Nate, how is a helmet law any different than gun laws that restrict ownership?
Uh...there is no Constitutionally guaranteed right to ride without a helmet.
The Libertarian in me wants as little government interference in our daily lives as is possible...just shy of anarchy. Society's attempt to "protect" itself financially from the idiotic actions of some, have always infringed on the rights of others. I wouldn't ride a bike without a helmet for all the tea in China...but, the Conservative in me can't bring myself to force another to act as I see fit. I think a reasonable work-around to the whole helmet issue would be to require anyone wanting to risk splattering their brain all over the nearest Armco barrier to:
Sign and carry a DNR release.
Post a bond or carry an assigned risk insurance policy.
There are enough stupid people in this world...that we can afford to lose a few without having to pony up an enormous hospital bill when one of them doesn't quite make it to Darwin Award status.
Otherwise...I'll just keep tuning in "World Worst Drivers" and shaking my head.
