Waymo's 220 Million Autonomous Miles: 94% Fewer Serious-Injury Crashes Than Humans

Waymo's safety data spans 220 million fully driverless miles through March 2026. Compared to human drivers in the same cities, the Waymo Driver had 94% fewer serious or fatal-injury crashes and 82% fewer airbag-deployment crashes. UMTRI's Carol Flannagan says Waymo's mileage is now sufficient for credible direct crash-rate comparisons to human drivers. Full methodology is published at waymo.com/safety/impact.
