Waymo has released new data indicating that the Waymo Driver continues to make roads safer in the places in which we operate.

A new analysis covers over 170 million fully autonomous miles—an equivalent of 200 human lifetimes of driving. The data shows that regardless of fault, the Waymo Driver was involved in 92% fewer crashes that cause serious or fatal injuries than human drivers in the same driving conditions. Our Driver was also involved in 83% fewer crashes where airbags are deployed, and 82% fewer crashes involving any injuries at all.

At our current scale, driving over 4 million miles weekly, our analysis suggests the Waymo Driver is preventing approximately one serious-injury crash every 8 days. Some medical professionals argue that this kind of safety record represents a public health breakthrough that could make significant contributions to reducing the likelihood of road traffic deaths and the impact of crashes.
