I used to do this all the time as well, and then I started noticing that it only increased the rage that I felt and also the rage in the other drivers. It finally came to a head when a car tried to run me down between multiple lights. My new form of riding in the city is to be 100% defensive all the time, but not in a give up my rights as a cyclist way. I assume cars will do dumb things (because they always do) so I avoid their blind spots, never pass on the right, alsways take the entire lane so that a car can not pass you if it's not safe (only do this in the city), when traffic is slow assume cars will jump quickly around in lanes etc. Many people get angry and defensive when you yell at or reprimand them. The goal is to try and inform them of their poor driving without increasing anger on both sides. Now I do this with a look, and no anger, and people tend to respond to that apologetically.
