Tesla Autopilot function update follows accidents and court case

Authorities and users question autonomous driving feature after crashes in China and US

US electric carmaker Tesla Motors Inc, which was widely praised for its Autopilot, has been under fire for the same system since a Model S sedan crashed into a semi trailer that was crossing a Florida highway in May and killed the driver.

The fire has now been fueled further in China, as a court in Beijing's Chaoyang district has accepted a lawsuit fi led in July against Tesla by the family of a 23-year-old driver, Gao Yaning, who died in January, reported the China Central Television. It was the world's first fatal Tesla accident known so far.
