In case you didn't know, Tesla vehicles are capable of "autopilot" mode, meaning they can almost fully drive on their own. The car utilizes multiple camera, a radar, ultrasonic sensors and a computer to navigate roads and surroundings.
Amazingly, the autopilot mode can sense when people are around the vehicle and react accordingly.
One dude with a Tesla tried out autopilot mode while going through a cemetery and something really strange happens. The display shows that there's a person nearby the car... except no one is actually there. And since it's in a cemetery, you can draw you own conclusions!
