A Texas man has been charged with manslaughter after his Tesla crashed into a home, killing a 76-year-old woman who was inside. The case is drawing fresh attention to the safety of driver-assist systems.
Michael David Butler, 44, was driving his 2025 Tesla Model 3 on June 19 when the vehicle left the road at a "high rate of speed," according to the Harris County Sheriff's Office. The car struck and entered the home of Martha Avila, who was inside at the time. She died as a result of the crash.
Driver Told Police He Was Using Full Self-Driving Mode
According to Reuters, Butler told law enforcement that he was operating his Model 3 in Full Self-Driving (FSD) mode when the crash happened. The claim has raised questions about the reliability of Tesla's semiautonomous driving technology.
The Wall Street Journal reported that Butler made this claim to law-enforcement officials shortly after the incident. The National Highway Traffic Safety Administration (NHTSA) is also investigating the crash, as confirmed by the original story.
Manslaughter Charge Filed in Harris County
Butler has been charged with manslaughter in connection with Avila's death. The charge reflects the serious legal consequences that can follow when a driver is believed to have been relying on automated driving features in a fatal crash.
The Harris County Sheriff's Office said the vehicle was traveling at a high rate of speed before it left the roadway and struck the home. The exact speed has not been publicly confirmed.

Our Take: This Case Highlights the Limits of Driver-Assist Technology
This is not the first time a Tesla crash has involved claims of automated driving, but the manslaughter charge marks a significant legal step. In our view, it sends a clear message: drivers cannot simply hand over control to a machine and avoid responsibility for what happens next.
Full Self-Driving and Autopilot are advanced driver-assist systems, not fully autonomous technology. Tesla itself warns drivers to remain attentive and keep their hands on the wheel. But in practice, many drivers treat these systems as if they can drive themselves. This case shows the tragic consequences of that misunderstanding.
The NHTSA investigation will likely focus on whether the system was actually engaged at the time of the crash and whether it performed as intended. But regardless of the technical findings, the legal system is holding the driver accountable. That is the right approach — until the technology is truly proven safe, the human behind the wheel must remain responsible.
