00:00:01,920 --> 00:00:06,440
Speaker 1: Welcome to brain Stuff production of I Heart Radio. Hey

2
00:00:06,519 --> 00:00:09,000
Speaker 1: brain Stuff. I'm Lauren vogel Bomb, and this is a

3
00:00:09,039 --> 00:00:12,840
Speaker 1: classic brain Stuff episode. This one originally aired a few

4
00:00:12,920 --> 00:00:16,479
Speaker 1: years back, and unfortunately, we're not very much closer to

5
00:00:16,560 --> 00:00:20,400
Speaker 1: having autonomous vehicles capable of driving us around. I say

6
00:00:20,480 --> 00:00:24,120
Speaker 1: unfortunately because it could be a lot safer than human

7
00:00:24,200 --> 00:00:27,479
Speaker 1: drivers managed to be, because they would follow the rules

8
00:00:27,480 --> 00:00:30,720
Speaker 1: of the road better, Which brings us to an interesting question.

9
00:00:31,400 --> 00:00:37,440
Speaker 1: Why can today's autonomous vehicles exceed the speed limit? Hey

10
00:00:37,520 --> 00:00:40,600
Speaker 1: brain Stuff, Lauren vogel Bomb. Here, imagine a future in

11
00:00:40,600 --> 00:00:43,360
Speaker 1: which you climb into the back of yourself driving autonomous

12
00:00:43,479 --> 00:00:45,920
Speaker 1: vehicle and instructed to take you on a late night

13
00:00:45,960 --> 00:00:50,200
Speaker 1: fast food run. Imagine also that you're particularly famished that night.

14
00:00:50,840 --> 00:00:53,199
Speaker 1: Would you be able to tell the computer to exceed

15
00:00:53,240 --> 00:00:55,120
Speaker 1: the posted speed limit and get you to your chicken

16
00:00:55,160 --> 00:00:57,800
Speaker 1: nuggets a little more quickly? Or will the system remind

17
00:00:57,800 --> 00:01:00,280
Speaker 1: you in a polite but firm, synthesized voice that you

18
00:01:00,360 --> 00:01:05,119
Speaker 1: have to That's a hard question to answer, since level

19
00:01:05,160 --> 00:01:08,280
Speaker 1: five autonomous vehicles, the hypothetical ones equipped to be able

20
00:01:08,319 --> 00:01:11,240
Speaker 1: to drive in any sort of environment with no human intervention,

21
00:01:11,480 --> 00:01:14,720
Speaker 1: are still somewhere away off in the future, but it

22
00:01:14,760 --> 00:01:17,559
Speaker 1: seems likely that when robotic cars hit the market, they'll

23
00:01:17,600 --> 00:01:20,600
Speaker 1: be designed to stick to speed limits, except perhaps when

24
00:01:20,600 --> 00:01:24,399
Speaker 1: safety requires speeding up. A few years back, when experimental

25
00:01:24,400 --> 00:01:28,280
Speaker 1: autonomous vehicles first began appearing on American roads, Reuters reported

26
00:01:28,280 --> 00:01:31,320
Speaker 1: that Google's self driving cars actually were designed to go

27
00:01:31,440 --> 00:01:34,399
Speaker 1: up to ten miles or sixteen kilometers faster than the

28
00:01:34,400 --> 00:01:37,960
Speaker 1: speed limit when traffic conditions made it necessary. The problem

29
00:01:38,040 --> 00:01:40,720
Speaker 1: wasn't that the robots got unpatient, but rather that human

30
00:01:40,800 --> 00:01:44,440
Speaker 1: drivers routinely exceed posted speed limits and tend to go

31
00:01:44,480 --> 00:01:46,399
Speaker 1: as fast as they think they can get away with

32
00:01:46,400 --> 00:01:49,320
Speaker 1: without getting a ticket. Researchers worried that with all those

33
00:01:49,400 --> 00:01:52,120
Speaker 1: humans out there careening around as fast as possible, it

34
00:01:52,200 --> 00:01:54,480
Speaker 1: might be dangerous for robots to plot along at the

35
00:01:54,560 --> 00:01:57,840
Speaker 1: legal limit or lower, but so far, there aren't any

36
00:01:57,880 --> 00:02:01,320
Speaker 1: signs that autonomous cars are prone to speeding. In California,

37
00:02:01,400 --> 00:02:04,600
Speaker 1: the only state that keeps track of accidents involving autonomous vehicles,

38
00:02:04,800 --> 00:02:08,600
Speaker 1: there have been nearly fifty mishaps reported since, and many

39
00:02:08,600 --> 00:02:11,079
Speaker 1: of them it was a human driven vehicle that rear

40
00:02:11,240 --> 00:02:14,680
Speaker 1: ended an autonomous one, often when the robot cautiously slowed

41
00:02:14,680 --> 00:02:18,040
Speaker 1: tield to another car or a pedestrian. In other instances,

42
00:02:18,120 --> 00:02:21,200
Speaker 1: human drivers got frustrated with slow poke autonomous vehicles and

43
00:02:21,240 --> 00:02:25,600
Speaker 1: clipped them as they tried to pass. According to report

44
00:02:25,680 --> 00:02:28,800
Speaker 1: on Speed Limits by the National Conference of State Legislatures,

45
00:02:29,000 --> 00:02:32,280
Speaker 1: government traffic planners envision a future in which autonomous vehicles

46
00:02:32,280 --> 00:02:35,239
Speaker 1: will most likely be programmed to not exceed the posted

47
00:02:35,280 --> 00:02:38,880
Speaker 1: speed limit in an area. Moreover, they're hoping that regimentation

48
00:02:39,000 --> 00:02:41,480
Speaker 1: will make the road safer because it will reduce the

49
00:02:41,560 --> 00:02:44,000
Speaker 1: danger that develops when the roads are filled with vehicles

50
00:02:44,040 --> 00:02:47,280
Speaker 1: traveling at varying rates of speed. On the downside, the

51
00:02:47,280 --> 00:02:50,400
Speaker 1: author's note, a proliferation of law abiding robots will mean

52
00:02:50,400 --> 00:02:52,800
Speaker 1: a reduction in the revenue that state and local governments

53
00:02:52,840 --> 00:02:56,400
Speaker 1: have been getting from ticketing speeders. But if we ever

54
00:02:56,440 --> 00:02:58,400
Speaker 1: get to the point where we have enough self driving

55
00:02:58,400 --> 00:03:00,240
Speaker 1: cars on the road that we could have row bought

56
00:03:00,240 --> 00:03:03,480
Speaker 1: only highway routes, networked vehicles might be able to travel

57
00:03:03,520 --> 00:03:07,000
Speaker 1: safely at higher speeds than human drivers. And University of

58
00:03:07,040 --> 00:03:10,280
Speaker 1: Illinois researchers say that because autonomous vehicles are designed to

59
00:03:10,320 --> 00:03:13,640
Speaker 1: adjust to and accommodate human drivers, maneuvers even a small

60
00:03:13,639 --> 00:03:16,080
Speaker 1: proportion of robots driving out a highway as few as

61
00:03:16,120 --> 00:03:18,880
Speaker 1: five percent of total cars could eliminate the stop and

62
00:03:18,919 --> 00:03:26,760
Speaker 1: go waves that lead to congestion. Today's episode was written
