Spotted...

Some idiot on a blue road bike, running reds whilst pedestrians were trying to cross.

First light: Waited for pedestrians, caught up with him, "Hey Lance Armstrong, Why don't you wait for the pedestrians?"

Pedestrian cross-walk: Shouted "Fucking Dickhead" as he weaved through walkers. Caught up and passed.

Again zoomed through a crowd of people at Goswell/Clerk intersection. Someone even said "Bloody unbelievable".

Third long stretch between Goswell and Old street, caught him up and passed again, "You're not very fast are you mate?"

Then I left him behind, anyone here?
You oughta be ashamed of yourself, plus you are slow.

I owe you +ve rep for that one :)
