# "IIHS released a 25-page autonomous vehicle study finding that Waymo L4 vehicles in driverless operation had police-reportable crash involvement rates 68% lower than human drivers in the same areas. Waymo's rate of rear-ending another vehicle was 91% lower. Waymo's rate of being rear-ended was 40% lower. 22% of L4 crash involvements were deemed police-reportable; two-thirds occurred in driverless operation. L4 vehicles were unlikely to be the striking vehicle. Data from federally required reports, state police databases, FHA VMT data, and Waymo." (DEPLOY verdict: Open)
