A Utah woman who in May 2018 crashed her Tesla Model S into a fire engine while having the Autopilot assist mode engaged has now sued the company in state court, claiming negligence, among other allegations. The civil complaint was first posted on Wednesday by Matt Drange of The Information.

Attorneys for Heather Lommatzsch, the plaintiff, wrote on Tuesday that she "understood" that the car’s "safety features would ensure the vehicle would stop on its own in the event of an obstacle being present in the path of the Tesla Model S."

In the aftermath of the May 2018 accident, police in South Jordan, Utah, said in a statement that the woman told them that she "was looking at her phone prior to the collision" and that she reportedly "did not brake or take any action to avoid the collision."

As a result, the South Jordan Police Department cited her for "failure to keep proper lookout."

According to police at the time, Lommatzsch suffered a broken right foot as a result of the accident, but the Wednesday lawsuit claimed "serious physical injuries" and added that she has lost "the pleasures and enjoyment of life and physical impairment."

While Tesla did not immediately respond to Ars’ request for comment late Wednesday evening, spokesman Dave Arnold told the Associated Press in a statement earlier in the day that the company "has always been clear that Autopilot doesn’t make the car impervious to all accidents."

He continued, noting that the responsibility rests with drivers to "keep their hands on the wheel and maintain control of the vehicle at all times."

As Ars pointed out in May 2018, just a week before Lommatzsch’s crash, there is little evidence to support the company’s claim that Autopilot’s first iteration "was found by the US government to reduce crash rates by as much as 40 percent."
