I found the article to be interesting.
It seemed to dwell a lot on a single case of a broken fork & accident where the rider apparently suffered a concussion, but was able to describe the feeling moments before the accident (despite the concussion). Hopefully there were witnesses.
Many of the broken carbon fiber posts on the web are based on crashes causing the broken carbon rather than the broken carbon causing the crashes, although I presume there are a few of the latter.
There are a LOT of carbon fiber forks out there.
