Will Driverless Cars Become the New Road Rage?

It’s a late summer day, and I’m sitting in the driver’s seat of a BMW 3 Series at the Mazda Raceway Laguna Seca in Salinas, Calif. Sitting, not driving. When I lift my hands from the wheel at the beginning of this 2.2-mile course, the car accelerates to 75 mph almost instantly, pushing me and my passengers—BMW engineers and executives—into our leather seats. The car’s computer brain, using satellite signals to navigate the track, is in control.
