Thinking just a little further, once the autonomy of the vehicle is good enough, there's no need to park the vehicle at all - you just tell it to start driving to a dealership or an owner's home. There'd be some additional logistics to figure out how to recharge the vehicle as necessary on route, but that's a very different problem, and probably also amenable to automation.
