Gao Yaning, the 23-year-old driver, died in January after his Tesla Model S slammed into a road-sweeping vehicle on a highway in the northern province of Hebei. His father Gao Jubin filed the case against the company in June, lawyer Cui Qiuna told AFP.
The family believed the son was driving in Tesla's Autopilot mode and accused the firm of overstating the function's capabilities, she said.
During the trial's opening session in Beijing yesterday, Gao applied for an investigation into whether the autopilot was activated when the accident occurred, she added.
"Tesla has been contacting Mr. Gao for a talk over reconciliation conditions but has yet to put forward a concrete solution," she said.
