A Texas driver was charged with manslaughter Thursday after crashing a Tesla into a home in Katy, killing a 71-year-old woman, as investigators found the driver overrode the vehicle's driver-assistance system before the collision.
"The driver intentionally disabled safety features before the crash," Harris County Sheriff Ed Gonzalez said in a statement. "This was not a failure of the technology — it was a deliberate override."
The Tesla left the roadway and struck a residence in the Katy area west of Houston, killing the grandmother who was inside the home at the time. The driver faces a second-degree felony charge of manslaughter, which carries a potential sentence of 2 to 20 years in prison, according to the Harris County District Attorney's Office. Investigators determined the driver acted to override the car's automated driving assistance system, though the specific mechanism of the override has not yet been disclosed.
The case adds to a growing body of legal scrutiny around Tesla's driver-assist features, which the National Highway Traffic Safety Administration has investigated in more than 35 crashes involving the technology since 2021. While NHTSA has opened multiple probes into Tesla's Autopilot and Full Self-Driving systems, criminal charges against individual drivers remain rare. A conviction in this case could set a precedent for holding drivers — rather than automakers — criminally liable for misuse of semi-autonomous systems, potentially reshaping liability frameworks across the industry.
Tesla's approach to driver-assist technology has drawn increasing attention from regulators. The company's systems require active driver supervision and do not make the vehicle fully autonomous, according to Tesla's owner manuals. However, critics have argued that the naming of features such as "Full Self-Driving" may encourage drivers to treat the systems as more capable than they are. The National Transportation Safety Board has previously recommended that Tesla incorporate stronger driver-monitoring safeguards, recommendations the company has not fully adopted.
The incident comes as Tesla faces multiple federal investigations into the safety of its driver-assistance technology. The Department of Justice has also sought information from the company related to its marketing claims about Autopilot and FSD, according to public filings. Tesla shares fell 2.3% in after-hours trading following the news, though the broader impact on the company's valuation will depend on whether the case triggers additional regulatory action or a formal recall.
