I had the misfortune of working a deadly crash years ago involving kids in the bed of a truck. I was driving the same year, make, model an color truck at the time..... I did not know the family but what I saw will haunt me till the day I die. I did it as a kid too but seeing it today makes me sick...
Also years ago we went to panama city for a week. We were cruising around one night. I was driving an everyone else was in the bed at the tailgate. Someone pulled out in front of us an I just missed T-boning them.
