При столковении о неподвижное препятствие со скоростью 60 км/ч на человека воздействует сила равная 3 тоннам. Кроме того при наличии подушек безопасности, ремень задерживает полет человека к ней, давая ей время раскрыться. А скорость раскрытия подушки около 300 м/с, и сила ее удара сравнима с силой удара боксера тяжеловеса, без ремня она убивает человека запросто, ломая ему шейные позвонки. Так навываемая хлыстовая травма позвоночника, и сидит такой человек в машине, на нем не царапины, только вот мертвее мертвого.
