@OP: No offense, I'm not trying to say it was your fault, but you handled this situation incorrectly and hopefully you can learn from it. Yes, it can be scary when an angry motorist tries to intimidate you, but getting out of the way often is more dangerous than "staying the course" even if the result isn't as dramatic as in your example. If you can safely let the car pass that's an option and maybe the first instinct of many people but it often isn't safe. If you let yourself get pushed into the door-zone or out-of-traffic (which means you have to re-enter traffic again) you're just putting yourself in more danger than you are already. Yes, a big car honking at you is uncomfortable, but even if the driver is very angry indeed, chances are overwhelmingly he won't hit you. Cyclists get hit when the other party doesn't see them! Everyone who drives a car can lose his cool sometimes, that doesn't necessarily say he's a bad person, driving simply can be a very aggravating activity, but only a true psychopath would act out their anger by deliberately hitting a cyclist.

If it happens again to you, don't panic, stay calm and keep doing exactly what you've been doing until you can either let him pass safely or the situation gets resolved any other way (red light, you going a different way than him or whatever). The best way for cyclists to be safe is to be visible, predicable and consistent in your movement imo, not to be push-overs.
