I often wonder how all of us lived - my parents had a 1960 VW Minibus - before the whole seatbelt thing became known, all four of us (ages ~ 1 to 8) would ride in the back trunk section, behind the seats, waving at the drivers behind us. Keep in mind, there was no actual trunk - a car hitting us from behind would have squashed us in that tin can before we would have died of injuries caused by being flung around/outside of the car. When my parents became aware of the importance of seatbelts, they were horrified, and IMMEDIATELY had the minibus retrofitted and we were never allowed to ride back there again.
