Members of the US Congress have cast doubt on the safety assertions made regarding Tesla's Full Self-Driving (FSD) system. Specifically, two federal senators have penned a letter to the National Highway Traffic Safety Administration (NHTSA), pressing for a thorough reassessment of the safety data, especially the bold assertion that the FSD system is "seven times safer than human drivers." This request stems from concerns over statistical validity, measurement methodologies, and the integrity of data collection processes. Furthermore, the senators have advocated for enhanced data reporting standards within the autonomous driving sector and have set a deadline of July 7 for a response.

Previously, the California Department of Motor Vehicles determined that Tesla's use of the term "Autopilot" was deceptive, leading Tesla to cease its application. In contrast, overseas regulatory authorities, such as those in the Netherlands, have granted approval for FSD access based on independent real-world testing, concluding that its safety performance exceeds that of human drivers. Concurrently, New Jersey is contemplating the implementation of strict regulations on autonomous vehicles, a move that Tesla opposes and has actively petitioned against, arguing that such legislation would impede industry progress. On the other hand, Texas has already permitted the compliant operation of Tesla FSD vehicles and driverless taxis.

At present, the NHTSA has commenced a review procedure, while individual states maintain jurisdiction over the expansion of Tesla's autonomous vehicle operations.
