One nice thing about carbon when it fails, the underlying structure tends to retain some of its form, for example, when a carbon fiber handlebar breaks, it tends to stay attached but loses most of its rigidity at the break. When an aluminum bar breaks, it tends to just shear off at the point of failure. I'll let you guess which is typically more painful.

So true. Road bikes and mountain bikes are prime examples of carbon wheels at work:
