Waymo Halts Atlanta Robotaxis After Flood Recall Fails to Prevent New Incident

Waymo has suspended operations in Atlanta after one of its driverless vehicles drove into a flooded street and became stuck for roughly an hour during a heavy rainstorm. The pause comes just a week after the company issued a software recall for the same problem and follows a similar suspension in San Antonio. Waymo acknowledged in NHTSA filings that the recall did not deliver a complete fix — only interim restrictions on high-risk roads — and blamed the Atlanta incident partly on flooding that outpaced National Weather Service alerts, which the company uses as one input for weather-aware routing.

The episode highlights a recurring pattern at Waymo: shipping a fix that fails to fully resolve the underlying behavior. The same dynamic played out last year when a patch meant to stop robotaxis from illegally passing stopped school buses failed to hold, an issue now under active investigation by both the NHTSA and NTSB. A separate investigation covers a January crash in Santa Monica where a Waymo vehicle struck a child at low speed.

For a company scaling driverless service across multiple US cities, the flood failures point to a harder problem than a single bug — perception and planning systems that cannot reliably detect standing water, combined with weather signals that arrive too late to matter in fast-moving storms.
