It is very common that road accidents happen and the usual people involved are those who ride the motorbike. It may be a real race or a mere negligence or recklessness but there is one reason why some survive. They wore a helmet. Many do not, or feel that they need not, perhaps due to overconfidence, or because of plain laziness. Some are not comfortable with the ventilation that does not happen inside the helmet. That is one of the reasons why the HJC RPS-10 is one of the best, because of the air flow top vent that makes adjusting easy because of the glove-friendly dials.
