Well looks my actions opened a can of worms.
The way I saw it at the time and still do now is this. This woman delibrately drove at me and forced me off the road. I did Sylvs tatic of the old knocking on the car and shouting but she just glanced across and carried on moving over towards me, she was quite prepared to damage her car by knocking me off so I just granted her wish and did the job for her. Simple as that. If it had been a genuine accident and she hadn't seen me then I would have just told her to keep her eyes peeled for cyclists. The fact is SHE WANTED ME OUT OFF THE ROAD BY ANY MEANS. I tried to talk to her and ask her politely what was she doing only to be told I was in her way and I should learn how to ride a bike.
Adam, I doubt she'll go out trying to kill a cyclist, she'll just carry on the way she is, being an ignorant driver but this time her ignorance has cost her a few quid.
Live by the sword, die by the sword I say.
As for thanking motorists who give way to me or show me respect by waiting to overtake me when its safe, I always stick up a hand to thank them.
