Manslaughter Charges Filed Following Fatal Tesla FSD Crash

A fatal crash involving Tesla's driver-assistance technology has resulted in manslaughter charges against a Texas man after his vehicle slammed into a home near Houston, killing a 76-year-old woman inside, according to the Wall Street Journal.

Prosecutors say 44-year-old Michael David Butler told first responders he had been using Tesla's Full Self-Driving (Supervised) feature while making a DoorDash delivery on June 19. Butler claimed he changed the music on the touchscreen before losing consciousness. Authorities said he was the only person in the car and that toxicology tests found no evidence of alcohol or drugs.

However, data recovered from the vehicle paints a different picture. Investigators said Butler repeatedly overrode the FSD system by pressing the accelerator, with the Tesla reportedly reaching speeds as high as 73 mph in a residential neighborhood. Officials also said there was no braking in the final moments before the vehicle crashed into the home. Investigators further uncovered Google searches indicating Butler had been frustrated that the software was not driving aggressively enough.

The WSJ reported that Tesla has pushed back on Butler's version of events, stating that vehicle data shows the accelerator was held down by the driver both before and after the collision. The crash is now also under investigation by the National Highway Traffic Safety Administration as part of its ongoing scrutiny of advanced driver-assistance systems.

The crash is likely to intensify the long-running debate surrounding Tesla's Full Self-Driving technology. Although the software is marketed as capable of handling steering, braking, and acceleration in many driving situations, Tesla has consistently maintained that the system requires a fully attentive driver who is prepared to take control at any moment. Despite its name, Full Self-Driving is not an autonomous driving system.

Critics have argued for years that the branding has created confusion among some drivers, leading them to place more trust in the technology than Tesla's own warnings recommend. Regulators have repeatedly examined whether drivers are using the system as intended, while safety advocates have questioned whether the software encourages a false sense of security behind the wheel.

The National Highway Traffic Safety Administration has opened numerous investigations into crashes involving Tesla's advanced driver-assistance features over the past several years, including several fatal incidents. Those investigations have fueled ongoing scrutiny of the company's autonomous driving ambitions as Tesla continues to make artificial intelligence and self-driving technology central to its long-term strategy.
