I don't think liability is that key here. cost of damages = # of accidents * cost per accident - Self driving cars should reduce the number of accidents - Cost per accident seems independent of the kind of car you drive. If a human driven taxi hits me, I can sue the taxi company. If a self driven taxi hits me, I can sue Google. I should be able to sue for the same amount in either case.
