The cyclist was only doing what was right by moving in front of the Audi. The cycle area us there to give cyclists an advantage at the lights etc. and encourage cycle usage. The guy in the Audi was being a complete tw@t, and deserves to go down for assault and dangerous driving. By the way I cycle for fitness/pleasure and drive to work.
You'll notice that the Audi speeds off straight into another set of lights and has to stop. I suspect the lights are set to always do this, so the area for cyclists is a sensible precaution, to allow them to be ahead of the traffic at this stop and the next. Mr Audi was a dick, Mr Cyclist was in the right, but handled it badly, but Mr Audi was then a bigger dick and really showed himself up.
Given that most the cyclists I have encountered of late are utter **** nuggets I find that quite amusing.
