US agency upgrades probe into Tesla vehicles

The National Highway Traffic Safety Administration (NHTSA) has escalated its investigation into 3.2 million Tesla vehicles equipped with the Full Self-Driving (FSD) driver-assistance system. This upgrade stems from concerns that the system may fail to adequately detect or warn drivers in conditions of poor visibility. The agency initially launched a preliminary evaluation into the system's performance, and the subsequent escalation indicates a more rigorous examination of potential safety deficiencies. This action underscores the ongoing regulatory focus on the safety and reliability of advanced autonomous driving technologies.
