Tesla owners have been reminded to keep their eyes on the road after videos of drivers wearing Apple's virtual reality headset have gone viral.
US Secretary for Transport Pete Buttigieg posted on X (formerly Twitter) to say that all current vehicles require the driver to be engaged "at all times".
However, one driver admitted his video was a prank.
Tesla and Apple have been contacted for comment.
Videos posted online show people in the drivers seats of cars which have an autonomous mode, while wearing the Apple headset over their eyes.
