Waymo has suspended its robotaxi service in Atlanta and San Antonio as the company addresses ongoing issues with its autonomous vehicles driving into flooded roadways.

The Google-owned company confirmed that operations in both cities have been paused while engineers work to resolve the problem. The suspension affects Waymo's commercial ride-hailing service that uses self-driving vehicles to transport passengers.

The flooding-related incidents highlight ongoing challenges facing autonomous vehicle companies as they work to navigate complex real-world driving conditions. Flooded roads present particular difficulties for self-driving systems, which rely on sensors and mapping data to make driving decisions.

Waymo has not provided a timeline for when service might resume in either city. The company operates robotaxi services in several other markets and has been expanding its commercial operations in recent years.

The suspension comes as autonomous vehicle companies continue to refine their technology to handle various weather and road conditions that human drivers typically navigate through visual assessment and experience.
