A motorcyclist's coat worn backwards leads to his demise.

Snopes

It seems a motorcyclist was riding and wearing his jacket as he always did, backwards; this unorthodox method made the jacket more airtight and was more comfortable while riding. Of course someone had to always zip and unzip him. One day the cyclist had a minor accident and fell off his bike. A "Good Samaritan" saw this from his car, got out, saw the cyclist and determined his accident caused his head to be turned completly around. He felt action was necessary so he tried to twist the cyclist's head back to its proper position. This of course broke the motorcyclist's neck.

There's more if you click on the link. Snopes classifies this as unknown. Do you think it's true or not?
