Yes, the choice it makes won't be based on ethics, that will ultimately come down to programmers and how well they can train the ai systems to recognize and choose the option with the least human injury. Although programmers will of course try to train it to do that. So maybe the ethical choice is actually further up the chain where people make the decisions on whether or not the AI is good enough. I don't think I that will be accepted by regulators/society until it can be demonstrated that AV's are undeniably safer-- not just as good as human drivers, much much better. Right now it's newsworthy whenever a Tesla auto pilot drives into a barrier. We'll need to get to a point where not only does that not happen, but also that it becomes newsworthy every time an AV saves a life-- swerving out if the way faster than any human reflexes could have reacted to avoid an accident, or a child chasing a ball into the street, etc.
