NTSB says driver overrode Tesla system before deadly Katy crash
The NTSB says a Katy Tesla was in supervised Full Self-Driving when the driver floored the accelerator and hit a home at more than 70 mph, killing Martha Avila.
The National Transportation Safety Board says a Tesla driver in Katy overrode Full Self-Driving before a June crash that killed 76-year-old Martha Ávila in her family home. The preliminary report adds a crucial detail for Harris County drivers weighing assisted-driving technology on local streets: the car was moving faster than 70 mph in a 30 mph neighborhood just before impact.
The federal report, released July 15, says the crash happened about 8:03 p.m. June 19 on Rose Hollow Lane in Katy, when a 2025 Tesla Model 3 with a single 44-year-old driver left the roadway, partially entered a driveway and crashed into a residence. Investigators say the driver had engaged Tesla Full Self-Driving, labeled Supervised, and then manually overrode it by pressing the accelerator to 100%. Security camera footage showed the car continuing straight through the intersection instead of turning right at Blooming Park Lane, where Rose Hollow Lane ends.
Conditions were not a factor in the same way speed was. The report says the weather was clear, the roadway was dry and daylight conditions were present. NTSB says the vehicle struck the residence at more than 70 mph, far above the posted limit on Rose Hollow Lane.
Ávila was the fatal victim inside the home. The report says one occupant in the residence was killed and the driver sustained minor injuries. Michael Butler has been charged with manslaughter, and court records and news reports say his bond was set at $150,000. Separate court filings say Butler was working as a DoorDash driver at the time of the crash.
The crash has already triggered a wrongful death lawsuit in Harris County from Jennifer Barbour and Justin Barbour, Ávila’s daughter and son-in-law. Their filing says Justin Barbour was injured and the family was displaced from the home after the Tesla crashed through the front wall. The Harris County Sheriff’s Office and Tesla are participating in the NTSB investigation, and the National Highway Traffic Safety Administration has opened a special crash investigation.
A law professor cited in local television coverage said Tesla Full Self-Driving remains a Level 2 system, meaning the human driver is still responsible for watching the road and taking over. For Harris County motorists, the lesson is blunt: driver-assistance systems may help with control, but they do not replace judgment, especially on short neighborhood streets where one wrong input can turn a routine turn into a deadly impact.
