Tesla in fatal California crash was on Autopilot

Electric carmaker Tesla says a vehicle involved in a fatal crash in California was in Autopilot mode, raising further questions about the safety of self-driving technology. One of the company's Model X cars crashed into a roadside barrier and caught fire on 23 March. Tesla says the 38-year-old driver, who died shortly afterwards, had activated Autopilot moments before the accident. But they did not say whether the system had detected the concrete barrier. "The driver had received several visual and one audible hands-on warning earlier in the drive," a statement on the company's website said.
