 If you decide you need to go to the dentist at 12pm, simply open up your Tesla app and schedule your own car to pick you up at 11.30am. Or let your car keep running money and rent someone else's car. If you go to the movies for two hours, you can have your car drop you off and go earn some money while you watch the latest Marvel film. But just like you no longer own your vacation home because you can rent one on Airbnb, most people will like to choose not to own cars. Large companies will own huge fleets and small entrepreneurs will build up their own mini collections.
