This happened to my very young son
Not on the roof of a Landrover, but on a sledge on a snowy hill. He went shooting down the hill, but somehow managed to turn sharply and end up heading straight towards teh barbed wire fence instead of away from it, as planned (and as everyone else went). Cue me running down the hill as fast as I could, yelling at him to lie down. With seconds to spare he lay down and passed happily underneath the wire. When I got to him he had a huge grin on his face, squealing "again, again!"
