If you have a short commute and still don't cycle to work, why not?

This is a short article about the 10 chief myths that keep people from biking to work. It's from the Guardian in the UK and I want to point out that it is written by a Member of Parliament. Anyone here imagine Stockwell Day or Peter McKay biking to work? Stephane Dion, maybe...He doesn't seem to mind being seen as a bit nerdy. But nerd-in-chief Stephen Harper? Not in this or any other lifetime.
