From what I saw he didn't make you change speed or direction and if he hadn't of parked up you wouldn't have caught him.
I personally think you're a muppet for going back and being the antagonist.
For every bad cyclist there's a bad motorist and for every bad motorist there's an arrogant cyclist who thinks they have equal right to the road.
Pay tax, pay tax on petrol, have insurance, an MOT, don't run red lights and maybe motorists will have some sympathy with what is YOUR choice to be a cyclist on something designed for cars, not designed for bikes.
Don't take this the wrong way, but, be careful when trying to have a word to these people. There's plenty of YouTube videos of cyclists getting gubbed for trying to talk to bad drivers, who turn out to be psychos.
Dear Mr Cyclist, you are a massive cock
Shame you weren't mowed down
