I'll probably get run out of here with torches and pitch forks for saying this and PLEASE, do not take this the wrong way but I think a lot of times bicyclists have a chip on their shoulder as if they are just waiting for some driver to wrong them so they can unleash their righteous anger on them. How would I handle the same situation if I were driving a car rather than a bike? I would have said "Nice driving #@@^%*$!" to myself and go on with my life. What you did by rolling up right beside them is the equivalent to getting out of your car, running up to their window and admonishing them. That type of behavior will get you hurt or killed.
