Tesla car, in autopilot mode, speeds up before crashing into parked fire engine

Two people were injured, including the owner of the car who has been charged with traffic offences.

A TESLA THAT crashed while in autopilot mode in Utah this month accelerated in the seconds before it smashed into a stopped firetruck, according to a police report obtained by the Associated Press.

Two people were injured.

Data from the Model S electric vehicle show it picked up speed for 3.5 seconds before crashing into the firetruck in suburban Salt Lake City. The driver manually hit the brakes a fraction of a second before impact.

Police suggested that the car was following another vehicle and dropped its speed to 89 kph to match the leading vehicle. They say the leading vehicle then likely changed lanes and the Tesla automatically sped up to its preset speed of 97 kph without noticing the stopped cars ahead.

The police report, which was obtained last week through an open records request, provides detail about the vehicle’s actions immediately before the 11 May crash and the driver’s familiarity with its system.

The driver of the vehicle, Heather Lommatzsch (29), told police she thought the vehicle’s automatic emergency braking system would detect traffic and stop before the car hit another vehicle.

She said she owned the car for two years and used the semi-autonomous autopilot feature on all kinds of roadways, including the Utah highway where she crashed, according to the report.

No warnings

Lommatzsch said the car did not provide any audio or visual warnings before the crash. A witness told police she did not see signs that the car illuminated its brake lights or swerved to avoid the truck ahead of it.

Lommatzsch did not return a voicemail message seeking comment.

Tesla referred to a prior comment that drivers are continually reminded to keep their hands on the wheel and maintain control of their vehicle at all times while using the autopilot system.

“Tesla has always been clear that autopilot doesn’t make the car impervious to all accidents,” it said.

Police say car data show Lommatzsch did not touch the steering wheel for 80 seconds before the crash. She told police she was looking at her phone and comparing different routes to her destination.

She broke her foot in the crash and this week was charged with a traffic misdemeanour. Online court records do not show a solicitor listed for her.

The driver of the firetruck told police he had injuries consistent with whiplash but did not go to a hospital.

Tesla’s autopilot system uses cameras, ultrasonic sensors and radar to sense the vehicle’s surrounding environment and perform basic functions automatically.

Among those functions is automatic emergency braking, which the company says on its website is designed “to detect objects that the car may impact and applies the brakes accordingly”.

Tesla says the system is not designed to avoid a collision and warns drivers not to rely on it entirely.

The US National Highway Traffic Safety Administration has said it is investigating the 11 May crash.

Tesla reached a settlement agreement in a federal lawsuit alleging that it sold autopilot features that weren’t available and made its vehicles dangerous, according to court records last week by the US District Court in San Jose.

Autopilot

Neither Tesla nor Seattle lawyer Steve Berman, who represented the plaintiffs, would provide comment.

But Tesla said previously that since rolling out its second generation of autopilot, it has continued to update software leading to major improvements.

The company has said that it agreed to compensate customers who purchased autopilot and had to wait longer than expected to get all of its features.

Tesla’s autopilot has been the subject of previous scrutiny following other crashes involving the vehicles.

In March, a driver was killed when a Model X with autopilot engaged hit a barrier while traveling at “freeway speed” in California. NHTSA and the National Transportation Safety Board are investigating that case.

This week, Tesla said autopilot was not engaged when a Model S veered off a road and plunged into a pond outside San Francisco, killing the driver.

Earlier in May, the NTSB opened a probe into an accident in which a Model S caught fire after crashing into a wall at a high speed in Florida. Two 18-year-olds were trapped and died in the blaze. The agency has said it does not expect autopilot to be a focus in that investigation.
