New data shows that the Waymo Driver continues to make roads safer. Over 14.8M rider-only miles driven through the end of March, it was up to 3.5x better in avoiding crashes that cause injuries and 2x better in avoiding police-reported crashes than human drivers in SF & Phoenix. 
Comparing AV and human drivers’ crash rates is not a trivial task. Last December, we introduced clear human benchmarks for such analysis and showed that the Waymo Driver significantly outperformed them over the first 7M+ rider-only miles.
New data provides more evidence for the Waymo Driver’s safety benefits. In San Francisco alone, where we’ve clocked 3.83M rider-only miles, Waymo’s driving resulted in 17 fewer injuries and 12 fewer police-reported crashes.
In Phoenix — our first ride-hail city where we’ve historically driven more miles — Waymo’s impact on road safety is even larger: 13 fewer injuries and 20 fewer police-reported crashes compared to human drivers.
By sharing this safety data, beyond regulatory reporting requirements, we hope to enhance transparency and foster trust with our riders and communities we drive in. Learn more about our safety research at and stay tuned for more safety updates soon.waymo.com/safety
