WTF? Selfish behaviour whinge

So I thought I'd rant a bit too.
Today I went for my first decent sized ride since the shoulder injury I gave myself, from Oxford to Reading. It was a glorious ride, except for the beginning and the end.
At the beginning I was adjusting my straps on my bag, so was riding no handed, and so had moved to the centre of the road. Then a taxi driver semi-overtakes me and has to cut back in, because there is a bus coming the other way. He knocks my front wheel, and I just about gain control of the bike again, a little miffed by the idiocy. So I swear at him, and he drives off at speed, straight through a red light. Eventually (not that long away) he gets stuck behind a bus, and I rap on the window, demanding an explanation. Fscking cunt.

Anyway thats a side story:
The real story happened when I got to reading. I caught the train back, and having never taken a train with a bike before, just put it into a carriage, and then relaxed. Ten minutes later, after making a few friends in the carriage, from having to move the bike, this total [gender unknown- seriously no idea what] bully twat of a conduct comes up to me and says that I should of put it in the bike store (true but I had no idea). I reply calmly and nicely that I didn't know and there weren't any station staff around to ask, and he/she goes balistic and is right up in my face all threatening like, saying "there were plenty, etc, etc." and getting really irate. I restated that i didn't see any and he/she just got madder and threatened to chuck me off the train at Didcot.
Eventually, the bully left me alone. I was a bit dumbstruck by the sheer rudeness of this woman, and a nice guy comes up to me and gives me his card, and says ' make a formal complaint'.
I mean why do people not like cyclists?
And I'm quite a nice, easy-going guy. It was unbelievable.
I'm still in a bit of a shock, does anyone have any idea how to make a specific formal complaint to First Great Western.
