A Model S owner has told police that Autopilot was engaged when she crashed into a parked firetruck in Utah last week.

The 28-year-old said that she was using her phone prior to the collision while the semi-autonomous driving features was enabled. The crash caused significant damage to the high-performance electric sedan and could again raise questions about Tesla’s self-driving systems – or, more accurately, owner’s perception of how it actually works.

According to the police, the Model S slammed into the firetruck at 60 mph (96 km/h) and the driver suffered a broken right ankle. Jalopnik asserts that witnesses of the crash didn’t see the Model S brake before the impact.

Autopilot crashes: Is it the tech or the driver?

In a statement, the electric automaker said it hasn’t received information about the crash: “Tesla has not yet received any data from the car and thus does not know the facts of what occurred, including whether Autopilot was engaged.”

Despite this, CEO Elon Musk hit out at coverage in the immediate aftermath of the crash, asserting that a crash of this sort would usually result in “severe injury or death.”

“It’s super messed up that a Tesla crash resulting in a broken ankle is front page news and the ~40,000 people who died in US auto accidents alone in past year get almost no coverage.”

Tesla began to crack down on the misuse of Autopilot when the first accidents involving the technology occurred. It has repeatedly insisted that, despite Autopilot’s name, the technology is simply a driver-assistance system.
