Seeing is believing—until the fog rolls in
Tesla: Failure of the FSD's degradation detection system [pdf]
Feds probe Tesla’s camera‑only FSD after crashes; commenters scream “yikes” and “use lidar”
TLDR: U.S. regulators are investigating Tesla’s camera‑only driver assist for failing to spot poor visibility and warn drivers before nine crashes, including one death. Commenters pile on: many slam the “vision only” strategy and demand lidar, while others ask how drivers can trust a system that can’t admit it’s struggling.
Buckle up: U.S. safety investigators just opened a probe into Tesla’s camera‑only Full Self‑Driving after nine crashes in bad visibility, including one fatal. The government says the system often didn’t recognize its own “I can’t see” moments—think glare, fog, dust—or warn drivers until right before impact. Tesla started working on a software fix on June 28, 2024, but no one knows which cars got it. Making things spicier, regulators hint crash counts may be underreported due to Tesla’s data labeling limits.
The comments section? A tire fire. The top theme is outrage at the “cameras only” strategy after ditching radar: “This is cost‑cutting cosplay,” one summed up, with another invoking Wile E. Coyote and cartoon anvils. A sarcastic zinger went viral: the car couldn’t reliably say “there’s a car there” in fog. Others took the sober route: if the system can’t flag low confidence, how is a human supposed to know when to grab the wheel? One user called it “pretty egregious… overall, yikes.”
The drama split the room into two camps: vision‑only true believers (few in this thread) versus “add lidar or go home”. Some say a premium car should ship every sensor under the sun; others argue software should handle it—but admit this is a bad look. Everyone’s watching to see if this becomes a recall or a rushed update, while the memes keep flying faster than a Cybertruck in a sandstorm.
Key Points
- •ODI opened Engineering Analysis EA26002 into Tesla’s FSD degradation detection under reduced visibility conditions.
- •About 3,203,754 FSD-equipped Tesla vehicles (Model S/X/3/Y and Cybertruck in specified years) are included.
- •ODI cites nine crashes/fires, two injury incidents (one injury), and one fatality incident in its summary.
- •Tesla adopted the camera-only Tesla Vision in mid-2021 and deployed a degradation detection system via software update.
- •Tesla began developing an update to that system on June 28, 2024; deployment details are unknown, and data limitations may have led to under-reporting.
