Tesla’s FSD Under NHTSA Probe Over Deadly Crashes Involving Sun Glare and Fog Risks

The National Highway Traffic Safety Administration has launched a new investigation into Tesla’s Full Self-Driving (FSD) system after multiple crashes were reported in reduced visibility conditions such as fog, sun glare, and airborne dust, including at least one fatal accident.

Tesla’s Vision-Only Approach Under Scrutiny

Regarding its vision-only strategy for autonomous driving, Tesla has maintained to face substantial skepticism.

Now, the NHTSA has begun a new inquiry into the purportedly impaired capability of Tesla's custom autonomy solution to traverse low-visibility situations, just as the electric vehicle behemoth is preparing to release an unsupervised FSD as early as next year.

NHTSA Investigates Low-Visibility Crashes

Specifically, the National Highway Traffic Safety Administration (NHTSA) has initiated an initial inquiry into multiple traffic accidents that happened in low-visibility situations when Tesla's FSD was turned on. Tragically, one of the four accidents under scrutiny resulted in death. Notated by the agency:

"In these crashes, the reduced roadway visibility arose from conditions such as sun glare, fog, or airborne dust."

Delays Could Impact Tesla's 2026 Cybercab Launch

Although this inquiry is still in its early stages, a negative outcome might significantly delay Tesla's plans to release its FSD with unsupervised capability next year, which would mean a postponement of the fully autonomous Cybercab debut in 2026.

As reported by WCCFTECH, it should be noted that Elon Musk had previously stated during the October 10th Cybercab reveal event that the "fully autonomous" unsupervised FSD for Models S, 3, X, and Y will begin to be distributed in 2019 in the states of Texas and California, and that the Cybercab will formally debut "before 2027."

FSD Still Lags Behind Waymo’s Disengagement Rates

Nevertheless, there are those who continue to doubt Tesla's intentions about autonomy, especially in light of the data that is currently available from the California DMV, which shows that Waymo averages a disengagement every 17,311 miles—far more than what the FSD is capable of.

LiDAR May Become a Necessity for Tesla

Although, if the NHTSA were to issue a negative verdict, Tesla might be compelled to add LiDAR sensors to its vision-only autonomous driving system.

However, with the unsupervised FSD being trained on a vision-only neural network, this conclusion will be quite costly and would significantly delay Tesla's autonomy-related objectives.
