Was there any action taken against him or was just a case of yet another cyclist paying the price for minding his own business as you say.
It is really annoying the standard of driving and any of us that ride bikes on the roads have all had similar experiences, but hopefully not as bad as yours. There is such a debate about responsibility and plenty of motorists don't think they are doing anything wrong most the time when they cut you up, they reckon they have priority, they pay their taxes and all that crap.
I wish the law was changed to make them responsible and they would have to prove they were in the right, because presently they just seem to get away with most of it and the cyclist nearly always seems to be at fault.
Sorry to hear about what happened to you, and I hope this is the start of you getting your confidence back and enjoying the pleasures of getting out and riding.
