A man has been caught on camera sleeping behind the wheel of his Tesla Model X while driving the car on Autopilot.
The man was filmed by someone in a nearby car, who was shocked to see him snoozing on a Las Vegas road.
The video, posted on Jalopnik, reveals that the man's hands are not visible on the wheel. He is also resting comfortably on the seat's head rest.
It remains unclear if the man was eventually pulled over.
Tesla's website states that every vehicle it produces has the 'hardware needed for full self-driving capability', offering an 'Enhanced Autopilot' package for $5,000.
The package promises the enhanced autopilot will 'match speed to traffic conditions, keep within a lane, automatically change lanes without requiring driver input, transition from one freeway to another, and exit the freeway when your destination is near'.
It claims the system can even 'self-park when near a parking spot and be summoned to and from your garage'.
Tesla's 'Full Self-Driving' package includes the capacity for the car to drive itself. That costs an extra $3,000.
But these pricey features don't guarantee safety. There have been a number of crashes that occurred with a Telsa car that had Autopilot turned on.
In 2016 an Ohio man was killed after his Tesla hit a semi-truck while Autopilot was engaged.
The National Transportation Safety Board ruled that Tesla's 'lack of sufficient system controls' was partially to blame.
Tesla has since placed restrictions on how long a driver can keep their hands off the steering wheel before a warning beep sounds.
If they remain unresponsive, the system is equipped to stop and turn the car's hazard lights on.
But the problems haven't stopped. Just last month California Highway Patrol troopers spotted a man sleeping in the driver's seat of his Tesla Model S. He was going 70mph.
The officers had to pull in front of the car and start slowing down so that the car would eventually slow itself down as well, according to Wired.
Videos have also been posted on YouTube teaching Tesla drivers how to bypass the system by wedging an orange or water bottle in the steering wheel.
