The recall affects nearly 3,800 vehicles, primarily impacting Waymo's operations in cities across the United States. The incident raises concerns about the ability of autonomous vehicles to safely navigate hazardous conditions, such as flooded roads, without human intervention. While no injuries occurred in this case, the potential risks of such failures include vehicle damage, passenger safety concerns, and broader public trust in self-driving technology. The recall also comes amid increased scrutiny of Waymo's systems, as NHTSA is separately investigating an earlier incident involving a Waymo vehicle striking a child in Santa Monica, California.
