who cares who is liable for automated cars, this is what insurance is for. insurance companies will adapt.
do you sit there worrying now who is liable if YOU suddenly decide you have no idea whats going on and cause an accident?
now if you are concerned about the safety of an automated care, which is sounds you are, that is a different matter, but the liability argument really doesn't seem to interesting. i am already liable for my car how does that really change with a self driving car?
now what if it is proven that self driving cars have a better safety record than human drivers?
