Go to the drivers level. I've been riding bikes and living w/o a car for over 10 years now (24 years old) I have tons of experience with drivers. What I do probley pisses a lot of elders here off, but flock em too.
Run lights (if its clear), screw signaling (people dont know them anyhow), let them honk, let them yell.
Yell right back. Flip the bird. Do what you gotta do!
