I'm still waiting to see the study of how many accidents are caused by the wearing of a helmet.

There is a thing I call helmet fatigue. Anyone want to dispute that hasn't ridden a 600 mile day. They haven't experienced the vibration causing drowsiness and fatigue reducing your reaction time and alertness. If you doubt it exist take a ride of say 300 miles with a helmet, then take it off and ride 5 miles. You'll see what I'm talking about!

Loss of peripheral vision is another factor. Especially with some of today's models.

Loss of sound perception is another factor.

I could go on beating this dead horse but let me just say there are far too many inexperienced people passing laws that restrict my freedom to make my own decisions.

PS. I do wear a helmet at times, but I think I'm the best judge of when I need to take it off and ride unencumbered.
