A Houston resident has filed a lawsuit against Tesla after her Cybertruck allegedly attempted to drive off an overpass while using Elon Musk's 'Full self driving' feature, resulting in serious injuries. The incident occurred in August 2025 on the 69 Eastex Freeway in North Houston, where Justine Saint Amour was driving her Cybertruck with Tesla's full self-driving mode engaged. According to the lawsuit, the vehicle suddenly attempted to drive straight ahead toward a concrete barrier and a drop to the freeway below, despite the expected right curve of the road.

Why it matters

This case highlights ongoing concerns about the safety and capabilities of Tesla's 'Full Self-Driving' feature, which has faced scrutiny from regulators over misleading marketing claims. It also raises questions about Tesla's reliance on camera-only technology versus more advanced autonomous driving sensors like lidar used by competitors.

The details

According to the lawsuit, Saint Amour attempted to disengage the self-driving feature and correct the vehicle's course, but had insufficient time to react. The Cybertruck crashed into the concrete barrier, causing substantial injuries including two herniated discs in her lower back, one herniated disc in her neck, sprained tendons in her wrist, and neuropathy in her right hand. Dashcam footage shows the Cybertruck driving directly into the sidewall after attempting to navigate a fork in the road.

  • The incident occurred in August 2025 on the 69 Eastex Freeway in North Houston.
  • Saint Amour purchased her Cybertruck at a used car dealership in Florida in February 2025.

What they’re saying

“Tesla's decisions made Justine's accident inevitable. This company wants drivers to believe and trust their life on a lie: that the vehicle can self-drive and that it can do so safely. It can't, and it doesn't.”

The judge in the case will decide on whether to allow the lawsuit to proceed as a class action against Tesla.
