* Why would it have to go home? It could just drive out of town to any cheap loitering lot. * Why not put it to work. It could transport people or packages during that time. * Mostly, in such a future, you probably won't own a car. You'll rent or lease access, and the price to take a nice autonomous mini-bus will be super low while remaining convenient.
