Floods Reveal a Hidden Flaw in Self-Driving Decision Making

Waymo’s flooded-road incident shows a perception-to-action flaw: sensors clearly detected water and the car slowed, but the decision stack chose a risky continuation, prompting a recall of 3,791 vehicles while a permanent fix is developed. The piece contrasts sensor architectures across platforms (Tesla Vision, Uber Avride, Zoox) to illustrate how each handles water hazards and edge cases, underscoring that riders must know which system they’re on and whether flood-detection logic has been patched.
