RLJ (Red Light Jumping). (The definitive bikeradar thread)

Cyclists shouldn't use pedestrian crossings any more than they should ride on the pavement. Unless they actually carry the bike, in which case they become a pedestrian. A rider has no right of way across a zebra crossing and you are not obliged to stop for them. Lights of course, you 'must' stop for.

So no, I think you have every right to be annoyed.

Sorry dude... the legalities are less important than common sense.

I rode towards old street roundabout recently with a less experienced rider. We got off and pushed the button. Will do so again if required.
