The science fiction idea of all traffic consisting of autonomous vehicles lowering traffic accidents, is nearing a reality. Waymo released intro of data documenting nearly 100,000,000 miles of cars driven, and the numbers show significant safety outcomes.
The self-driving car company Waymo recently released data covering nearly 100 million driverless miles in four American cities through June 2025, the biggest trove of information released so far about safety. I spent weeks analyzing the data. The results were impressive. When compared with human drivers on the same roads, Waymo’s self-driving cars were involved in 91 percent fewer serious-injury-or-worse crashes and 80 percent fewer crashes causing any injury. It showed a 96 percent lower rate of injury-causing crashes at intersections, which are some of the deadliest I encounter in the trauma bay.
