That sucks, Trigress. Glad nobody was hurt, that certainly isn't always the case when drivers behave like that.
IMO there's only one thing to do with drivers like that - get the license plate no. and report them to the police. When they act that aggressively NO amount of arguing, pleading, cajoling or threatening will make them see differently, not at the moment at any rate. He'd made up his mind that you were in his way, and were deliberately provoking him, and he felt entitled to "get back" at you. There's an amazing amount of drivers who feel this way, and who are completely clueless as to the very real danger they put cyclists in. They just don't get it, that a cyclist can be killed by just being bumped "gently" by a car, or seriously hurt by hitting the pavement.
More normal drivers seem to respond to cyclists acting responsibly, moving to the side when they can, respecting red lights, waving a car past when possible, but drivers prepared to brake in front of a pack just couldn't care less. They just see red whenever they see anything that looks like a cyclist on "their" road. Funny thing is - you wouldn't see them doing the same thing to a slow-moving tractor... oh, that's right, that would make THEM the weak party.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
