Author: Ryan Felton U.S. federal safety regulators are intensifying oversight of Tesla's driver assistance system, following concerns about the system's handling capabilities in adverse road conditions. The National Highway Traffic Safety Administration (NHTSA) announced on Thursday that it will upgrade its investigation into the Full Self-Driving (supervised mode) system. This system can control vehicle driving and steering but requires drivers to continuously monitor road conditions. NHTSA has confirmed multiple collision incidents (including one fatal accident) in which the Full Self-Driving system failed to adequately warn drivers about low visibility conditions such as glare from bright lights, fog, and airborne dust. The investigation was initially launched in 2024 to assess whether the system can respond appropriately in the aforementioned scenarios. NHTSA stated on Thursday that it has upgraded the investigation to the "engineering analysis" phase. This is a more in-depth review of potential safety defects that could ultimately lead to recalls or other enforcement actions. Tesla has not immediately responded to requests for comment. This investigation is the latest review by NHTSA of the Full Self-Driving system. A month later, Tesla is expected to launch a driverless taxi named **Cybercab**, which will not be equipped with a steering wheel, pedals, or other traditional control devices, relying entirely on the Full Self-Driving system for autonomous driving. Tesla has stated that the Cybercab will be used as an autonomous taxi and sold to the public, claiming that the widespread adoption of fully autonomous vehicles is key to its transformation from a traditional automaker to a giant in artificial intelligence and robotics. As the highest automotive safety regulatory agency in the U.S., NHTSA has been continuously reviewing Tesla's driver assistance technology over the years while also overseeing similar systems from its competitors. Driver assistance systems like Full Self-Driving require drivers to remain attentive at all times and take control of the vehicle when prompted by the system. NHTSA has been evaluating whether drivers receive adequate warnings when the system disengages. Regarding Tesla, NHTSA is particularly focused on the unique design of its Full Self-Driving system — which **relies solely on cameras** and employs a "pure vision" approach. Unlike Waymo's fully autonomous taxis and the driver assistance systems of other emerging competitors, Tesla does not use radar or lidar (an optical system that allows vehicles to perceive their surroundings more comprehensively). NHTSA stated that after Tesla transitioned from a "camera + radar" approach to a pure vision system in mid-2021, it equipped both new and old vehicles with a "performance degradation detection system" through software updates. Regulators noted that Tesla began developing an updated version of this system in June 2024, but as of now, NHTSA is unclear whether the relevant vehicles have been equipped with this update In a document released on Thursday, the NHTSA stated that the reviewed accident data is concerning: both the initially equipped and subsequently updated degradation detection systems **failed to effectively identify low visibility conditions and provide adequate warnings to drivers**. In the accidents reviewed by the NHTSA, the system failed to detect "common" road conditions that affect visibility, only alerting the driver just before a collision was about to occur. In these cases, the fully autonomous driving system "similarly lost or never detected" vehicles in the path ahead. This NHTSA investigation covers approximately **3.2 million** vehicles, including all models equipped with fully autonomous driving systems, such as specific versions of Model 3, Y, X, S, and the Cybertruck. The NHTSA stated that it will collect more information about the degradation detection systems and analyze six potentially related accidents ### 相關股票 - [Tesla (TSLA.US)](https://longbridge.com/zh-HK/quote/TSLA.US.md) - [GraniteShares 1.25 Long TSLA Daily ETF (TSL.US)](https://longbridge.com/zh-HK/quote/TSL.US.md) - [Direxion Daily TSLA Bull 2X Shares (TSLL.US)](https://longbridge.com/zh-HK/quote/TSLL.US.md) - [GraniteShares 2x Long TSLA Daily ETF (TSLR.US)](https://longbridge.com/zh-HK/quote/TSLR.US.md) - [Simplify Volt TSLA Revolution ETF (TESL.US)](https://longbridge.com/zh-HK/quote/TESL.US.md) - [T-Rex 2X Long Tesla Daily Target ETF (TSLT.US)](https://longbridge.com/zh-HK/quote/TSLT.US.md) - [Leverage Shares 2X Long TSLA Daily ETF (TSLG.US)](https://longbridge.com/zh-HK/quote/TSLG.US.md) - [GraniteShares 2x Short TSLA Daily ETF (TSDD.US)](https://longbridge.com/zh-HK/quote/TSDD.US.md) - [AXS TSLA Bear Daily ETF (TSLQ.US)](https://longbridge.com/zh-HK/quote/TSLQ.US.md) - [XI2CSOPTSLA-U (09366.HK)](https://longbridge.com/zh-HK/quote/09366.HK.md) - [XL2CSOPTSLA (07766.HK)](https://longbridge.com/zh-HK/quote/07766.HK.md) - [XI2CSOPTSLA (07366.HK)](https://longbridge.com/zh-HK/quote/07366.HK.md) ## 相關資訊與研究 - [Gordon Johnson Warns Tesla's Potential Recall Could Derail 'Robotaxi Story'](https://longbridge.com/zh-HK/news/279831936.md) - [Tesla Model Y L gets new entertainment feature](https://longbridge.com/zh-HK/news/279298211.md) - [Elon Musk Says SpaceX Will Beat 'Everyone Else Combined' In AI, Warns Non-AI Firms Risk Extinction](https://longbridge.com/zh-HK/news/279383442.md) - [Musk Speeds Up Tesla's Next-Gen AI Chip](https://longbridge.com/zh-HK/news/279798114.md) - [Key facts: Tesla's Terafab to Start Within Seven Days; Shanghai Delivers 59,000 Cars in February](https://longbridge.com/zh-HK/news/279132071.md)
