A driverless Waymo car collided with a cyclist in San Francisco on Tuesday but the bicyclist suffered only minor scratches and left the scene on their own, the company said by email.
Waymo, Alphabet's autonomous driving unit, said it called the police to the scene and that it was also contacting relevant authorities about the incident.
Waymo said its vehicle was at a complete stop at a four-way intersection when a large truck turned into the intersection. At its turn to proceed, the Waymo car moved forward.
However, the cyclist was behind the truck and not visible as they crossed into the Waymo vehicle's path.
When the cyclist was fully visible, the Waymo's vehicle braked heavily, but was not able to avoid the collision, the company said.
