US Auto Safety Regulator Investigates Fatal Tesla Crash into Texas Home

A fatal crash involving a Tesla that drove into a home is now being investigated by the US auto safety regulator.

The National Highway Traffic Safety Administration (NHTSA) opened a formal inquiry on Monday into an accident that occurred on 19 June in Texas, in which a man driving a Tesla sped off the road.

A woman who was in the house was severely injured and died as a result, according to a report of the incident from local police.

The driver was not intoxicated, police said, but claimed his Tesla was operating at the time with "an automated driving assistance system."

A representative of Tesla, which is owned by trillionaire Elon Musk, did not respond to a request for comment on the crash or the investigation.

The fatal crash occurred around 8pm local time on Friday. The driver of a Tesla Model 3 "failed to drive in a single lane, left the roadway, and struck the residence," the police report stated.

In a statement given to local media the night of the crash, Sgt Alex Turman of the Harris County Sheriff's Office said the vehicle "failed to turn right at an intersection and, at a high rate of speed, crashed directly into a house."

The 76 year-old woman who was inside the home was struck and was taken to a hospital, but she died of her injuries, the officer added.

The driver was also taken to hospital and was cooperating with the investigation into the crash, police said.

The police gave no indication of what caused the car to speed off the road and into the woman's home, but Sgt. Turman did say that one line of investigation by police was the driver's claim that he was driving at the time using an automated driving system.

"We're still evaluating what caused the car to fail to control its speed just before this crash," he said.

A special crash investigation from the NHTSA is the most "in-depth and detailed" form of inquiry the agency does, according to its website. It is separate from the local police investigation.

Such investigations often cover emerging technology in vehicles in order for the agency to gather data on crashes that can then be used to improve safety performance in autos more widely.

While the investigation is not intended to immediately penalise a car manufacturer, it can lead to safety recalls or other actions.

The technology has been criticised as misleading in its abilities, and earlier this year the NHTSA expanded an investigation into it over its potentially poor performance in inclement weather.

Last week, Democratic Senators Edward Markey and Richard Blumenthal sent a letter to the NHTSA demanding that the agency investigate Tesla's full self-driving (FSD) technology for its safety risks.

"Tesla has claimed its FSD technology is safer than human driving, but the claims are based on misleading data analysis, such as comparing unlike crash outcomes, comparing new vehicles to the entire US vehicle fleet, and relying on incomplete crash data", the senators wrote.
