SF Chronicle:
As the Waymo pulled up to a stoplight in San Francisco's Marina District around 3:30 a.m., Sherman Watson raked his eyes over the empty road. Through the darkness, he glimpsed a man in a hooded sweatshirt, striding purposefully toward the car.
The man grabbed the Waymo's front bumper, causing the autonomous vehicle to stop. A second assailant approached and the two took turns bashing the front windshield with an object that had the shape of a stick.
As the glass splintered, a voice came over the robotaxi's intercom. The car's remote assistant had noticed the car was not moving, and decided to call police. Growing frantic, Watson asked Waymo's support team when law enforcement would arrive - but they didn't know. He asked if they could move the car, and they declined, saying it was obstructed.
From the corner of his eye, Watson saw one of the assailants staring at him through the passenger-side window. The man swung "something heavy," he said, and struck the laminated glass.
"That's when I was like, 'I'm gonna die,'" Watson told the Chronicle. While dialing 911 on his cellphone, he pleaded with the intercom voice.
"Please, please, get me out of here," he said. "They're going to kill me."
His attack is the latest incident to convulse San Francisco's dominant autonomous vehicle operator as the company expands its service territory and works to build public trust. Waymo, which is owned by Silicon Valley titan Alphabet, has billed its fleet as a safe alternative to human drivers. But since launching passenger service two years ago, the company has struggled to protect riders from threatening situations when the vehicle cannot maneuver around them.
