In the heart of Leon, Mexico is a street that appears to defy the law of gravity. In the video, a driver puts his car into park, releases the handbrake and keeps his feet off the pedals. As he does so, his car appears to roll uphill all on its own. Many believe this to be paranormal. However, there is a simple explanation – it’s an optical illusion. Due to the layout of the surroundings and a distorted horizon line, the car is actually rolling down, not up the hill.
