To me the question is relatively uninteresting because it seems obvious.

As long as cars belong to individuals they have the responsibility to favor the interests of those individuals as far as law permits. Where and how much the community is to be preferred over the individual, the community should specify in laws. People running code that breaks those laws should be liable for that codes actions. (I could imagine an ethics slider settable at the owners choice within the legal limits that allows them to discount the lives of the passengers compared to the lives of others, on the condition that they notify their other passengers).

It's possible that ultimately the right choice is to move to a different model, but in that case, the AI should not be owned by the individual who bought the car and has a reasonable expectation that it work on their behalf.

The ethical decision on the car is no different than the ethical decision that we ask the human driver to make in similar situations (which as the gp noted are incredibly rare), or that we trust the human driver to make when we are passengers in their car. In fact I even doubt that it makes sense to legislate it, since we haven't so far for e.g. uber drivers, but perhaps testing will indicate that we should.

In terms of the speed limits, society has already decided to accept a huge number of deaths per year that would almost all be preventable with a speed limit of 35mph, so I don't see how the introduction of AI drivers affects this question.

I would like to see laws that say that all source code for self driving cars must be publicly auditable and pass tests before being approved for road use. Running code that has not been safety tested by the state will leave you uninsurable and personally liable for its actions. We should aim to make running the test suite as accessible as possible in order to allow innovation, but it should still give us a high confidence that the driver behaves correctly according to the law.

I take pretty much all of this from analogy with human drivers: when we're driven by someone else, we have relatively little control over their ethical slider setting, we have high speed limits for humans because we think the convenience of the many is more important than the lives of the few, we don't let brand new humans drive without having some indication that they'll make the right decisions. None of these problems seem to be particularly changed by the introduction of AI.

Well put. I would not buy a car that wasn't designed to protect its occupants first and foremost. My family is more important to me than abstract, unlikely to occur ethical dilemmas.

Having that choice programmed in actually makes it easier for self-driving cars to predict the behavior of other cars on the road. It's simple and probably at least a near-global maxima for optimal car fitness.

Have you even been in a Taxi? Or a bus? Or any situation where someone who is not you is driving the car?

You have put your life into their hands when you do this.

No matter what algorithm the self driving car is running, it is going to be 100 times safer than you driving the car. Yes, YOU are a worse driver than a self driving car, NO MATTER what "ethics algorithm" it is running, because any of the ones that could be running will be safer than you or the taxi driver.

What you are basically saying is that "I don't trust any braking system in my car that isn't 100% perfect, therefore I am going to drive my car without ANY braking system! I'll physically stop the car myself if I ever need to brake!"

No matter what algorithm the self driving car is running, it is going to be 100 times safer than you driving the car.

And yet, I have driven hundreds of thousands of miles over many years under all kinds of road conditions without ever having an accident. Statistically my record is better than many, but it's hardly a unique achievement among experienced drivers who are careful.

Tesla's Autopilot probably has done more than 100x the miles I have by now, but it's also had several accidents, some of them fatal. As I understand it, it has also only been used on highways, which are statistically much safer and have much less challenging driving conditions than places like winding rural roads or inner city residential areas.

As another example, Google's self-driving cars have apparently done less than 10x the driving miles I have, but under somewhat more challenging conditions than highways. They too have had accidents, and they too reportedly still can't cope with anything close to truly realistic driving conditions on their own.

So no, it appears that the state of the art in self-driving technology today is not 100x safer than me driving a car. If anything, it's looking considerably more dangerous. Of course there is potential there -- no matter how skillful and careful I am, I still only have two eyes and human reaction times -- but automated driving is still a long way from outperforming good human judgement as things stand today.

But are self-driving cars better drivers than some identifiable other group of people than you? E.g. Legal but elderly drivers with poor sight.

Are the algorithms a useful helper for some drivers?

I really really want all our rental vehicles to remind the drivers if they are on the wrong side of the road (we get multiple deaths every year from Americans and Europeans driving incorrectly in our small country).

I expect that with time these self-driving algorithms will become safer than an increasing proportion of human drivers. I'm just very wary of assuming they are better than most or all human drivers prematurely.

We as a society have a habit of putting too much faith in technology. Most of us aren't knowledgeable and unbiased enough to assess its risks objectively, particularly in areas where there is a very low chance of something happening but it will be very bad if it does happen.

> No matter what algorithm the self driving car is running, it is going to be 100 times safer than you driving the car.

That seems very suspect.

I think that you highly underestimate how bad humans are at driving.

Being better than a human driver is a very low bar to pass.

Being 100x better than a sober, attentive human is a very high bar to pass.
You're assuming most drivers on the road are attentive.
False equivalence.

If you get into a taxi or a bus, there's still a human driver who has the same survival instinct that you have. If he has to run someone over so that he can survive, he likely will, saving you too in the process.

This isn't about systems being perfect, it's about whether the system should err on the side of protecting the car's occupants or on minimizing casualties overall.
