>How about saving human time that would otherwise be spent on driving?

There may be solutions for your wasted time driving that not costs more human lives, like public transport. An AI is will never have the intuition of a human brain, so you can try compensating with better sensors and faster reaction time, but if you have worse sensors and reaction time then a human then you do not have a self driving car yet, such toy projects were made by students years ago.
