This will only become more common once vehicles are self-driving. People will live in their vehicles and have them either drive around all night or find a place to park many hours away from their jobs (assuming there any jobs left).

The fantasy many folks seem to have about self-driving vehicles causing car ownership to disappear in favor of automated Ubers/Lyfts/whatevers on demand might come to pass for one class of people, but there will be large numbers of people for whom the opposite happens: they give up their homes (by choice or not) and live in a self-driving vehicle that is the only dwelling they own.
