 355 00:17:38,040 --> 00:17:39,040 Speaker 8: the candela. 356 00:17:38,680 --> 00:17:41,760 Speaker 6: Being the measurement unit for intensity. 357 00:17:41,320 --> 00:17:44,960 Speaker 8: Two headlamps putting a thousand candela towards an oncoming driver's eyes. 358 00:17:45,480 --> 00:17:47,520 Speaker 8: One of the headlamps is a halogen lamp and it 359 00:17:47,560 --> 00:17:50,520 Speaker 8: has sort of a yellowish white, warm white light color. 360 00:17:51,080 --> 00:17:53,400 Speaker 8: The other headlamp is an LED. It has a cold white, 361 00:17:53,440 --> 00:17:56,000 Speaker 8: a bluish white light color. In order for those two 362 00:17:56,040 --> 00:17:58,840 Speaker 8: headlamps to feel the same to the oncoming driver in 363 00:17:58,880 --> 00:18:02,280 Speaker 8: terms of how they experience the glare, the halogen headlamp 364 00:18:02,359 --> 00:18:05,920 Speaker 8: would have to be producing at least sixteen hundred candela 365 00:18:06,280 --> 00:18:10,000 Speaker 8: to match the feeling of glare created by the LED headlamp. 366 00:18:10,040 --> 00:18:13,040 Speaker 8: And the kicker of that is the sort of the punchline, 367 00:18:13,640 --> 00:18:15,560 Speaker 8: maybe it's a punch in the gut or a punch 368 00:18:15,560 --> 00:18:19,560 Speaker 8: in the eyes, is that you don't get sixty percent 369 00:18:20,080 --> 00:18:22,600 Speaker 8: better seeing with the bluer light. You don't get any 370 00:18:22,920 --> 00:18:25,639 Speaker 8: better seeing with the bluer light. You just get you 371 00:18:26,359 --> 00:18:29,360 Speaker 8: do have a sort of a feeling as though it's brighter, 372 00:18:30,160 --> 00:18:33,679 Speaker 8: and you have this much greater sensation of glare caused 373 00:18:33,680 --> 00:18:34,480 Speaker 8: by the bluer light. 374 00:18:37,080 --> 00:18:39,720 Speaker 1: This was really crazy to me, right, because our eyes 375 00:18:39,720 --> 00:18:43,080 Speaker 1: are more sensitive to blue light, so it appears brighter 376 00:18:43,080 --> 00:18:45,760 Speaker 1: to us, but it actually doesn't help us see any better, 377 00:18:46,280 --> 00:18:48,159 Speaker 1: and then it just causes more glare when we're on 378 00:18:48,200 --> 00:18:48,520 Speaker 1: the road. 379 00:18:49,080 --> 00:18:54,080 Speaker 5: Well, so then why why do we have them? 380 00:18:54,240 --> 00:18:55,160 Speaker 3: Because it looks cool. 381 00:18:55,200 --> 00:18:57,240 Speaker 5: Okay, yeah, that's true. 382 00:19:04,119 --> 00:19:07,639 Speaker 1: So let's recap for LEDs. Yes, they're more powerful than 383 00:19:07,680 --> 00:19:10,880 Speaker 1: previous headlamps. They are here to be brighter because they're 384 00:19:10,880 --> 00:19:12,040 Speaker 1: coming from smaller openings. 385 00:19:12,680 --> 00:19:12,800 Speaker 2: Uh. 386 00:19:13,000 --> 00:19:16,000 Speaker 1: And then we got blue, which creates more glayer. And 387 00:19:16,040 --> 00:19:19,239 Speaker 1: it also brings us to our second culprit, which is 388 00:19:19,320 --> 00:19:20,800 Speaker 1: called headlight. 389 00:19:20,520 --> 00:19:23,359 Speaker 3: Aim hhmm you know what that is. 390 00:19:23,800 --> 00:19:26,120 Speaker 1: You don't want to be headlight aim. 391 00:19:26,720 --> 00:19:27,760 Speaker 4: I can guess if you want. 392 00:19:27,840 --> 00:19:28,680 Speaker 3: And yeah, I guess. 393 00:19:30,480 --> 00:19:34,080 Speaker 4: I've noticed some headlights have like lids on them, all right. 394 00:19:34,160 --> 00:19:36,840 Speaker 7: Is it like the direct spot where it's most intense 395 00:19:38,040 --> 00:19:39,400 Speaker 7: closer closer. 396 00:19:40,600 --> 00:19:43,560 Speaker 3: Yeah, you guys didn't do the research. 397 00:19:45,520 --> 00:19:48,560 Speaker 5: What I looked like a car lighting specialist, all right. 398 00:19:48,760 --> 00:19:51,080 Speaker 1: So we talked about blue. We talked about how people 399 00:19:51,600 --> 00:19:52,880 Speaker 1: like the look of the blue lights. 400 00:19:52,960 --> 00:19:53,080 Speaker 8: Right. 401 00:19:53,119 --> 00:19:55,800 Speaker 1: A lot of people with older cars will go out 402 00:19:55,840 --> 00:19:59,439 Speaker 1: and buy LED light bulbs and put them in their 403 00:19:59,480 --> 00:19:59,960 Speaker 1: older cars. 404 00:20:00,119 --> 00:20:00,359 Speaker 2: Hmm. 405 00:20:01,040 --> 00:20:03,360 Speaker 4: I remember that with like James Bond movies, they made 406 00:20:03,400 --> 00:20:05,760 Speaker 4: it a point for blue lights in the head. 407 00:20:05,720 --> 00:20:06,600 Speaker 3: Blue lights, right. 408 00:20:06,680 --> 00:20:10,119 Speaker 1: So Daniel said, there's a very big problem with this, 409 00:20:10,560 --> 00:20:14,440 Speaker 1: which is the LED lights are not designed to go 410 00:20:14,480 --> 00:20:15,520 Speaker 1: in these older cars. 411 00:20:15,800 --> 00:20:18,040 Speaker 8: You can go on Amazon eBay. You can walk into 412 00:20:18,080 --> 00:20:21,240 Speaker 8: parts stores all over the place you can buy these 413 00:20:21,960 --> 00:20:26,840 Speaker 8: LED bulbs claiming to update your halogen headlamps. In the 414 00:20:26,960 --> 00:20:30,680 Speaker 8: United States, the major brands market them with a nudge 415 00:20:30,680 --> 00:20:32,399 Speaker 8: in a wink, saying, you know, these are only for 416 00:20:32,480 --> 00:20:37,000 Speaker 8: fog lamps. Don't put them in your headlamps, right because 417 00:20:38,000 --> 00:20:40,800 Speaker 8: fog light bulbs are not regulated in the United States 418 00:20:40,800 --> 00:20:45,000 Speaker 8: where head light bulbs are. Of course, fog lamps and 419 00:20:45,040 --> 00:20:47,240 Speaker 8: headlamps use a lot of the same types of bulbs, 420 00:20:48,320 --> 00:20:50,399 Speaker 8: and people are you know, people put them in their 421 00:20:50,400 --> 00:20:52,159 Speaker 8: head lamps and they think, oh, hey, well now I've 422 00:20:52,200 --> 00:20:53,480 Speaker 8: got led headlamps. 423 00:20:53,080 --> 00:20:55,480 Speaker 6: And look how bright they are. It's a different kind 424 00:20:55,480 --> 00:20:55,760 Speaker 6: of legs. 425 00:20:55,840 --> 00:20:58,840 Speaker 8: It's very much like putting on somebody else's eyeglasses. You 426 00:20:58,920 --> 00:21:02,000 Speaker 8: might find someone else's eyeglasses that look terrific on your face, 427 00:21:02,720 --> 00:21:06,240 Speaker 8: but because the lenses are not for your eyes, you're 428 00:21:06,280 --> 00:21:07,919 Speaker 8: not going to see properly, and you're going to give 429 00:21:07,960 --> 00:21:10,200 Speaker 8: yourself a headache and you're going to injure your eyes 430 00:21:10,280 --> 00:21:13,520 Speaker 8: doing it. So in the same way, you put LED 431 00:21:13,640 --> 00:21:17,240 Speaker 8: bulbs in a halogen headlamp, you might think they look 432 00:21:17,320 --> 00:21:19,720 Speaker 8: terrific and they have that blue white appearance just like 433 00:21:19,760 --> 00:21:22,200 Speaker 8: the newer cars, and you might even think you can 434 00:21:22,200 --> 00:21:26,040 Speaker 8: see better, but in fact the light distribution is all 435 00:21:26,080 --> 00:21:28,760 Speaker 8: screwed up. You've got way too much light in places 436 00:21:28,760 --> 00:21:31,200 Speaker 8: where that's dangerous, you've got not enough light in places 437 00:21:31,240 --> 00:21:33,600 Speaker 8: where that's dangerous. And most of all, you've got a 438 00:21:33,600 --> 00:21:37,560 Speaker 8: whole lot more glare. So and it's very poorly policed 439 00:21:37,880 --> 00:21:42,400 Speaker 8: in most of North America. So you know, these things 440 00:21:42,440 --> 00:21:46,719 Speaker 8: widely available and nobody's giving tickets. Well, yeah, that's a 441 00:21:46,760 --> 00:21:48,040 Speaker 8: major source of glare. 442 00:21:47,720 --> 00:21:48,200 Speaker 3: On the road. 443 00:21:48,520 --> 00:21:51,720 Speaker 1: Back on this alignment bit, right, so people are getting 444 00:21:52,440 --> 00:21:55,760 Speaker 1: bulbs that aren't meant for their cars. Is there also 445 00:21:56,080 --> 00:22:00,119 Speaker 1: just an issue with alignment period with people who have 446 00:22:00,240 --> 00:22:03,240 Speaker 1: led headlamps initially, very much so. 447 00:22:03,359 --> 00:22:06,639 Speaker 8: And it's not just with people who have legitimate lab headlamps. 448 00:22:07,760 --> 00:22:12,960 Speaker 8: Headlamp aim is, by a giant margin, the primary main 449 00:22:13,040 --> 00:22:15,600 Speaker 8: determinant not only of how well the driver can see, 450 00:22:15,600 --> 00:22:19,040 Speaker 8: but how much glear they're throwing around. And headlamps, as 451 00:22:19,040 --> 00:22:23,320 Speaker 8: they have evolved over the last five six decades, as 452 00:22:23,320 --> 00:22:26,560 Speaker 8: they've grown more and more intense, they've grown more and 453 00:22:26,640 --> 00:22:28,160 Speaker 8: more sensitive to miss aim. 454 00:22:28,480 --> 00:22:30,879 Speaker 1: This could be from something small like say you have 455 00:22:30,920 --> 00:22:33,000 Speaker 1: a lot of people in your car, so you know, 456 00:22:33,119 --> 00:22:35,879 Speaker 1: the car shifts a little bit, so not the lights aren't. 457 00:22:35,600 --> 00:22:36,760 Speaker 3: Exactly where you're supposed to be. 458 00:22:37,160 --> 00:22:39,280 Speaker 1: It could be from when you're driving, if you hit 459 00:22:39,320 --> 00:22:43,320 Speaker 1: a bump, if the road is angled a little bit, 460 00:22:43,640 --> 00:22:45,520 Speaker 1: or it could be something that you know over time, 461 00:22:45,560 --> 00:22:47,040 Speaker 1: your headlights shift. 462 00:22:46,960 --> 00:22:49,280 Speaker 8: In the past. You know, a headlamp of the nineteen 463 00:22:49,320 --> 00:22:53,439 Speaker 8: sixties or seventies, maybe eighties, if it was aimed you know, 464 00:22:53,560 --> 00:22:56,399 Speaker 8: a degree or two this way or that can't really 465 00:22:57,119 --> 00:22:59,560 Speaker 8: exert a huge change in the amount of light that 466 00:22:59,600 --> 00:23:01,960 Speaker 8: the driver had to see on the road or the 467 00:23:02,000 --> 00:23:02,880 Speaker 8: amount of glare they. 468 00:23:02,760 --> 00:23:05,560 Speaker 6: Were throwing around. Might look a little brighter. 469 00:23:05,280 --> 00:23:07,960 Speaker 8: As it passes you, but it's still a low beam headline. 470 00:23:08,040 --> 00:23:11,159 Speaker 8: But a modern headlight beam which is very wide and 471 00:23:11,240 --> 00:23:13,080 Speaker 8: has a sharp cut off at the top. 472 00:23:12,920 --> 00:23:14,560 Speaker 6: Of the low beam, where below this. 473 00:23:14,520 --> 00:23:17,760 Speaker 8: Cutoff line is very high intensity and above the cut 474 00:23:17,760 --> 00:23:21,000 Speaker 8: off line is low intensity is dark. Low beams have 475 00:23:21,119 --> 00:23:25,159 Speaker 8: such high intensity below that cutoff, the low beam aimed 476 00:23:25,560 --> 00:23:28,840 Speaker 8: a degree or to too high could easily qualify as 477 00:23:28,840 --> 00:23:33,760 Speaker 8: a high beam. 478 00:23:34,000 --> 00:23:36,320 Speaker 1: But that explains why we were saying. When the first 479 00:23:36,359 --> 00:23:39,120 Speaker 1: time we talked right it felt like, why are people 480 00:23:39,200 --> 00:23:42,480 Speaker 1: driving around with their high beams on. Right, It's like, oh, no, 481 00:23:42,920 --> 00:23:45,600 Speaker 1: they're not. Their alignment is just off and the low 482 00:23:45,640 --> 00:23:48,199 Speaker 1: beam now is you know, so much more advanced than 483 00:23:48,240 --> 00:23:50,080 Speaker 1: it was in the past that it feels like people 484 00:23:50,119 --> 00:23:51,960 Speaker 1: have their high beams on when they're driving at you. 485 00:23:52,840 --> 00:23:57,399 Speaker 4: Wow, this is this is nuts. That's huge because I 486 00:23:57,440 --> 00:24:00,159 Speaker 4: had no faith in humanity. 487 00:23:59,600 --> 00:24:02,320 Speaker 3: Really thought everyone was just driving around. 488 00:24:02,800 --> 00:24:05,480 Speaker 4: I thought people were just like their eyesight was getting 489 00:24:05,480 --> 00:24:07,800 Speaker 4: worse to something and they're just ripping the lights on 490 00:24:08,600 --> 00:24:09,120 Speaker 4: like every time. 491 00:24:09,160 --> 00:24:09,919 Speaker 5: That's what it felt like. 492 00:24:10,040 --> 00:24:13,959 Speaker 1: Yeah, feels like headlight aim is not part of the 493 00:24:14,000 --> 00:24:18,200 Speaker 1: inspection process. So when you go get your car inspected, 494 00:24:18,320 --> 00:24:20,359 Speaker 1: headlight aim is not something that they're checking. 495 00:24:21,119 --> 00:24:26,159 Speaker 8: Yeah, the the aim is super important, and unfortunately it 496 00:24:26,280 --> 00:24:29,160 Speaker 8: is almost impossible in North America. We just don't pay 497 00:24:29,160 --> 00:24:33,080 Speaker 8: attention to headlight aim. It's almost impossible anywhere in North America. 498 00:24:33,520 --> 00:24:35,680 Speaker 8: Even if you're standing there with a fistful of cash 499 00:24:35,680 --> 00:24:37,800 Speaker 8: and saying, somebody, take my money and aim my head 500 00:24:37,840 --> 00:24:40,320 Speaker 8: lamps correctly, it's really hard to get it done. 501 00:24:40,400 --> 00:24:43,040 Speaker 5: People had to auto shop aren't trained for that. 502 00:24:43,200 --> 00:24:48,520 Speaker 1: No, it's a really request exactly, at least in the US. 503 00:24:48,280 --> 00:24:50,880 Speaker 4: And some states you don't get your car inspected at all, 504 00:24:51,040 --> 00:24:52,600 Speaker 4: like the Great State of Ohio. 505 00:24:52,800 --> 00:24:56,159 Speaker 1: That's why people get uh, the car is registrated in Ohio, right, 506 00:24:56,200 --> 00:24:57,600 Speaker 1: the shitty cars really? 507 00:24:57,680 --> 00:24:58,000 Speaker 3: Yeah? 508 00:24:58,080 --> 00:24:58,720 Speaker 4: Oh my god. 509 00:25:04,680 --> 00:25:07,520 Speaker 1: Okay, So to recap, because led have lamps have such 510 00:25:07,560 --> 00:25:10,440 Speaker 1: a small margin of error before they create a ton 511 00:25:10,480 --> 00:25:14,000 Speaker 1: of glare, alignment is super important. But in the US 512 00:25:14,280 --> 00:25:18,920 Speaker 1: this is not something we traditionally care about. And then, lastly, 513 00:25:19,280 --> 00:25:22,880 Speaker 1: so our last rezone. Why is glare more intense now 514 00:25:22,960 --> 00:25:24,639 Speaker 1: than it seems like it used to be? 515 00:25:25,480 --> 00:25:26,240 Speaker 3: Part of it is. 516 00:25:26,280 --> 00:25:30,879 Speaker 8: Us as we get older, and this is really unfortunate. 517 00:25:30,880 --> 00:25:34,439 Speaker 8: This really sucks. As we get older, we need a 518 00:25:34,480 --> 00:25:37,560 Speaker 8: lot more light to see any given thing, and at 519 00:25:37,560 --> 00:25:39,600 Speaker 8: the same time, we get a whole lot more sensitive 520 00:25:39,600 --> 00:25:40,000 Speaker 8: to glare. 521 00:25:40,840 --> 00:25:41,960 Speaker 6: So when we're. 522 00:25:41,800 --> 00:25:45,080 Speaker 8: Sixty, we need about triple the light that we needed 523 00:25:45,119 --> 00:25:47,360 Speaker 8: when we were twenty to see any given thing under 524 00:25:47,400 --> 00:25:52,720 Speaker 8: any given conditions at night, and we are massively more 525 00:25:52,760 --> 00:25:57,000 Speaker 8: sensitive to glare. So, you know, if only one of 526 00:25:57,040 --> 00:25:59,200 Speaker 8: those two things were true, it would be really easy 527 00:25:59,240 --> 00:26:02,160 Speaker 8: to fix. But both of them are true, and so 528 00:26:02,800 --> 00:26:05,200 Speaker 8: if you address the one thing, you aggravate the other. 529 00:26:05,320 --> 00:26:07,720 Speaker 5: So we're more sensitive to light, yes, and need more, 530 00:26:07,720 --> 00:26:10,080 Speaker 5: I need it more. Yes, it's not a good place 531 00:26:10,119 --> 00:26:10,320 Speaker 5: to be. 532 00:26:10,640 --> 00:26:13,399 Speaker 3: Is not a good place going to be. 533 00:26:13,760 --> 00:26:19,000 Speaker 1: This dichotomy sort of speaks to the really, really tough 534 00:26:19,040 --> 00:26:23,280 Speaker 1: situation that the United States federal government finds itself in 535 00:26:23,359 --> 00:26:30,439 Speaker 1: right now. They have to balance people seeing with also 536 00:26:30,520 --> 00:26:34,400 Speaker 1: thinking about lair, which makes it harder for people to see. 537 00:26:35,240 --> 00:26:39,639 Speaker 1: So I was curious, like, are is somebody working on this, 538 00:26:39,840 --> 00:26:42,240 Speaker 1: you know, someone in the Trump illustration, like going to 539 00:26:42,320 --> 00:26:44,560 Speaker 1: create a rule that your headlights can be only but 540 00:26:44,800 --> 00:26:48,199 Speaker 1: so bright because you know there's so much claire in 541 00:26:49,080 --> 00:26:50,399 Speaker 1: it's causing a huge issue. 542 00:26:50,840 --> 00:26:53,280 Speaker 3: And he said that something like. 543 00:26:53,359 --> 00:26:57,280 Speaker 1: Lair is both hard to define and then also hard 544 00:26:57,320 --> 00:26:57,840 Speaker 1: to make. 545 00:26:57,720 --> 00:26:59,840 Speaker 8: Rules for the fact is this is this is not 546 00:27:00,119 --> 00:27:05,240 Speaker 8: symmetrical safety situation. Yes, glare can be unsafe, absolutely no 547 00:27:05,320 --> 00:27:08,280 Speaker 8: debate about that, and reach sure can be uncomfortable, but. 548 00:27:08,600 --> 00:27:10,200 Speaker 6: It's not a one to one thing. 549 00:27:10,880 --> 00:27:16,720 Speaker 8: Unfortunately, up to a fairly large degree, more light from 550 00:27:16,760 --> 00:27:21,239 Speaker 8: the headlights means better safety, means less likelihood of a crash. 551 00:27:21,600 --> 00:27:24,840 Speaker 8: So let me sort of address how this knot is tied. 552 00:27:25,520 --> 00:27:29,360 Speaker 8: I think Unfortunately, for a long time, particularly in North America, 553 00:27:29,760 --> 00:27:32,680 Speaker 8: there's been a tendency for the official response to glare 554 00:27:32,720 --> 00:27:35,320 Speaker 8: complaints to be you'll get used to it or you won't, 555 00:27:35,320 --> 00:27:36,760 Speaker 8: but just look away from it, just deal with it, 556 00:27:36,800 --> 00:27:40,359 Speaker 8: grate your teeth. It's not actually a safety thing. We 557 00:27:40,400 --> 00:27:42,679 Speaker 8: think glair is bad on principle, we're going to regulate it. 558 00:27:42,680 --> 00:27:43,919 Speaker 6: Can't do that in North America. 559 00:27:43,960 --> 00:27:47,000 Speaker 8: You have to say, well, here is concrete proof of 560 00:27:47,080 --> 00:27:49,399 Speaker 8: the costs of glare in terms of the crashes that 561 00:27:49,480 --> 00:27:52,639 Speaker 8: it actually causes, and so can we can regulate to 562 00:27:52,680 --> 00:27:57,320 Speaker 8: the degree necessary to countervail those costs and that damage. 563 00:27:58,160 --> 00:28:03,040 Speaker 8: It's essentially impossible, and so that's why we have so 564 00:28:03,240 --> 00:28:06,920 Speaker 8: much less regulation of headlight glayer in North America than 565 00:28:07,000 --> 00:28:09,920 Speaker 8: they have in Europe and in Asia and Australia and 566 00:28:10,000 --> 00:28:12,639 Speaker 8: other countries that use a different regulatory system. 567 00:28:13,280 --> 00:28:19,240 Speaker 1: So you're saying that the National Highway Traffic Safety Administration, 568 00:28:19,480 --> 00:28:24,280 Speaker 1: so they have not addressed this glare because there's not 569 00:28:25,359 --> 00:28:28,480 Speaker 1: a lot of concrete sort of numbers that we have 570 00:28:28,680 --> 00:28:32,000 Speaker 1: that glare cause x amount of accidents. Therefore we need 571 00:28:32,040 --> 00:28:33,280 Speaker 1: to address it by doing this. 572 00:28:34,119 --> 00:28:35,240 Speaker 6: That's exactly right. 573 00:28:36,440 --> 00:28:40,480 Speaker 8: But it gets a lot more interesting than that, because 574 00:28:40,840 --> 00:28:44,960 Speaker 8: for most of the twentieth century from the dawn of 575 00:28:45,040 --> 00:28:50,360 Speaker 8: electric headlights on cars. Europe had much more stringent glare 576 00:28:50,400 --> 00:28:53,360 Speaker 8: control than the United States did. 577 00:28:54,280 --> 00:28:58,200 Speaker 1: Can Europe actually save us? We'll find out after the 578 00:28:58,240 --> 00:29:27,240 Speaker 1: break in Europe they have much more stringent their controls. Okay, 579 00:29:27,280 --> 00:29:30,240 Speaker 1: so here's three things that Europe does that we do 580 00:29:30,320 --> 00:29:36,800 Speaker 1: not do. Number one, so their headlight aim is much 581 00:29:36,880 --> 00:29:37,920 Speaker 1: lower than ours. 582 00:29:38,760 --> 00:29:42,560 Speaker 8: You're in your Honda Civic, You're in your Chevrolet Corvette. 583 00:29:42,560 --> 00:29:45,640 Speaker 8: You're in You're in a car. Well behind you is 584 00:29:45,680 --> 00:29:49,600 Speaker 8: a pickup trucker, an suv, and it's head lamps are right, 585 00:29:49,640 --> 00:29:51,280 Speaker 8: and they're way up in the air, and they're right 586 00:29:51,400 --> 00:29:55,640 Speaker 8: even with your car's mirrors. Yeah, you're gonna get blasted. 587 00:29:57,480 --> 00:30:00,840 Speaker 8: The rest of world regulations do two things to address that. 588 00:30:00,880 --> 00:30:04,080 Speaker 8: You can't you can't completely cure it because this is 589 00:30:04,160 --> 00:30:04,720 Speaker 8: just physics. 590 00:30:05,160 --> 00:30:07,800 Speaker 1: Yeah, some cars are taller than others. 591 00:30:08,480 --> 00:30:10,960 Speaker 8: Some cars are taller than others. The regulations in the 592 00:30:10,960 --> 00:30:14,360 Speaker 8: rest of the world do two things to limit that. 593 00:30:14,400 --> 00:30:19,680 Speaker 8: They have a lower maximum headlamp mounting hype and they 594 00:30:19,720 --> 00:30:22,160 Speaker 8: say if you have a headlamp that is mounted higher, 595 00:30:22,520 --> 00:30:27,000 Speaker 8: it must be aimed lower. Whereas in the American regulation, 596 00:30:27,520 --> 00:30:31,200 Speaker 8: the maximum mounting height is higher, which automakers like because 597 00:30:31,240 --> 00:30:36,520 Speaker 8: you know, big tough trucks and SUVs, and any given 598 00:30:36,560 --> 00:30:39,840 Speaker 8: headlamp gets aimed the same, whether it's way up high 599 00:30:39,920 --> 00:30:43,680 Speaker 8: on a forward exclusion or way down low on uh, 600 00:30:44,240 --> 00:30:45,560 Speaker 8: you know, on a corvette. 601 00:30:45,640 --> 00:30:51,240 Speaker 1: Number two, So inspections in Europe they have headlight aim 602 00:30:51,360 --> 00:30:53,920 Speaker 1: as part of that process, you know we talked about 603 00:30:53,920 --> 00:30:54,920 Speaker 1: in the US, we don't do that. 604 00:30:55,440 --> 00:31:00,800 Speaker 8: They have periodic vehicle inspections that include headlamp aim and adjustment. 605 00:31:01,440 --> 00:31:05,320 Speaker 8: The cars with high output headlamps have leveling systems to 606 00:31:05,360 --> 00:31:09,120 Speaker 8: compensate at least for vehicle loading, and the fancier systems 607 00:31:09,160 --> 00:31:11,719 Speaker 8: compensate for irregularities in the road. 608 00:31:11,880 --> 00:31:17,000 Speaker 1: And in number three, they have this magical system called ADB. 609 00:31:17,800 --> 00:31:19,640 Speaker 5: ADB a dB. 610 00:31:21,320 --> 00:31:22,640 Speaker 3: What is ADB, you. 611 00:31:22,560 --> 00:31:26,520 Speaker 4: May be asking, Am I am actually a dirty bastard? 612 00:31:26,840 --> 00:31:27,800 Speaker 5: Yeah. 613 00:31:28,120 --> 00:31:33,240 Speaker 8: ADB Adaptive driving Beam has been around for it's getting 614 00:31:33,320 --> 00:31:37,920 Speaker 8: on for two decades now in Europe. A good ADB 615 00:31:38,120 --> 00:31:42,280 Speaker 8: system can give the driver thirty meters about one hundred 616 00:31:42,360 --> 00:31:46,440 Speaker 8: feet greater seeing distance without more glare than a low beam, 617 00:31:46,680 --> 00:31:50,160 Speaker 8: which is a huge accomplishment. I mean, that's you know, 618 00:31:50,360 --> 00:31:54,480 Speaker 8: the problem has always been that low beams don't give 619 00:31:54,560 --> 00:31:57,760 Speaker 8: long enough seeing distance for the speeds that people actually drive, 620 00:31:57,800 --> 00:31:59,920 Speaker 8: so we overdrive our low beams and we hit things, 621 00:32:00,840 --> 00:32:03,000 Speaker 8: while high beams produce way too much clear for use 622 00:32:03,040 --> 00:32:09,160 Speaker 8: in traffic, and so ADB adaptive driving beam meekly resolves 623 00:32:09,160 --> 00:32:10,600 Speaker 8: that problem to a great degree. 624 00:32:10,600 --> 00:32:11,320 Speaker 6: And for those who. 625 00:32:11,280 --> 00:32:14,160 Speaker 8: Don't know what ADB does is it takes that high 626 00:32:14,200 --> 00:32:19,240 Speaker 8: beam pattern and it puts dark spots and slices in it, 627 00:32:19,640 --> 00:32:23,360 Speaker 8: following the locations of other road users' eyes. 628 00:32:23,920 --> 00:32:26,760 Speaker 1: Gotcha, Okay, so there's a if there's an oncoming car, 629 00:32:27,640 --> 00:32:30,320 Speaker 1: it'll try to limit the amount of light that's going 630 00:32:30,640 --> 00:32:32,440 Speaker 1: into that oncoming drivers. 631 00:32:32,520 --> 00:32:33,680 Speaker 6: Hot, that's exactly right. 632 00:32:36,000 --> 00:32:40,959 Speaker 4: Listen to the lengths that Europeans go through to just 633 00:32:41,000 --> 00:32:44,640 Speaker 4: like have like basic care about each other. It's so crazy. 634 00:32:44,720 --> 00:32:46,320 Speaker 1: This kind of blew my mind when I found out 635 00:32:46,360 --> 00:32:49,760 Speaker 1: this was a thing that existed, especially because we talked 636 00:32:49,800 --> 00:32:52,520 Speaker 1: so much about clear Obviously, he said there's some limitations 637 00:32:52,560 --> 00:32:54,480 Speaker 1: to it. Yeah, if you get in a city and 638 00:32:54,520 --> 00:32:56,800 Speaker 1: there's just cars everywhere, Yeah, there's only so much it 639 00:32:56,840 --> 00:32:58,560 Speaker 1: can do, and there's you know, then it. 640 00:32:58,560 --> 00:32:59,920 Speaker 3: Just results back to the lot. 641 00:33:00,440 --> 00:33:02,480 Speaker 1: But I was like, oh, this is really interesting because 642 00:33:02,480 --> 00:33:05,360 Speaker 1: it's a combination, but it also reduces glare. It seems 643 00:33:05,400 --> 00:33:08,640 Speaker 1: like best case scenario, right, It's like you get as 644 00:33:08,680 --> 00:33:12,600 Speaker 1: much visibility as possible, but you're also not obstructing other 645 00:33:12,640 --> 00:33:13,280 Speaker 1: people driving. 646 00:33:13,640 --> 00:33:15,320 Speaker 3: It used to be. 647 00:33:16,680 --> 00:33:20,280 Speaker 1: Just in high end cars, but now it's in you know, 648 00:33:20,440 --> 00:33:23,760 Speaker 1: like the version of a camera essentially, so it's in 649 00:33:24,640 --> 00:33:29,200 Speaker 1: all all the cars. We do not have this technology 650 00:33:29,280 --> 00:33:30,200 Speaker 1: in the US, So. 651 00:33:30,680 --> 00:33:34,560 Speaker 7: This isn't it's not like a regulation, is it, Like, 652 00:33:34,640 --> 00:33:35,640 Speaker 7: do they need to have it? 653 00:33:35,640 --> 00:33:36,160 Speaker 3: It's optional. 654 00:33:36,440 --> 00:33:39,800 Speaker 7: Yeah, But because it's so, but it's common, yeah, yeah, 655 00:33:39,840 --> 00:33:40,600 Speaker 7: I mean why not. 656 00:33:40,960 --> 00:33:45,560 Speaker 4: So if you're, for example, Toyota and you're making the 657 00:33:45,600 --> 00:33:48,680 Speaker 4: same fucking car, but one of them is going to 658 00:33:48,920 --> 00:33:52,040 Speaker 4: Europe and ones going to the US, they're like actively 659 00:33:52,280 --> 00:33:54,720 Speaker 4: keeping ADB in the European one and not in the 660 00:33:54,960 --> 00:33:55,800 Speaker 4: American one. 661 00:33:56,360 --> 00:33:59,360 Speaker 1: So I looked into it, and this is true. We 662 00:33:59,440 --> 00:34:02,400 Speaker 1: have cars in the US that have ADB functionality, but 663 00:34:02,560 --> 00:34:05,800 Speaker 1: it's been disabled. As people have been complaining about glare, 664 00:34:06,040 --> 00:34:09,840 Speaker 1: there's been a growing movement in the US to get ADB. 665 00:34:10,040 --> 00:34:13,319 Speaker 5: ADB movement in or version of ADB in the US. 666 00:34:14,239 --> 00:34:18,359 Speaker 8: The US devises and promulgates its own regulations, which are 667 00:34:18,400 --> 00:34:22,280 Speaker 8: in many cases quite different to the rest of world regulation. 668 00:34:22,640 --> 00:34:26,040 Speaker 8: When it looked like ADB was going to gain traction 669 00:34:26,120 --> 00:34:29,200 Speaker 8: and be a thing, NITSA went to the Society of 670 00:34:29,239 --> 00:34:30,360 Speaker 8: Automotive Engineers. 671 00:34:30,600 --> 00:34:34,279 Speaker 1: So the National Highway Traffic Safety Administration otherwise known as 672 00:34:34,400 --> 00:34:38,080 Speaker 1: NITSA told this group, hey, translate to European ADB for 673 00:34:38,280 --> 00:34:40,960 Speaker 1: US regulations. And the group was able to do it 674 00:34:41,080 --> 00:34:42,240 Speaker 1: in record time. 675 00:34:42,080 --> 00:34:46,120 Speaker 8: And NITSA said, yeah, thanks, but psych we're not going 676 00:34:46,160 --> 00:34:50,520 Speaker 8: to use that. And then things got really interesting. 677 00:34:50,719 --> 00:34:53,640 Speaker 1: So here's what we get to President Biden in his 678 00:34:53,760 --> 00:34:59,000 Speaker 1: infrastructure bail, which eventually became an infrastructural law, Congress tilled NITZA, Hey, 679 00:34:59,200 --> 00:35:02,040 Speaker 1: actually you need to adapt this ADB system that that 680 00:35:02,080 --> 00:35:07,080 Speaker 1: group put together. Is this actually Joe Biden's legacy instead 681 00:35:07,120 --> 00:35:09,680 Speaker 1: of the stubborn old man who refused to drop out 682 00:35:09,719 --> 00:35:11,720 Speaker 1: when it was clear that he shouldn't be running anymore, 683 00:35:11,880 --> 00:35:15,960 Speaker 1: can he be the president who saves us from headline 684 00:35:16,040 --> 00:35:21,560 Speaker 1: Blair turns out Now NITA said they're not going to 685 00:35:21,680 --> 00:35:22,400 Speaker 1: use that system. 686 00:35:22,560 --> 00:35:26,680 Speaker 8: We're instead we are going to devise our own standard. 687 00:35:26,920 --> 00:35:29,319 Speaker 1: And they are saying we're not going to do it 688 00:35:29,400 --> 00:35:33,200 Speaker 1: because actually we have a version that is more stringent 689 00:35:33,640 --> 00:35:38,000 Speaker 1: than the version that you guys found off on. So 690 00:35:38,120 --> 00:35:40,120 Speaker 1: I was like, Okay, more stringent, So yeah, maybe it's 691 00:35:40,160 --> 00:35:42,440 Speaker 1: even better. Sure, you know, we do a lot of 692 00:35:42,440 --> 00:35:45,120 Speaker 1: things better over here exactly, so maybe we're going to 693 00:35:45,200 --> 00:35:46,000 Speaker 1: have a better version. 694 00:35:46,920 --> 00:35:52,560 Speaker 8: It exerts requirements that don't exist in terms of system design, construction, 695 00:35:52,840 --> 00:35:57,360 Speaker 8: and testing it in the rest of the world regulation, 696 00:35:57,840 --> 00:36:01,120 Speaker 8: and so it makes for a more expensive of less 697 00:36:01,200 --> 00:36:02,520 Speaker 8: performance system. 698 00:36:02,800 --> 00:36:05,880 Speaker 1: So you're saying that they're thinking that their system is 699 00:36:05,960 --> 00:36:10,000 Speaker 1: better because it is more restrictive, but you're saying that 700 00:36:10,040 --> 00:36:13,359 Speaker 1: what they're proposing is not going to reduce GLAR more 701 00:36:13,400 --> 00:36:14,480 Speaker 1: than the Euro version. 702 00:36:14,360 --> 00:36:15,319 Speaker 6: It's actually going to do. 703 00:36:15,680 --> 00:36:20,040 Speaker 8: It can't because the sort of a key difference is 704 00:36:20,080 --> 00:36:23,120 Speaker 8: that the rest of world system says that the shadows 705 00:36:24,120 --> 00:36:27,160 Speaker 8: for other drivers on the road that the system creates 706 00:36:27,719 --> 00:36:29,760 Speaker 8: shall be as dark as possible. 707 00:36:31,120 --> 00:36:33,120 Speaker 6: The US specification says you. 708 00:36:33,080 --> 00:36:37,200 Speaker 8: May not make that shadow any less intense then a 709 00:36:37,320 --> 00:36:40,120 Speaker 8: regular static lo being would be at that same point 710 00:36:40,160 --> 00:36:44,960 Speaker 8: in the beam. So if the other driver or the 711 00:36:45,040 --> 00:36:48,560 Speaker 8: other road user happens to be in front of your 712 00:36:48,600 --> 00:36:51,600 Speaker 8: car in a location where a regular lo being would 713 00:36:51,600 --> 00:36:55,720 Speaker 8: be very intense, well there's still going to be very intense. 714 00:36:55,880 --> 00:36:57,480 Speaker 8: It will be less intense than it would be from 715 00:36:57,480 --> 00:36:59,479 Speaker 8: a high beam, but it'll still be very intense because 716 00:36:59,480 --> 00:37:01,200 Speaker 8: it's as though it's a full intensity. 717 00:37:01,239 --> 00:37:07,880 Speaker 1: LOWBOO is the baseline in the US version of what 718 00:37:07,920 --> 00:37:11,600 Speaker 1: they're proposing here, that's right. I can't do anything less 719 00:37:11,600 --> 00:37:14,680 Speaker 1: than that, whereas in the europe system, like you said, 720 00:37:14,680 --> 00:37:17,400 Speaker 1: you can get as close to as dark as possible. 721 00:37:18,480 --> 00:37:18,960 Speaker 6: That's right. 722 00:37:20,840 --> 00:37:24,480 Speaker 8: Maybe NITSA looked at everything and had a good reason 723 00:37:24,520 --> 00:37:29,120 Speaker 8: for deciding that the US needs a different ADB system 724 00:37:29,440 --> 00:37:32,040 Speaker 8: that that does not reduce glare as much and is 725 00:37:32,080 --> 00:37:33,239 Speaker 8: more expensive to make. 726 00:37:34,280 --> 00:37:36,600 Speaker 1: I reached out to NISA for comment, but they didn't 727 00:37:36,640 --> 00:37:39,360 Speaker 1: respond because it's going to be more expensive and it 728 00:37:39,400 --> 00:37:43,200 Speaker 1: seems like not as effective. It doesn't seem like automakers 729 00:37:43,239 --> 00:37:47,080 Speaker 1: are going to voluntarily adapt the system in the US 730 00:37:47,120 --> 00:37:47,759 Speaker 1: anytime soon. 731 00:37:48,760 --> 00:37:50,040 Speaker 6: Well, I think I think we will see it. 732 00:37:50,080 --> 00:37:52,319 Speaker 8: I mean, and the first US system is on the road. 733 00:37:52,360 --> 00:37:56,520 Speaker 6: The Rivian has it, Okay, I don't know anything. 734 00:37:56,200 --> 00:37:59,400 Speaker 8: About the the how how good the performance might be 735 00:37:59,440 --> 00:38:03,320 Speaker 8: of that system by having driven it, so I definitely 736 00:38:03,360 --> 00:38:07,280 Speaker 8: think it will be offered on premium, high end vehicles 737 00:38:07,560 --> 00:38:10,440 Speaker 8: at a high cost. I don't think it's going to 738 00:38:10,480 --> 00:38:13,600 Speaker 8: filter down to the popular priced vehicles. 739 00:38:13,960 --> 00:38:16,719 Speaker 1: Yeah, no one is. He doesn't have much hope for it. 740 00:38:17,719 --> 00:38:29,319 Speaker 1: But there's another curve ball, what's what next run. Even 741 00:38:29,360 --> 00:38:34,600 Speaker 1: in places like Europe that have ADB and you know, 742 00:38:35,320 --> 00:38:36,920 Speaker 1: think about glare a lot more than we do in 743 00:38:36,920 --> 00:38:40,279 Speaker 1: the US, glare complaints are still going up. 744 00:38:41,320 --> 00:38:43,319 Speaker 5: Wow, this is a gut punch. 745 00:38:43,600 --> 00:38:44,120 Speaker 2: This is. 746 00:38:45,560 --> 00:38:49,879 Speaker 4: This is hard to hear. So they've got all these precautions, 747 00:38:49,960 --> 00:38:54,480 Speaker 4: all these regulations and all these stipulations are still and 748 00:38:54,560 --> 00:38:55,920 Speaker 4: people still feel like we feel. 749 00:38:56,080 --> 00:38:58,879 Speaker 8: The fact that glare complaints, headlight glare complaints are up 750 00:38:58,960 --> 00:39:02,879 Speaker 8: all over the world, even in countries with stringent glare 751 00:39:02,960 --> 00:39:06,960 Speaker 8: controls and leaving ADB aside for the moment, because it's 752 00:39:07,000 --> 00:39:09,880 Speaker 8: it's still most cars still just have low even HIGHBI 753 00:39:10,120 --> 00:39:13,960 Speaker 8: all over the world. The fact that the glare complaints 754 00:39:14,000 --> 00:39:17,319 Speaker 8: are increasing, both here in North America where we don't 755 00:39:17,320 --> 00:39:20,880 Speaker 8: care about controlling glare, and in Europe and Australia and 756 00:39:20,960 --> 00:39:23,920 Speaker 8: Japan and all these other countries where they do, that 757 00:39:24,080 --> 00:39:27,480 Speaker 8: tells me that it's probably down to aspects that are 758 00:39:27,520 --> 00:39:31,400 Speaker 8: not regulated anywhere in the world, which is luminance driven 759 00:39:31,440 --> 00:39:34,640 Speaker 8: by headlight size and color, which say the bluer. 760 00:39:35,160 --> 00:39:37,000 Speaker 1: So if you had the wave of magic wand that 761 00:39:37,040 --> 00:39:39,439 Speaker 1: it is its first two things you're addressing. You're you're 762 00:39:39,560 --> 00:39:43,000 Speaker 1: changing the color of the headlands, and you're you're making 763 00:39:43,000 --> 00:39:44,000 Speaker 1: a rule about luminance. 764 00:39:44,960 --> 00:39:47,719 Speaker 8: Ooh, that's a tough question. I often think about it 765 00:39:47,760 --> 00:39:50,280 Speaker 8: in those very terms. What you know, how many wishes 766 00:39:50,320 --> 00:39:52,560 Speaker 8: do I get with this magic wand before it burns out? 767 00:39:53,960 --> 00:39:57,320 Speaker 8: I think it's it's a really tough call. 768 00:39:57,160 --> 00:39:58,279 Speaker 6: If I only get one. 769 00:39:59,480 --> 00:40:03,040 Speaker 8: But if if I only get one, then it really 770 00:40:03,120 --> 00:40:06,720 Speaker 8: has to be. I wave the magic wand and poof 771 00:40:06,920 --> 00:40:10,799 Speaker 8: all cars headlamps are aimed correctly and kept that way 772 00:40:10,920 --> 00:40:11,440 Speaker 8: no matter what. 773 00:40:11,760 --> 00:40:14,440 Speaker 6: Okay, Now if you start to tell me I have two. 774 00:40:14,320 --> 00:40:16,399 Speaker 1: Or three, you'll give you three. 775 00:40:16,440 --> 00:40:17,480 Speaker 6: Okay, great, all right? 776 00:40:17,560 --> 00:40:19,480 Speaker 8: So that was that was That was my first one 777 00:40:19,480 --> 00:40:21,560 Speaker 8: that you know, I waved the magic wand once poof 778 00:40:21,640 --> 00:40:24,319 Speaker 8: all vehicles have their headlamps aimed correctly and they stay 779 00:40:24,360 --> 00:40:25,000 Speaker 8: that way. 780 00:40:25,080 --> 00:40:28,120 Speaker 6: No matter what. Ye two and three. 781 00:40:28,640 --> 00:40:32,560 Speaker 8: Yeah, they're probably going to be a limit on luminants, 782 00:40:32,560 --> 00:40:35,279 Speaker 8: which is going to mean headlamps have to get bigger again. 783 00:40:35,360 --> 00:40:37,359 Speaker 8: They can no longer be this you know, tiny little 784 00:40:37,360 --> 00:40:40,000 Speaker 8: strip of light or tiny little you know, three dots 785 00:40:40,000 --> 00:40:45,279 Speaker 8: of light and uh, sort of roll back this this 786 00:40:45,480 --> 00:40:47,359 Speaker 8: incessant trend towards bluer. 787 00:40:47,120 --> 00:40:49,440 Speaker 6: Light, get a get a warmer white light color. 788 00:40:50,040 --> 00:40:51,920 Speaker 1: So I asked him where do we go from here? 789 00:40:51,960 --> 00:40:52,640 Speaker 3: We just screwed. 790 00:40:54,040 --> 00:40:57,840 Speaker 1: He compared it to kind of like pollution and the 791 00:40:57,880 --> 00:41:00,120 Speaker 1: evolution that I had right, Like, pollution was bad for 792 00:41:00,160 --> 00:41:02,239 Speaker 1: a while and then eventually people are like this kind 793 00:41:02,239 --> 00:41:02,560 Speaker 1: of sucks. 794 00:41:02,600 --> 00:41:03,520 Speaker 3: We don't want to live this way. 795 00:41:03,719 --> 00:41:05,960 Speaker 1: Yeah, and it was enough of a ground spell and 796 00:41:06,000 --> 00:41:10,799 Speaker 1: then things started to change. But he's like, you got 797 00:41:10,800 --> 00:41:13,560 Speaker 1: to be careful with this stuff because it's not a 798 00:41:13,680 --> 00:41:16,920 Speaker 1: simple solution. And a lot of people think glare is 799 00:41:16,960 --> 00:41:19,239 Speaker 1: so easy to solve, just do X, but it's not 800 00:41:19,400 --> 00:41:23,960 Speaker 1: science backed. He says, science is slow and incremental. You're 801 00:41:24,000 --> 00:41:26,359 Speaker 1: not going to have change overnight, right, so, and you 802 00:41:26,400 --> 00:41:28,240 Speaker 1: need to make sure to change that you were asking 803 00:41:28,280 --> 00:41:31,680 Speaker 1: for actually backed by science, not motion based. 804 00:41:31,800 --> 00:41:35,480 Speaker 8: And yes, glare is infuriating. It's infuriating. You can't get 805 00:41:35,480 --> 00:41:37,000 Speaker 8: in the car and go to the grocery store for 806 00:41:37,000 --> 00:41:40,200 Speaker 8: a carton of ice cream without getting assaulted by headlight. 807 00:41:40,280 --> 00:41:41,920 Speaker 6: Claire, that is infuriating. 808 00:41:42,120 --> 00:41:45,279 Speaker 8: And it you know, you spend time on Facebook or 809 00:41:45,280 --> 00:41:47,680 Speaker 8: Reddit or wherever, and you want to vent and you 810 00:41:47,719 --> 00:41:50,360 Speaker 8: want a rant, and it's easy to get on side 811 00:41:51,200 --> 00:41:54,719 Speaker 8: with these charlatans, and they wind up sort of using 812 00:41:54,800 --> 00:41:56,840 Speaker 8: up all the oxygen in the room and polluting the 813 00:41:56,840 --> 00:41:59,719 Speaker 8: discussion space. I want to make it really clear that 814 00:42:00,040 --> 00:42:03,799 Speaker 8: light clear is real. Yeah, it is a problem. It 815 00:42:03,880 --> 00:42:07,160 Speaker 8: is a very complex problem because about all these moving 816 00:42:07,200 --> 00:42:10,080 Speaker 8: parts and real lives are at stake no matter which 817 00:42:10,120 --> 00:42:10,759 Speaker 8: way you go. 818 00:42:12,480 --> 00:42:13,720 Speaker 6: But I am. 819 00:42:13,640 --> 00:42:18,200 Speaker 8: Optimistic because I see political will developing. I see groups 820 00:42:18,239 --> 00:42:22,320 Speaker 8: of respectable scientists really thinking about the problem in ways 821 00:42:22,360 --> 00:42:26,840 Speaker 8: that they haven't before. And so I mean, leaving aside 822 00:42:27,640 --> 00:42:30,200 Speaker 8: the fact that we're at the start of at least 823 00:42:30,200 --> 00:42:35,040 Speaker 8: a four year period where regulators and regulatory agencies are 824 00:42:35,280 --> 00:42:38,960 Speaker 8: are on the chopping block and scientists are likely to 825 00:42:39,000 --> 00:42:41,960 Speaker 8: be muzzled, leaving that aside for the moment, if we 826 00:42:42,000 --> 00:42:45,600 Speaker 8: can sort of carve out that luxury, I am optimistic. 827 00:42:47,960 --> 00:42:48,160 Speaker 3: Yeah. 828 00:42:48,280 --> 00:42:51,680 Speaker 7: I mean it's interesting just kind of honing in on 829 00:42:51,760 --> 00:42:55,680 Speaker 7: the why don't we just make them yellow lights instead? 830 00:42:55,840 --> 00:42:58,080 Speaker 7: Like I do wonder if that's just a kind of 831 00:42:58,080 --> 00:43:00,840 Speaker 7: a taste thing that could seems like the most realistic 832 00:43:00,880 --> 00:43:04,200 Speaker 7: thing to actually change like based on just habits or 833 00:43:04,239 --> 00:43:06,680 Speaker 7: taste where people might think it's cool and retro even 834 00:43:07,320 --> 00:43:12,719 Speaker 7: to have like that more natural light thing. So maybe 835 00:43:12,960 --> 00:43:17,120 Speaker 7: just out of that more than the safety glare issue. 836 00:43:17,120 --> 00:43:19,880 Speaker 1: Well, they're shooting the new fast and fears now right, 837 00:43:20,640 --> 00:43:23,439 Speaker 1: call it then, Diesel.
