You can't underestimate the subconcious hatred some people have of cylists and cycling.
On Monday morning I was trying to get a Boris Ken bike from a stand by Charing Cross which wasn't working. I was on the phone to the call centre to see if there was a problem with my key or something and another bloke was stood beside me waing to see what they said.
A painter and decorater in a van then drove past and shouted "Fucking cyclist cunts!" at us whilst we stood there, not on bikes just near bikes in shoes, shirt and tie with not even a helmet between us.
I thought it was hilarous at the time but christ what is going on in your head that the sight of someone just standing near a techno bike rack can send you off on one??
