1) Expecting a human to be on deck within some fraction of a second in challenging times will not fly.
2) Perhaps software in cars can be independently safety tested. Just like cars are collision tested today.
3) Understand about human reaction times. My question is about making moral choices: hit a pedestrian or sacrifice the driver?
If it was a case of hitting a pedestrian versus driving off a cliff I feel like the pedestrian will just be SOL for getting in that situation. Otherwise you could have murder by car relatively easily.
Maybe we could make people register their car settings at the DMV like we do for organ donations. "Would you like to opt-in to the murder-children AI driver, or the martyr driver?"
