Not only was the guy fortunate he hit a vehicle, he was fortunate on where he hit it, how he hit it, and the type of vehicle it was.
That was the first though in my mind. When he hit, the car instantly crumbled and i thought to myself that may have just save his life. The fact that he fell flat, on his back instead of his front (no idea if that makes a difference) and that the roof instanly caved in. I honestly think he bounced off of the roof, but could be mistaken, because hit landed on the ground flat on his back and never moved. the car was moving as well so it really was a one in a million shot. My mind is still blown.
