This is all mostly orthogonal with the feasibility or even desirability of fully self-driving vehicles. For commercial vehicles (taxis, buses, delivery, trucking, etc) they are a real solution to cost and productivity, which could potentially have ripple effects on private car ownership, parking space, etc. For private vehicles they can free the driver who can then do something else like you would in a taxi or public transport. For instance, if cars drive themselves then the operating costs of a private car and a taxi are the same so we could imagine that taxi fares would drop. Now if indeed people work from home more and don't need to drive everyday then perhaps not owning a car but insyead to summon a self-driving taxi when needed would make sense.
