Under Scrutiny: Feds Intensify Probe Into Tesla’s Vision-Only ADAS
The NHTSA has escalated its investigation into Tesla’s 'Full Self-Driving' (Supervised) software. The probe focuses on system performance during low-visibility conditions, following reports of continued technical struggles.
Federal regulators are turning up the heat on Tesla’s ADAS ambitions. The National Highway Traffic Safety Administration (NHTSA) has officially upgraded its investigation into Tesla’s "Full Self-Driving" (Supervised) software after identifying recurring issues where the vision-only system struggles in low-visibility environments, such as heavy rain, fog, or sun glare.
Tesla’s decision to rely exclusively on cameras—eschewing LiDAR and radar—has been a point of contention among safety experts for years. This upgraded probe suggests that the "pure vision" approach may face a ceiling when it comes to handling the "long tail" of edge cases required for Level 3 or Level 4 autonomy. The investigation will scrutinize how the software processes environmental data and whether it provides sufficient warnings to human supervisors.
For the ADAS industry, this serves as a cautionary tale regarding the balance between aggressive feature rollout and rigorous safety validation. As regulators demand more transparency, the results of this probe could set new standards for how all semi-autonomous systems are tested and marketed to the public.
