5-Year-Old Boy and Grandma Survive Being Run Over with Only Minor Injuries [VIDEO]

How did this 5-year-old and his grandma survive being run over by both tires of a vehicle with only minor injuries? I've watched the video multiple times and I have no clue. While both survive the accident, the video is a bit disturbing to watch. 

To me it looks as if he does a push with the car on his back to get out of it! Maybe he is a real life Superman?
