You don't think the force exerted on the carbon fiber is at least as great while flying a X ton plane? Being afraid of a material is ridiculous. do we need to find the Trials guy on the carbon bike and rims?

as shown with the cannondale bike.. if you hit something hard, things will break. Not to mention that just because it breaks in multiple places they all happened in the crash. Once one tube goes the support structure is gone and other things will fail. If someone takes your leg out and you fall down and break your arm.. your broken arm wasn't caused by the person kicking you.. it was a separate condition.

if you're hitting another person or a car at high speed the bike is the last thing i'd be worried about.
