Most of the videos follow the same formula: Cell phone footage shot on a highway shows a Tesla driver reclining in their seat, hands not on the wheel. As the person filming the video passes them, it becomes clear that the Tesla driver isn't even awake: "I think this guy is, like, passed out in his Tesla."

Tesla's semiautonomous Autopilot feature has led to an alarming new genre of viral videos in 2019: Drivers sleeping at the wheel while their Tesla barrels down the highway.

The trend has been heavily documented in recent months - in The New York Times Magazine, Peter Baker described the ominous sensation of watching a "human lulled to sleep inside a hunk of metal and glass, hurtling down a highway under the control of proprietary algorithms beamed on board from Palo Alto."

Tesla has insisted that the feature makes drivers safer, and a Bloomberg survey last month found that over 90% of Model 3 owners agree. The company also says drivers must keep their hands on the wheel and pay attention to the road while driving on Autopilot - however, Tesla CEO Elon Musk has repeatedly used Autopilot with his hands off the wheel during demonstrations.

Here are all the times Tesla drivers were caught apparently sleeping at the wheel throughout 2019.
