Video showing a Tesla Model S is driving on a road without someone in the driver's seat circulating on social media Monday night .
The luxury electric car appeared to operate on Autopilot, Tesla's semi-autonomous vehicle technology, which allows the vehicles to be equipped with the function of steering, accelerating, braking and changing lanes with driver's supervision.
At some point in the video, the camera throws against the windshield to show that the car is driving at a speed down a two-way road. The digital instrument cluster can be viewed with "1[ads1]15" shown, but it was not immediately clear whether this number represented miles per hour or kilometers per hour.

A beverage holder with a bottle drink is attached to the car's steering wheel.
The camera turns away from the model's empty driver's seat to reveal a person lying on the back seat.
Videos that show Tesla drivers asleep or otherwise busy behind the wheel, are quite common, even though the car manufacturer commits its customers to remain in control of their cars while driving them on Autopilot.
The system requires drivers to hold their hands on the steering wheel. It activates a series of warnings if it does not detect driver feedback and disables itself if there is no response.
Tesla did not immediately respond to Business Insider's request for comment on the video Monday night.
