I should point out that the guy I linked is an AI lawyer, so the replies aren't actually as valuable input in this case… also, I think he uses "evade" to mean "not hitting something" so braking still counts.

I've had other discussions with literal self-driving car company engineers where they told me it's not a real problem as usually defined. Though I can't link those, here's one where someone asks the Aurora people about it.

> So braking is clearly not the only option.

It's the best option because you're not the only moving thing on the street. Braking in response to a car in front of you is normal, but evasive maneuvers at speed aren't. You don't know what other people are going to do in response to that.

Oh, but I will let you turn or reverse as long as you signal first. I just don't think you should do it at speed with no warning even in a "least bad option" situation.

> You seem completely blind to the real world issues that driving (among other things) forces onto a system.

Sorry for being a theoretical murderer, but you weren't talking about real world issues, you're talking about a trolley problem! That's defined as:

- there's 2+ discrete paths you can take. (semi-true for cars)

- there really is something on each path you'll hit. (semi-true, in reality they'd react to you in good and bad ways)

- your knowledge about this is correct. (not true, SDCs' world-knowledge is not perfect)

- you are going fast enough to be dangerous. (semi-true, SDCs will drive at safe speeds more often)

- you must go forward. (not true, SDCs can brake or reverse)

#3 and #5 being the big problems making this unrealistic.

Maybe a real world problem would be driving on a mountain road and there's a boulder about to fall on you? In that case, I agree braking would not be safe.
