Self-driving car crashes can trigger a complex blame game

It was morning in San Francisco on December 7 of last year, and a self-driving car and a motorcyclist were both motoring down Oak Street. The autonomous car, a white 2016 Chevy Bolt, started to make a lane change to the left from the center lane, then aborted it—the gap it was moving into shrank. When it slid back into the center lane of the three-lane street, it collided with a motorcycle that had been passing on the right. The motorcycle and its rider fell to the ground.
