It also seems strange that the rest of the tractor trailer was not picked up by the radar when it was entering the road in the first place - the front part that is pulling the trailer is typically lower and should not have been mistaken for a road sign or otherwise.

Re: A Tragic Loss
#322I mean I understand Tesla has to make a statement here and I understand they want to ensure everyone that it's not really their fault but to title a post "A Tragic Loss" and then spend the majority of the post discussing all of your car's safety features and how it wasn't your fault just seems tone deaf and distasteful to me. Maybe they had to do it for legal reasons I don't know (I'm certainly not a lawyer) and I'd…
If their detectors don't see a white car against a bright background, that's obviously a serious problem.

> Based on what? Human drivers are very bad. We kill over 32,000 people a year (and that's a 60 year low, just a few years ago it was over 40,000). So if self driving cars are just a little better than humans, they will save many lives. If they are a lot better than us, they will save many more.

This. Notice how quick they are to bring up "this is the first fatality in 130 million miles", but AFAICT, traffic fatalities in the US occur at a frequency of around 10 per billion miles [1], which is the same. So even though this is just one data point, it's spot on the current average for fatality frequency in normal cars. Furthermore, to gather enough statistics to be able to say with confidence "semi-autonomous…
The IIHS compares car model fatality rates: http://www.iihs.org/iihs/topics/driver-death-rates If you want to do the numbers to compare the Tesla to other cars, where they measure driver fatalities per million registered years, do this: 130,000,000 miles / 12,000 average miles per year per car = 10,833 years. That's 10,833 registered years for the Model S. The IIHS site normalizes to deaths per million registered yea…

The radar might not be able to clearly distinguish between objects at the height of the cab and objects at signage heights. Just about everything on the road is mostly on the road. If the system can bias its sampling towards the ground, it would make a lot of sense to do so. Lump "above the ground" and "very above the ground" into the same category and use other sensors (for example, the camera..) to detect the edge…
Of course we should have undercarriage bars regardless.
Re: A Tragic Loss
#326I am not sure what happened in this situation, but I have to warn any HNers that have teslas or might get behind the wheel of one -- do not rely on the autopilot!!! If you are using the autopilot you must be in a heightened sense of alert, not lowered. The autopilot can get you into a dicey situation, and then you have to take over control and react very fast.

"Acceptable losses" is, and has always been the rule when it comes to accidents in all cars , ever. We've made absolutely massive safety improvements in the last few decades, cutting the death rate to around 1/3 of its historical maximum, yet even so tens…

Have you considered that perhaps there is no argument to be countered? That your entire foundation of "humanizing" the situation is foolish and off base? Alternatively, you yourself blithely dismissed the fact that your "humanizing" easily works both ways, in fact more easily works the other way: many of us have had friends or loved ones killed by driver error, tiredness, drunkeness/distraction, or in simple accidents, deaths that would not have happened if a computer had been in control. I don't need any "what ifs" because one of my friends was killed by a drunk driver right near her school. Those millions who are going to die have friends and loved ones too you know. It is in fact a statistics game, and one of economic tradeoffs. That's human life, in fact life in general.
>no amount of statistics would convince me that the tradeoff was worth it
Which is why we do not leave societal decisions to you, but instead have a system that attempts (with varying success in some cases) to put significant distance between the moment-to-moment emotions of specific individuals and enactment of law governing all. You may not care about this imaginary tradeoff of your loved one vs thousands of other people's loved ones, but those other thousands of people certainly would. So you can and should be outvoted.
>Who bears responsibility in that case?
It would depend. If it was just an honest mistake that could not have been reasonably caught, then the answer is "no one" and it'd just be covered by insurance, or even the government, so you could say that "society itself chooses to take responsibility for the greater good". We already have a model for this in many, many other scenarios because the basic issue here is very much not a new one. A big, successful example would be vaccines, where we all have to take on a small risk for a very great general good and there is government provided compensation in the rare case that something goes wrong. However as far as individuals go, sometimes there is in fact no one "at fault" or responsible. It's human to always want something to blame but part of maturing is accepting that freak risk is a fact of existence.
>I suspect that ordinary people won't accept that for a long time to come.
We literally do accept it, and have accepted it for all of recorded history. Much of mythology comes out of the basic recognition that there are forces beyond humanity.
>At least with a human in the mix, we're all still operating within the same social and legal order.
Debatable, but also beside the point and it doesn't change the objective fact that a human in the mix is a proven recipe for failure. Your philosophy is cold comfort in the face of tens of millions of deaths. You are also ignoring the large percentage of deaths that are purely down to things such as animals crossing the road, or poor driving conditions that are not reacted to appropriately, or where a driver kills themselves (and perhaps passengers) due to human failure but involves no 3rd parties, which automation could also positively effect.
You're also ignoring positive utility, which is a critical component to the economic and societal equation just as the car itself is. Self-driving cars change the dynamics for city space usage, for people who are unable to drive due to age or medical conditions, for the poor who cannot afford the capital outlay of a full car, for those who are discriminated against by human drivers, for the environment (long charging times for electric vehicles become significantly less of an issue when the vehicles can simply go take care of it themselves while you're doing something else), and on and on. It's hard to overstate how central this is to society up and down the stack. Your viewing lens is entirely too narrow, which is precisely why individual emotional response is a terrible basis for governance.

And let's recall that this isn't a choice between "human drivers, no lives lost" vs. "AI drivers, some lives lost". It's a choice between "human drivers, MANY MANY lives lost" and "AI drivers, fewer lives lost". What would archagon have us do? Not have AI drivers until a perfect solution is possible? The "crash-unavoidable" scenario is an unavoidable reality as long as stopping distances/acceleration/reaction times a…

Is your friend/loved one more valuable than the 90 other people who die in automotive accidents (in the U.S. alone) daily? Your attempt at "humanizing" the situation is merely being dismissive of the values of others' lives. Everyone who dies is special and important to someone. To wring your hands and rail against utilitarianism is to try and apply tribalism to moral reasoning. Because this person matters more TO YO…
To me, the key factor is blame. Who do we fault in an accident? We can't imprison an algorithm or put it in jail. But we can implicate a careless driver. A loved one should not have to die because a truck happened to be the right shade of white — not without much discussion and the possibility of legal recourse.
There are many horrible, systemic things we could do to improve the lives of the majority at the expense of a few. In the end, we usually determine that the rights of individuals outweigh the utilitarian benefit. Does the same reasoning apply to self-driving cars? I don't know. If the technology proves as safe as people make it out to be, maybe things will end up OK. But it's not a closed case by any means.
