Waymo crashes 1/3 as much as a human driver, says IIHS

Waymo’s driverless cars crash about one‑third as often as comparable human‑driven vehicles, according to a new Institute for Highway Safety (IIHS) analysis released this week. The IIHS examined robotaxi performance in four U.S. cities and recorded a 68 % drop in crash frequency versus human drivers. The Drive detailed the study’s methodology, noting that the data set covered Waymo’s autonomous fleet operating as robotaxis.

CBC emphasized the 68 % reduction, while Electrek quoted the IIHS summary that Waymo crashes at roughly one‑third the rate of conventional drivers. Jalopnik’s commentary suggested readers must ‘squint’ at the data to see the safety gap, and Yahoo Autos framed the findings as part of the larger question of whether machines are taking over. The overall coverage presents the numbers as a strong safety signal for Waymo’s robotaxi service.

The coverage does not specify crash severity, total mileage driven, or the selection criteria for the four cities, and it restricts its analysis to robotaxi operations. The report also omits any comparison of minor versus major incidents, so the overall safety impact remains unquantified. Analysts note that without those details, projecting the result onto all autonomous deployments remains uncertain.
