I'm of Tsybil's persuasion -- I try to keep it under 100mph. That's the "exhibition of speed" limit (a 2 point violation). I'm one of the few polite speeders, though. I don't weave madly around traffic just to maintain my 90mp habbit or run up on someone's bumper to scare them off the road.
You just have to be smart about it to avoid tickets. It's always fun in traffic school to answer the question "so why are you here? and how fast were you going?" with 95mph. Gets a lot of eyebrows. You can't go to traffic school unless the cop writes you up for going only 72 or less (limit is 65).
Thing is, if you notice a potential cop right away (like when he's getting on the highway) and don't give him time to clock you, he has no evidence. He knows you were speeding. You know you were speeding. He might pull you over or might not. If you're polite and don't hassle him, he'll just give you a warning or at worst, write you for 72.

Oh, fun story about getting pulled over. 95 on way up to Tahoe. This other car noticed my speed and decided he needed to "beat me". Fine, he can break trail. He's weaving around and being a jerk about it. Cop pulls us BOTH over. My idiot passenger takes this oportunity to jump around in the seat and start rummaging around behind us (as if he's trying to "hide the drugs" or something else damn suspicious). He's not blonde, but sometimes I wonder. Fortunately cop didn't notice or chose not to search us. Talks to us. Talks to guy in front car.
Then he comes back and asks me if I know the guy in front. Nope. Gives back license and reg, then tells me to "Your lucky day. That guy is a real asshole. Drive slow. Now get lost."
Be nice to cops when they catch ya on a traffic regulation. If you can manage to act a bit scared, that can sometimes help, too. This can be hard if getting pulled over is a regular thing.
BTW, I get a "good driver" discount on my insurance. Traffic school FTW! Too bad they discontinued the comedy shop traffic school thing. Those were fun.
