Those computers probably won't get into situation like this in the first place, being able to stop or react preventive. Anyway, it will be so rare an occasion with no guaranteed outcome (it's all about probabilities), so it's not really matters as much as it's discussed. With same kinda of attention you could ask if making and selling ladders is ethical, because people fall from them and hurt themselves.

It will always be the case that circumstances can change faster than something with the momentum of a fast moving car could adapt. Somewhere between "you're boned" and "your car saves the day" lies room for a scenario such as this, with potential room for a large amount of thinking.

I agree that it will be rare, and that the concern is overblown. That said, "it's all about probabilities" is no reason something can't be vitally important.

I think there is a substantive difference between the two. We're not asking whether selling a car that has a chance of injuring the user is ethical - we're fine with that. We're not even asking whether selling a car that has a chance of hurting others is ethical (already meaningfully different than the ladder case). We're asking about the ethical ramifications of making particular tradeoffs in "chance to hurt the user" versus "chance to hurt others". It's an interesting question, so it gets a lot of attention. I don't think most of those involved see it as a reason to prevent self-driving cars - long before the dilemma is really relevant, self-driving cars are already safer than human driven.

I think it's possible that with improving AI of self driving cars, making overall safety better, there will be ≈0 occasions when car simultaneously 1) doesn't have time to react to some sudden problem and 2) has time to make informed decision (and physically perform it) on how many people to save. Especially if pedestrian airbags become popular.
Even if, the car will have to calculate whether it has enough clearance to deploy the wings so that it doesn't cut down a pedestrian, or whether there's anyone that could be caught in the engine wash.
Interesting as it may be, it's only shifting the problem ;).
Yes, but perhaps less than you think. I fly small aircraft, and the one we fly gets ~15 mpg in cruise carrying up to 6 people at just over 200 mph. There are cars/trucks on the road that get less than that. If I slow it down to 150 mph, I can get over 20 mpg.
