Jen.Jen, it helps when you realize that drivers truly don't mean it personally. It feels like it when you feel vulnerable, but at that split second grandma-in-a-hurry just thinks "DANG, one of those dern cyclists in front of me AGAIN!" and takes out on you whatever aggression she has built up from before. It has quite little to do with what you're actually doing, unless you've been riding like a jerk and stalling traffic for miles.
It sucks sometimes, but yeah, we should try to be ambassadors. Very polite, genteel, kindly ambassadors, by our wonderful example showing all these poor people how the world could be a better place

Re road rage: read an interesting article once on how people tend to identify themselves with their cars and view them as an extended version of their personal space. Which might explain the aggressive behaviour when drivers feel "pushed", while still safe inside. On a bike you might feel pushed but vulnerability makes you less aggressive.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
