2 situations. A motorcyclist is in a crash with another motorists. Fristly the rider wears a helmet and suffers injury but lives. Secondly he is a sikh and dies through head injury for not wearing a helmet, the other motorist has to live with it.
either its acecptable to ride a motorbike without a helmet or its not. PC pandering is not an excuse until a turban is designed which meets the same safety standards as an approved motorcyle helmet.
