IIHS Finds Waymo Safer Than Humans—With Notable Data Caveats
The IIHS study reports Waymo driverless taxis had a substantially lower crash involvement rate than human drivers overall (68% lower, with city variations) based on cleaned data from 2021–2024. However, the dataset is very small and selectively cleaned—only 89 Waymo crashes with automation out of 736 incidents, and mileage data is available only for Waymo—raising questions about statistical significance and underscoring the need for better data collection on L4 vehicles.
