The world is full of bizarre events so it is not surprising when one sees a car goes down the road but without a driver in it. The most obvious explanation would be paranormal activity but it wasn't the spirits driving the car instead it was a man dressed as a car seat at the wheel on the road in broad daylight.
NBC Washington reporter Nick Tuss spotted the car self-driving leaving him shocked yet curious about how it worked. He immediately went close to the car and saw a man dressed in a beige and black car seat costume driving the car by holding the steering very low so that nobody could spot it. While the reporter tried to question the man at a signal, he simply drove off because anything could be revealed.
Interestingly, the self-driven car trickery was an experiment by Virginia Tech Transportation Institute for a study they were doing on self-driven cars. It definitely seemed to work out because the deception seemed real to other drivers on the road.
