Waymo paused operations in Atlanta, San Antonio, Dallas and Houston after multiple robotaxis entered flooded roadways, including one vehicle immobilized for an hour in Georgia despite prior software restrictions. NHTSA documents confirm the company had not completed a final remedy for flood avoidance at the time of its May recall, relying instead on temporary geofence limits tied to National Weather Service alerts. This Atlanta event occurred before flash-flood warnings were issued, exposing reliance on external signals that lag real-time conditions. Analysis of prior incidents shows the same pattern: the school-bus passing fix issued after 2024 detections failed to eliminate repeat violations, prompting NHTSA’s second data request on May 15 and parallel NTSB scrutiny. The January Santa Monica collision with a child further illustrates incomplete edge-case handling, with the vehicle only reducing to six mph before impact. Cross-referencing NHTSA’s ongoing investigations and Bloomberg’s initial reporting on the Texas pauses indicates that current deployment strategies prioritize rapid geographic expansion over validated performance in precipitation extremes documented in multiple regulatory filings.
