I think the people supporting this are people who have never had an accident or never had an accident involving their head or face.

I have had two accidents and both times my helmets was involved. I could of lost my eyebrow and fractured my eye socket without it.

No I will ALWAYS wear a helmet not matter where I ride and how slow I am going. A friend had a slo-mo accident and ended up with serious head injuries and he was almost stationary (and no car involved, he just over balanced).
