NHTSA upgrades Tesla FSD probe to engineering analysis amid reduced-visibility safety concerns
The U.S. NHTSA has escalated its investigation into Tesla’s Full Self-Driving system to an engineering analysis, examining potential safety defects when FSD is used in fog, glare, or other reduced-visibility conditions across about 3.2 million vehicles, after crashes where the system reportedly failed to detect hazards until close to impact, including a fatal pedestrian collision.
