"Managed to avoid being killed by a blind motorist this morning, but my effective panic-braking technique saw me go flying over the handlebars and landing on my shoulder and head."

" few years ago, a bee flew down Sheri Taylor's shirt while she was cycling. She slammed on the front brake, which locked the front wheel, and she flew over the handlebars. "

There is a thread on BF which I will find when the search function is restored, about a guy who died due to panic braking and endoing when cut off by a truck.
