This is an example of the strong tendency to blame pedestrians for most to all pedestrian-vehicle collisions. In reality, pedestrians are generally at the bottom of the list for blame, behind even the engineers who designed the roads in the first place. In this situation, there is no evidence that the pedestrian did anything dangerous. She was crossing in what amounts to an unmarked crosswalk. When struck, she was we…

> If you object to the idea that it's an unmarked crosswalk I do. I've never seen another crosswalk with a "no pedestrians" sign.

That's one point of view, if you're a goodie two shoes who automatically follows and agrees with every law and rule you ever heard of, even if it violates your own basic ethical values.

Another point of view is that the state of arizona intentionally hates pedestrians and gratuitously creates roads that put their lives at risk when all they're trying to do is get home from the grocery store or whatever, a perfectly reasonable thing we oughtta all have the right to do without having to walk an extra mile out of our way or whatever.

In NYC, which is actually a reasonable jurisdiction in the USA, that dumb fuck Giuliani tried to enforce anti jay walking laws one time in the '90s. You know what happened? NYPD cops went on the record telling the NY Times they planned to intentionally leave their ticket books in their precinct lockers so they had no way of writing such idiotic tickets. Police nullification, you could call it. Guliani immediately backed down and no one in recent memory has tried to do that again in downstate NYS.

> “Improving public safety has always been the emphasis of Arizona’s approach to autonomous vehicle testing, and my expectation is that public safety is also the top priority for all who operate this technology in the state of Arizona,” Mr. Ducey said in his letter. “The incident that took place on March 18 is an unquestionable failure to comply with this expectation.” This after the police claimed no fault.[1] Not q…

The investigation isn't complete, but Uber did disable the car's own safety features [0].

Both Volvo and Intel tested their software against the low-grade video that was released, and it was able to detect the impending accident and reduce the impact to where the pedestrian would likely have survived.

I'd be very interested in seeing the math if you have the time later.

95% - erring on assuming Uber has driven more miles than they probably have. https://news.ycombinator.com/item?id=16621118

Hmm; if I understand correctly, in that link you show that if Uber’s AI has the same risk of killing people as a human driver, then the prior probability of an accident occurring when it did or earlier was 5%. That’s significant, but it’s not the same measure as the probability that the AI has a higher risk (which would require a prior distribution).

> bad actions of a few What bad actions? If you mean an AI car killing a person - that's hardly "an action", that's an accident. Classic human-driven cars kill people every day yet are allowed to continue operation. Do people really expect self-driving cars to be not just more safe than classic but actually 100% safe? By the way I myself don't drive at all and only use public transport (and a bicycle to ride the coun…

>What bad actions? Uber disabled the safety systems included with the car that was involved in the incident. They relied solely on their own, half-baked tech when these systems could have saved the life of person who was killed: https://www.bloomberg.com/news/articles/2018-03-26/uber-disa...

I remain interested in why the lidar didn't work in this case and I hope more details emerge so we can learn what happened.

But it seems logical that Uber would disable the onboard built-in volvo crash detection feature, it would be adding another variable for a car that is intended to test one thing at a time. Its hard to see this solely as the "uber is being reckless" narrative instead of "maybe this is just how all self-driving cars are tested".

I am happy to be proven wrong certainly

For all of the theoretical moral questions that have been brought up around self driving cars (the proverbial lever that lets you kill one person instead of a handful, for example), it's interesting/inevitable that this one came up first. I'm sure lots of people will argue that self-driving cars will, in the long run, save a lot of lives, and therefore we can justify some loss of life in the process. They are probabl…

I'm going to take your post apart because I enjoyed it very much...

> For all of the theoretical moral questions that have been brought up around self driving cars (the proverbial lever that lets you kill one person instead of a handful, for example), it's interesting/inevitable that this one came up first.

Your talking about the "trolley problem" and it is a ethical question as opposed to moral. This is literally a fuckup, bad programing or poor design. We are going to have real ethical concerns because at some point a car is going to have to make a choice pedestrian or occupant - and I know that my elderly father would choose himself if he were in the car, but I might make a different choice.... will the cars ethics ever reflect my own?

> I'm sure lots of people will argue that self-driving cars will, in the long run, save a lot of lives, and therefore we can justify some loss of life in the process. They are probably right about self-driving cars saving more lives in the long run, but I don't know that the conclusion follows.

It is a tough one, and if there is more loss of life does using a self driving car a bit of fruit off a poison tree.

https://en.wikipedia.org/wiki/Eduard_Pernkopf springs to mind when you bring this up.

> From what has been released so far, this feels like a case where a human would have had a high likelihood of doing the same thing

Except the fact that when you look at footage of the road when driven on with a decent camera recording rather than the crapy low quality and very much artificially dark uber footage this looks to have been very avoidable. If the guy who was supposed to be there to take over had been looking up right then, we might not be talking about this at all...

> As someone with a little bit of experience with the machine learning side of things, I understand how this stuff is really hard, and I can imagine a handful of ways the system could have been confused, which makes it all the more important to understand what went wrong and how we could prevent it from happening in the future.

Were talking about uber here... it is also just as likely that they are in way over their heads.

> As self-driving cars become more prevalent, things like this will happen and it will be tough to walk the line between over-reacting to every incident and killing progress in this area and designing safe cars that don't make the problem worse.

When I read this bit I felt compelled to respond - the life of one victim is too many. In the early days of aviation people knew the risks... But this wasn't the test pilot who died this was a woman walking down the road. I look forward to the NTSB report - they tend to be the adults in these situations.

> From what has been released so far, this feels like a case where a human would have had a high likelihood of doing the same thing and would not have been at-fault in the collision. But self-driving cars have more sensors and, in theory, more capabilities to prevent something like this, and we absolutely should expect them to do better.

Intel and Volvo tested against the terrible dashcam footage. If Uber hadn't disabled the XC90's safety systems, this wouldn't have happened. [0]

The systems today can do better.

How is this company still in business...karma is chasing it all the way down to oblivion!

Outside of Hacker News, I have never encountered anyone who followed, was fully aware of, or cared about Uber scandals. From my conversations, it seems that people in my city hate taxi companies so much that it takes more than a couple of manslaughters to make them stop using Uber.

Unlike Uber, Waymo has always said they do not believe (based on data and experience) "safety drivers" are a realistic safety measure, because normal human beings do not have the ability to concentrate hard on a task for 8 hours a day that they have absolutely no control/feedback upon. If this is not obvious to you, you have never tried doing such a task. Try it and you will change your mind immediately.

I believe the safety drivers are primarily responsible for getting the autonomous cars to resume driving again after they've stopped for some unknown reason, not to react in a fraction of a second to divert a disaster.

In practice, yes.

In theory, as is obvious from all these comment threads, people seem to think the "safety drivers" (think about that name...) are there to actually, like, you know, improve safety.

As a pedestrian, it's still our responsibility to make sure approaching vehicles are actually stopped before we start crossing. She did not, or she would be alive.

It's certainly prudent to do so, and any amount of self-preservation says you should, but is not checking if you're about to be run over actually negligent ? Edit: Also, if you as a pedestrian, stand at a 35mph road, at night, and wait for all approaching cars to stop before you start crossing, you will be standing there a very long time indeed.

I don't know much about the logic used in self-driving cars - but I do wonder how they will handle roundabouts. We have a lot of them here (Australia) and you have to give way to a car that is approaching or entering the roundabout on your right - which often is opposite you. How will a self-driving car cope with detecting a vehicle behind the concrete barrier of a roundabout?
