NHTSA Probes comma.ai Over 30,000 Cars, 5 Crashes

KEY FACTS

  • A Reddit user connected an AMD RX 9060 graphics card to a 2021 Toyota Alphard to run comma.ai's open-source driver assistance system.
  • comma.ai was founded by hacker George Hotz, and its openpilot software is compatible with over a hundred vehicle models.
  • The device connects via a plug-and-play harness to the rearview mirror and draws power from the OBD port, requiring no replacement of original vehicle parts.
  • Last month, NHTSA opened an investigation into three comma.ai hardware devices and the openpilot software, covering approximately 30,000 vehicles.
  • Public records document five high-speed collisions, resulting in three deaths and eleven injuries.

PHYSIX OBSERVATION

Aftermarket driver assistance uses a single graphics card to boost compute a hundredfold, but open-source tinkering renders driver monitoring all but useless, and accident liability is nearly impossible to assign. The NHTSA investigation exposes not just technical bottlenecks but the endgame of the 'hit the road first, fix it later' model. For users, the allure of upgrading an old car comes with dual legal and safety red lines, and in China it directly crosses into the forbidden zone of illegal modification.
