THIS WEEK, WE learned the future of the car is not owning one—at least not if Uber gets its way. The ride-hailing giant came out with twin announcements: On Monday, it said it would acquire the bike-share company Jump, in a deal worth $200 million. On Wednesday, it announced a move into car-sharing and public transit ticketing, too, inking deals with the startup Getaround and the British mobile payments company Masabi. The goal: Making it much, much easier to live car-free, and maybe take a few UberX rides along the way.
