CRASH: Cognitive Reasoning Agent for Safety Hazards in Autonomous Driving

Researchers introduced CRASH, an LLM-based agent that analyzes autonomous vehicle incidents from NHTSA data covering 2,168 cases and 80+ million miles driven between 2021-2025. The system achieved 86% accuracy in fault attribution and found that 64% of incidents stem from perception or planning failures, with rear-end collisions comprising 50% of all reported incidents.
