 "notes": "Sensor redundancy assumes independent failure modes. Glass defeats all three at once — it is transparent to cameras, poorly reflective to lidar at angle, and acoustically weak — so three sensors gave one wrong answer. Redundancy protects against random faults, not against a shared blind spot. Verified quote is the AI Incident Database summary. Pairs with the Coco shelter crash two days later.
