just to put the post in some perspective and not quite a selective view of the program. the professions who deal with this type of injury are in no doubt about the benefits of wearing head protection whilst cycling.
Is that why in 2011 the British Medical Asociation voted against helmet compulsion by 68%?
The medical profession is certainly not unanimous in its views on helmets with many against compulsion, and many also disagreeing with their value in preventing injury.
Do you really think that the medical evidence is unequivocal, and should be believed "just because a medic said it"?
