It was going 3mph over the speed limit, a perfectly reasonable speed that is still probably lower than almost everyone else on the road.

Serious question: how are speed limits enforced (or not) in the USA? From what I read on the internet, it seems like they are 90% unenforced, 10% arbitrarily enforced by cops who choose who they want to pull over from the masses who are routinely speeding. If they are mostly unenforced, how does the system work? Does everyone implicitly add 20% to the posted limit, or do they just go whatever speed feels right to the…

rich or connected -> warning

white -> warning or ticket

black -> ticket or execution

Well, if you saw that video and it really did show a So whether or not the police understand self-driving systems is not relevant to the fundamental physics problem. The key question is how long was the ped visible.

"ped"?

> That's a pretty clear fail. And yet the police were so quick to say that camera footage indicates that Uber was likely not at fault. It was so quick that it makes me inclined to think it's pretty obvious. However, after the SF Chronicle published its exclusive interview with the Tempe's chief of police, the Tempe Police PR person had to issue a statement that, "Tempe Police Department does not determine fault in ve…

If it falls to a question of stopping distances, self driving vehicles are not really practically different from any other car, save perhaps for the ability to reduce the reaction time phase of stopping. I can certainly imagine there will be scenarios in which experienced traffic cops can make a reasonable determination, especially if the speed, distances, locations etc of the car and pedestrian are known.

Yes, sorry for being unclear. I'm English, so I tend towards the mealy-mouthed. What I'm trying to say is that sushisource is being a cunt for dehumanizing the person that was killed.

According to the UK DOT the estimated pedestrian accident survival rate is 55% at 30mph and just 5% at 40mph (due to kinetic energy rather than reaction times) so 3mph in this range is not exactly an insignificant difference. The strangest thing about watching this story is that people who are apparently ignorant of this still feel sufficiently certain of the relative unimportance of speed differences in this range t…

> According to the UK DOT the estimated pedestrian accident survival rate is 55% at 30mph and just 5% at 40mph (due to kinetic energy rather than reaction times) so 3mph in this range is not exactly an insignificant difference. You'd have that range whether people went at the speed limit, above the speed limit, or below the speed limit. As long as speed limits are made with actual speeds taken into account (they are)…

The police spokesperson is quoted saying the vehicle was doing 38 in a 35mph zone, which is pretty much where the curve suggests an extra little bit of speed is most lethal. (Other reports have suggested other speed limits)

The NYT just published a graphic that purports to show the location of the vehicle and the victim: https://www.nytimes.com/interactive/2018/03/20/us/self-drivi... This is the first report I've seen that indicates the Uber AV was in the right lane. Remember that the victim was crossing from left to right, and that all of the visible damage on the AV is on the right-side bumper. It's very hard to imagine a scenario in…

If this was indeed the overall scenario, there are few factors I could think of that would excuse a human driver here: 1. Another car was in the lane left of the fatal car, blocking its view of the pedestrian. 2. The pedestrian fell back after reaching the curb. But it looks like both the artificial and the human driver were asleep.

1. Wouldn't the pedestrian have to walk through said car then? 2. Quite plausible, especially trying to heft what looks like a pretty heavy loaded bike onto a curb.

Which you follow up with a vulgarity? Come on. Be better than that. If your goal is to improve online discourse, lead by example.

”If the woman suddenly walked in front of the car at the last minute, I don't see how the situation could have been avoided” Likely, but not necessarily. Depending (hugely!) on what actually happened, it might be that the car should have started slowing down before the woman changed course. As an extreme example, if you’re driving at 50 mph and come up behind a kid cycling at the side of the road with a foot separati…

There definitely exists a sort of pre-cognitive human quality to traffic. Sometimes you just slow down on a subconscious hunch without any information on that particular situation. Or you might be very conscious not to slow down if you're driving a motorcycle in Asia in heavy traffic trying to make a turn with a huge truck barreling behind you. There are massive differences in road cultures between countries, and it…

That’s just human intuition, which is trained over time through experience. Which is also how machine learning works, so it’s not quite clear that humans have a sustainable advantage here.

by the right side of the vehicle doesn't seem likely.
