I understand that this is the problem posited by this and many other articles. But right now we are almost certainly not even considering asking these questions of a self-driving car. It doesn't have remotely the situational awareness and data to make an informed decision, let alone the capacity. I would be surprised if any of the first several generations do anything beyond trying to avoid a collision. Including lowering velocity much below what a human might in adverse conditions. After that I expect that mitigating collision impact on the vehicles will be the next problem, since that is an engineering one. Such as optimal crash angles, etc. We are a long way from our cars making deliberate life-or-death moral decisions. Before we get there we have many decisions they can make very effectively that have no moral component. Once their decisions begin taking into account morality, society will no doubt legislate, but let's worry about that then.
