Waymo's driverless robotaxis are being credited with 82% fewer injury-causing crashes than human-driven vehicles, according to newly highlighted safety data. The figure is fueling debate about whether autonomous vehicles are now safer than human drivers, and how quickly robotaxi services should expand into more cities as regulators and the public weigh the evidence.
