Though it could be faked, and no one has tracked down the driver to confirm, a video surfaced on the site Electrek (via Reddit, of course) appearing to show a man asleep behind the wheel of a Tesla Model S in Autopilot mode.

Tesla released the Autopilot software last fall, and as Tech Insider says, while it is "a pretty incredible system" that would allow a person to kind of zone out while in mind-numbing traffic, "Tesla and its CEO Elon Musk have repeatedly told drivers not to sleep at the wheel with Autopilot on, and that it's important for drivers to have their hands on the wheel in case anything should happen."

And after being shown the video, Tesla Motors issued the following statement:

Tesla Autopilot is designed to provide a hands-on experience to give drivers more confidence behind the wheel, increase their safety on the road, and make highway driving more enjoyable. Autopilot is by far the most advanced such system on the road, but it does not turn a Tesla into an autonomous vehicle and does not allow the driver to abdicate responsibility. Since the release of Autopilot, we’ve continuously educated customers on the use of the feature, reminding them that they’re responsible for remaining alert and present when using Autopilot and must be prepared to take control at all times.

Meanwhile, there have been some PR wins for Tesla since the Autopilot software came out, like this video from October from a Seattle Uber driver whose Tesla saved him from a crash. But then there have been other, scarier stories of Model S's going rogue, like this one out of Utah in which a man claims his car drove him into a parked tractor-trailer, or the video below in which a man's autopilot steered him off onto a freeway exit instead of staying on the freeway.

So, yeah, Tesla owners, for everyone's safety, let's remember that the future isn't quite here yet, and this shit is not foolproof. Or drunk-proof. Stay awake, for god's sake.
