Was on the highway yesterday staring straight into the sun on the horizon, and FSD started swerving like a mildly inebriated person! Ed Ludlow / @edludlow : FSD (Supervised) v12.5.4.1 30 miles from home to work. No interventions. GG bridge and Van Ness/Lombard Dog leg no problem. Boring on freeway. Illogical lane changes but MLCFCD wasn't selected. There was however a very curious and slightly concerning occurrence. At the moment I @transportworker : We welcome a full investigation but why the hell is this unproven and dangerous technology being allowed on our roads in the first place? @Tesla knows this tech doesn't work and is killing people, but they sell it anyway. https://www.cnbc.com/... @reuters : US regulators are opening an investigation into 2.4 million Tesla vehicles after reports of crashes where Full Self-Driving software was engaged https://www.reuters.com/... [video] Nat Friedman / @natfriedman : Tried the latest Tesla FSD today in rush hour traffic and I am very impressed. It handled congested high-speed merges better than I would have handled them. No mistakes the whole drive home, very smooth, and less overcautious-feeling than before. @factschaser : Five months before NHTSA stepped in, I noted in May 👇 that Tesla FSD failing due to sun glare is not a good omen for robotaxis — why Musk could not demo robotaxis in a real city and leaned on Hollywood's wizards to help him pimp fake robotaxis in a fake movie studio city 😂 @wholemarsblog : NHTSA has opened an investigation into 4 crashes involving Tesla FSD Beta or FSD Supervised where sun glare, fog, or airborne dust reduced roadway visibility. NHTSA preliminary evaluation will assess how FSD detects and responds to reduced roadway visibility [image] @unusual_whales : Tesla, $TSLA, Full Self-Driving System is facing a probe from the National Highway Traffic Safety Administration after a pedestrian death. It will determine if FSD has the ability to detect & appropriately respond to fog and other situations where roadway visibility is reduced [image] @227thomas : Tesla can't handle things “like sun glare, fog, or airborne dust”. Or snow. Or Rain. Almost as if there is a reason every other company - that, unlike Tesla, already has(!) full autonomy on the road - uses lidar and radar. $tslaq $tsla https://www.reuters.com/...

Dean Baker / @deanbaker13 : I imagine Trump will nix this investigation of Tesla self-driving car crashes if he gets in https://www.washingtonpost.com/ ... I'm sure people will be happy to have their kids plowed down by Elon Musk's toys, it's MAGA! Andreas West / @a4xrbj1 : This beta software with insufficient sensors for low visibility conditions like fog shouldn't be allowed on the roads unless driven by Tesla employees for testing purposes! $TSLAQ $TSLA https://www.reuters.com/...

Context & Ripple Effects
Tesla's driver-assistance safety record was already under scrutiny after leaked customer FSD complaint data documented thousands of reported issues across earlier model years. This inquiry narrows the question to how the system handles visibility degradation, a test case for whether automated-driving claims can be meaningfully audited in real-world edge conditions.
The issue did not remain isolated in the coverage: a later NHTSA inquiry into reported traffic-safety violations indicates continued regulatory attention to FSD-enabled vehicles. That makes the visibility investigation consequential beyond the individual crash reports.
First-order effects
- NHTSA will assess Tesla FSD's ability to detect and respond when glare, fog, or airborne dust reduce visibility across the affected vehicle population.
- Tesla faces a federal safety review centered on its software behavior and incident reporting in the four cited crashes, including the fatality.
Second-order effects
- The probe increases pressure on Tesla to demonstrate how FSD identifies degraded sensing conditions and when it should limit or alter its behavior, raising the importance of complaint and incident records in regulatory review.
- Other automated-driving developers face a clearer signal that performance claims will be judged against difficult operating conditions, not only routine driving scenarios.
Third-order effects
- If repeated probes continue to focus on software-driven vehicle behavior, vehicle safety oversight may shift further toward ongoing software auditability rather than one-time vehicle certification.
- The central competitive question for driver-assistance systems may become whether companies can substantiate safe operating limits and provide regulators usable evidence when systems encounter edge cases.
The trend: Automated-driving oversight is moving toward evidence-based scrutiny of software performance in specific real-world failure conditions.
