Tesla CEO Elon Musk has been overstating the capabilities of the company’s advanced driver assist system, the company’s director of Autopilot software told the California Department of Motor Vehicles. The comments came from a memo released by legal transparency group PlainSite, which obtained the documents from a public records request.It was the latest revelation about the widening gap between what Musk says publicly about Autopilot and what Autopilot can actually do. And it coincides with Tesla coming under increased scrutiny after a Tesla vehicle without anyone in the driver’s seat crashed in Texas, killing two men.
