Then I realized what they were: Waymo driverless taxis. Now, a new study from the Insurance Institute for Highway Safety (IIHS) has released impressive data on Waymo's safety record that may put critics to rest. The study examined around “50 million autonomous miles driven by Waymo vehicles,” according to Kelly Blue Book. The research also found that Waymo vehicles experienced 85% fewer single-vehicle crashes and 81% fewer injury crashes compared to human drivers. Researchers reported driverless vehicles “don't get distracted, impaired, fatigued, or drowsy”, all factors that typically contribute to crashes where human drivers are behind the wheel.
