Waymo's self-driving robotaxis have shown a strong safety record, with most accidents attributed to human error or external factors, yet their cautious approach contrasts with the rapid development seen in other AI sectors. As the company expands its services to new cities, it faces the challenge of proving reliability in diverse driving conditions while navigating potential risks that could jeopardize its future. The long-term vision includes embedding Waymo's services deeply into American transportation infrastructure.

The National Highway Traffic Safety Administration has initiated a preliminary investigation into approximately 2,000 Waymo self-driving vehicles due to reports of the robotaxis failing to stop for a school bus with flashing lights and an extended stop arm. Waymo has stated that it is implementing improvements to address this issue and emphasized its commitment to child safety.
