Rules were made to be broken. Unless you're up against, say, special prosecutor Robert Mueller or the frightful might of the Federal Aviation Administration. Turns out that in transportation, like so many other things, regulators can serve as a thick, strong wall, crushing even the most delightful (or horrifying) of innovations with the weight of concrete. Observe Uber's self-driving car program, which, as senior writer Jack Stewart explains, will definitely have to contend with the FAA before it gets off the ground. Or the shaky future of new and potentially life-saving semiautonomous vehicle tech in the US, which carmakers are loath to unleash in a country without firm rules about licensing and liability.

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. Meanwhile, Airstream rolled out an adorable and very practical new trailer that is, perhaps, too small to share with too many honies, and the Silicon Valley–based lidar startup Luminar shared its newest tech with transportation editor Alex Davies.
