GP, your arguments on personal responsibility have me a bit confused. Yes, I agree that it is stupid and foolish to ride without a helmet. Yes, it is somewhat selfish, too, if you have loved ones that depend on you.
However, it is a personal responsibility choice. If I choose to not wear a helmet, I am choosing to be a selfish bastard. The last thing I want is the government stepping in. Yet, that is what you are advocating.
If I choose to not wear a helmet, that's my choice. Not the government's.
Addressing another comment in this thread by Hellfire:
If I choose to not carry health insurance on myself, that's my choice. Not the government's.
It can't be both ways. Saying no to helmet laws based on freedom of choice yet advocating mandatory universal government healthcare is contradictory.
