Tesla FSD v14 drives too well, raising safety concerns over reduced driver vigilance

Tesla’s latest driver-assistance system, Full Self-Driving (FSD) v14, shows marked performance gains but may create new safety risks by lowering driver vigilance, analysts say. As a Level 2 system, it still requires constant monitoring and readiness to intervene. Some drivers report difficulty staying alert after hundreds of miles without intervention. Researchers cite “vigilance decrement” and studies suggesting 5 to 8 seconds to refocus when retaking control.
