76-Year-Old Grandmother Killed After Tesla On Autopilot Crashes Into Her Living Room
The 44-year-old driver of a Tesla Model 3 that crashed into a house in Katy, Texas, killing a 76-year-old grandmother who was standing in the living room, has told investigators that his vehicle had Autopilot engaged when the crash occurred. Images shared by the Harris County Precinct 5 Constable's Office show the aftermath of the devastating crash, and a video obtained by ABC News (embedded below) shows the vehicle traveling at an alarmingly high rate of speed, blowing through an intersection in the residential neighborhood before impact with the brick house. The crash occurred around 8 PM on Friday, and the driver, Michael Butler, reportedly showed no signs of intoxication and has been cooperating with investigators. He was taken to hospital by ambulance, while the victim, Marth Avila Mantilla, was airlifted to Memorial Hermann Hospital, but was later pronounced dead.
Tesla Autopilot and FSD Raise Concerns About Safety
It's unclear whether Butler was using Autopilot or Tesla's more capable "Full Self-Driving (Supervised)" system, but neither is a truly autonomous self-driving technology, and both require the driver to be attentive. Regardless, this crash raises questions about how safe Tesla's semi-autonomous driving technology is and how drivers are using it. If the vehicle was being driven semi-autonomously, why did it have the ability to drive so fast in a residential neighborhood? Autopilot or FSD operation on a freeway would justify such rapid driving, but this was a road where neighbors' children were celebrating a birthday and where a grandmother was minding her own business in the comfort of her home. Why did the Tesla blow right through a stop sign? And if it was malfunctioning, why did the driver not do anything to slow the car? If he did, why did the vehicle not respond? Asked about whether the Tesla was using a semi-autonomous driving system, as the driver claimed, Harris County Sheriff's Office Sergeant Alex Turman said, "We're digging into that. That's a line of investigation for sure." Tesla did not respond to ABC's request for comment, but it has continually claimed that its technologies make cars safer.
Tesla Driving Aids Always Attract Controversy
When a system is tasked with keeping road users safe, it's concerning to learn that it can be easily fooled by props, allowing users to get away with treating the tech as a true self-driving system. California regulators have pressured Tesla into dropping Autopilot in the state because of how misleading the name is, and the company has been found liable in previous fatal crashes involving the system. This latest incident in Texas highlights just how important it is for Tesla to be held accountable and for drivers to understand how to use the company's tech safely, but progress is slow, and as several competing companies seek to take control of the self-driving sector with their own technologies, one can't help but wonder how many corners may be cut and how many lives may be put at risk in the process.
