Waymo's Flood Blind Spot Exposes Robotaxi Safety Gap

Waymo's self-driving vehicles lack reliable ways to detect standing water and flooded roads—a failure of sensor fusion, not individual technology. The harder problem: edge cases tied to environmental conditions (rain, flooding, snow) remain algorithmically unsolved because training data skews toward clear weather, and no single sensor (LiDAR, radar, camera) can reliably distinguish passable wet pavement from dangerous water hazards. Until robotaxis navigate weather-dependent obstacles the way human drivers do—through learned pattern recognition and risk intuition—their operational domain will remain confined to specific geographies and seasons, not the anywhere-anytime promise investors have funded.
