FRANKFURT -- German Transport Minister Alexander Dobrindt has asked Tesla to stop advertising its vehicles as having an Autopilot function because this might suggest drivers' attention is not needed.
Germany's Federal Motor Transport Authority (KBA) had written to Tesla to make the request, a transport ministry spokeswoman said on Sunday, confirming a report in the Bild am Sonntag newspaper.
"It can be confirmed that a letter to Tesla exists with the request to no longer use the misleading term Autopilot for the driver assistance system of the car," she said in a written response to a Reuters' query.
A Tesla spokeswoman said the Autopilot term, describing a system operating in conjunction with a human driver, had been used in aerospace for decades. The company had always made it clear to customers that the assistance system required drivers to pay attention at all times.
"Just as in an airplane, when used properly, Autopilot reduces driver workload and provides an added layer of safety when compared to purely manual driving," she said.
On Friday the KBA -- which reports to Dobrindt -- wrote to owners of Tesla cars, warning them that their vehicles could not be operated without their constant attention and that under traffic regulations they must remain alert.
According to the Bild am Sonntag report, the KBA letter to Tesla said: "In order to prevent misunderstanding and incorrect customers' expectations, we demand that the misleading term Autopilot is no longer used in advertising the system."
Tesla's Autopilot has been the focus of intense scrutiny since a Tesla Model S driver was killed while using the technology in a collision with a truck in Florida in May.
