A popular electric vehicle made by the Chinese consumer electronics giant Xiaomi crashed into a concrete guardrail while deploying its autonomous driving feature. Three people died.

Chinese EV maker Xiaomi said it would cooperate with a police investigation into a fatal crash involving one of its cars which had been in autonomous mode just before the accident. Xiaomi founder Lei Jun said in a social media post late Tuesday that he was "heavy-hearted" and that his company would "continue to cooperate with the police investigation".

Xiaomi Corp. confirmed that one of its SU7 electric vehicles was involved in an accident on an expressway in China. Local media reported that three people died in the incident that’s likely to spark scrutiny over the smart driving software deployed in many of today’s cars.
