Comment: LucilleB, you and your denialist bike rider friends can keep challenging the cars but you are going to get the same result. So if you don't like the metaphor, then try this. Go to the Alaska Zoo and jump into the brown bear enclosure and get face to face with him and tell him to behave himself and not eat you. If you survive, good for you, but if you lose, then you took the same chance that bicyclists take with cars. It's hard to feel sorry for stupid!
