Waymo autonomous vehicles were engaged in 68% fewer accidents than human drivers across four U.S. cities over a three-year span, as indicated by recent findings from the U.S. Insurance Institute for Highway Safety. The study revealed 89 police-reportable crashes involving Waymo in San Francisco, Phoenix, Los Angeles, and Austin between 2021 and 2024, while human-caused crashes in the same locations totaled 901,525 during the same period, excluding interstates and highways.
Steven Waslander, the director of the University of Toronto Robotics Institute, not part of the study, expressed excitement about seeing long-anticipated technology like this being implemented on a substantial scale in real-world scenarios. Of the 89 Waymo-involved crashes, 72% occurred when the vehicle was entirely autonomous, with approximately half of the incidents involving passengers.
The study highlighted that Waymo covered about 80 million kilometers of driverless operation, significantly less than the 355 billion kilometers driven by humans in the same places over the three-year timeframe. The crash rate per million vehicle miles traveled was 1.28 for Waymo vehicles and 4.06 for human drivers, marking a 68% lower crash rate for Waymo.
Alphabet’s autonomous vehicle study used data from police reports, Waymo, and federal databases. According to the U.S. Department of Transportation, crashes involving self-driving vehicles must be reported promptly under specific conditions.
Waymo is currently operational in 11 U.S. states and has intentions to expand to the United Kingdom and Japan, with plans to establish programs in Canada. Despite the positive outcomes for Waymo in the study, concerns remain about data transparency and the readiness of governments to embrace autonomous vehicle technology fully.
While Waymo is making strides in advancing autonomous technology, challenges persist in entering the Canadian market due to regulatory hurdles and climate differences. Waymo’s progress is being closely monitored, and public trust in the reliability and safety of driverless vehicles continues to be a key consideration for future adoption and expansion.
