Lost in Fog: Sensor Perturbations Expose Reasoning Fragility in Driving VLAs
Researchers evaluated Vision-Language-Action models in autonomous driving under sensor degradation, finding that explanation consistency (Chain-of-Causation) strongly correlates with trajectory reliability. When model explanations change due to perturbations like fog or noise, trajectory errors increase 5.3x, suggesting reasoning consistency could serve as a safety monitoring tool for autonomous vehicles.
