Waymo expands driverless fleet amid safety and edge-case challenges

Waymo, an Alphabet subsidiary, is expanding its driverless vehicle deployment, currently operating nearly 4,000 cars across 15 cities and completing approximately 500,000 paid trips per week. Company data indicates that Waymo’s vehicles experience 94% fewer serious-injury crashes compared to human drivers. An Insurance Institute for Highway Safety study corroborated this, finding Waymo vehicles were involved in 68% fewer police-reportable crashes per mile than human-driven vehicles in several major U.S. cities.

Despite these safety statistics, the industry faces challenges with “edge cases,” such as freeway construction zones, emergency scenes, and unusual road layouts. Waymo recently recalled 3,871 autonomous vehicles following issues with driving systems in construction zones. Additionally, the National Highway Traffic Safety Administration has documented instances where driverless vehicles interfered with law enforcement and first responders.

In the broader market, Waymo leads in unsupervised paid rides, followed by Baidu in China, which operates approximately 1,000 driverless cars in Wuhan. Amazon-owned Zoox has also begun offering paid rides in Las Vegas with 100 driverless cars. Tesla operates robotaxis with safety drivers, while companies like Motional and Wayve continue to develop services that currently require human safety drivers.
