"Suppose the law is changed allowing my wife and me to choose not to wear our helmets. It's late afternoon and you, sir, have been in a committee meeting all day and are tired. You get in your car to drive home. My wife and I are in the lane next to you and our bike suddenly swerves to avoid another car. The rear tire of my bike clips the front of your car and we go down. You arrive home and tell your wife that a rider is dead. It was our choice not to wear helmets. It was our life. But you had no choice. Although no fault of your own, and it happened too quickly for you to react, everyday for the rest of your life you will remember that you killed someone."

And then there is the law requiring seat belts...child seats...everything that makes people safer...
