My Herky-Jerky Ride in General Motors' Ultra-Cautious Self Driving Car

Nothing will make you hate humans--capricious, volatile, unplanned, erratic humans--like sitting in the back of self-driving car. When I hitched a ride in one, a white and orange General Motors Cruise autonomous vehicle during a press event in San Francisco on Tuesday, every movement was a cause for alarm. Two walkers darted out in front of the car during my roughly 20-minute, 3-mile ride, blissfully ignorant that they were trusting their lives to a piece of software. Two cyclists made unexpected but sweeping turns. Human-operated vehicles whipped around corners and rolled through stop signs.
