Are you unequivocally stating that this is only true for cycling?
Are you denying that a pedestrian falling would not derive the same benefit?[/quote]
well of course he would, of course a helmet would help pedestrians if they fall over - in icy conditions it would be sensible to put a cycle helmet on.
old and infirm, unsteady - good idea. - after all its not less dangerous than falling off a horse and they generally wear helmets, or more dangerous (being a pedestrian) than caving - they wear helmets or parachuting- all statistically safer than walking around.
so of course they should wear helmets.
so just because they don't and suffer the consequences your saying cyclists, parachutists, soldiers in war zones, mountain climbers, pot hollers, motorcyclists and all the others that do , shouldn't ?
is that the basis of your argument, because one group don't -and take quite high casualties - all the others shouldn't either - are you French?
