Maven, which the company announced Wednesday. At first glance, you might consider this an odd move. Maven is available only in Ann Arbor, Michigan—though GM plans to move into other cities soon—and it doesn’t offer the convenience of Uber or Lyft. Oh sure, there’s money to be made in car-sharing, as ZipCar and others have shown. But it’s small potatoes for a company like GM. It isn’t until you take the long view that this move makes sense. Maven can be the foundation for the self-driving car network GM wants to build.
