I have found that when someone is all hyped up and tailgaiting you, that its a lot more fun and satisfing to laugh at them when they fly by!
Not that this is a good thing, but nothing pisses off a stupid driver more than laughing at them!
Another favorite is to hold the finger up against the window and act like your just driving, its amazing the double takes pissed off drivers will do.
Havent done either of them in a while. Sometimes I will weave a bit in my lane and that usually gets them to back off a bit.
