Uber launches self-driving vehicles in Pittsburgh

The ride-sharing service rolled out its first fleet of four autonomous vehicles, which come equipped with an Uber driver and an engineer in the front two seats who intervene occasionally, Reuters reports.

The Ford Fusion cars have 3D cameras, global positioning systems and a detection system that uses lasers to assess objects on the road. The vehicles can stop at red lights, go at green lights, drive over bridges and maneuver around other vehicles on their own.
