Matthew - have you ever considered having a couple of driving lessons to help your roadcraft and understanding of other road users and why things happen. Everyone makes mistakes on the roads, cars, bikes, milkfloats - almost all of the time the incidents you report are not deliberate, just a miscalculation in a split second. Most drivers aren't out to get you (really), although your part of the world does seem to have a high proportion of aggressive so-and-so's, although sometimes your actions aren't conducive to an agreeable outcome.
Just a suggestion
I think it's the driver who needs extra lessons, as Matthew did nothing wrong.
