Wow, videos of pros on cutting edge equipment experiencing failures. That should never happen. But it does - race cars and boats experience mechanical and electronic failures, sailboats have masts that fall and keels that come off, skiers have poles that break, surfers get hit in the head with their boards, bats break in baseball, and on and on.
Anything can fail when pushed to the limit. But, the odds of that happening are pretty remote. More people crash because they don't unclip their pedals than from carbon frames assploading.
