Texas: A 76-year-old woman was killed after a Tesla Model 3 allegedly using an automated driving assistance system crashed into her home in Texas, prompting an ongoing investigation into the fatal incident.

The victim, identified as Martha Avila, was inside her home in the Katy area of western Harris County when the Tesla Model 3 left the roadway and slammed into the residence. She was airlifted to a hospital but later succumbed to her injuries.

Driver injured in crash

The driver, identified as Michael Butler, was also injured and was transported to hospital by ambulance. Investigators said there were no immediate signs of intoxication and that Butler was cooperating with authorities as the investigation continues.

According to the Harris County Sheriff's Office, the vehicle was reportedly operating with an automated driving assistance system at the time of the crash.

Investigators said Butler allegedly failed to remain within a single lane before the vehicle veered off the road and crashed through the brick home at a high speed.

The impact destroyed part of the residence and struck Avila while she was inside the front room of the house.

Family struggles to process tragedy

Avila's daughter, Jennifer Barbour, said she was in the backyard when she heard what sounded like an explosion. After checking on her husband and children, she realised her mother had been hit by the vehicle.

Speaking to local media, Barbour described her mother as healthy and active and said the family was devastated by the sudden loss.

Authorities have not yet determined the exact cause of the crash and are continuing to investigate the circumstances surrounding the incident, including the role played by the vehicle's automated driving assistance system.

The case is likely to add to ongoing scrutiny of advanced driver-assistance technologies as regulators and investigators continue to examine their safety and limitations in real-world driving conditions.
