I have a feeling that most cops, unless they work for one of the ridiculously self-righteous districts in MD or VA or something, understand that speed enforcement is largely bunk. Reckless driving is what police are supposed to be going after -- but that's harder to prove, so they fall back on the only thing they can use a machine to determine, which is speed.
I think most cops also understand that it's not in their best interest to throw the book at everyone who even slightly violates any law. That would degrade the public's trust, not to mention it'd increase their own workload as more tickets would be contested.
So, if you're driving attentively on a totally open and laser-straight stretch of road, and you're nice to the cop when they pull you over for just going too fast, they will be inclined to go easy on you. If you're weaving in and out of traffic around blind corners and then you make life difficult for the cop, they will become MUCH more interested in you.
There are always exceptions, of course, but I feel like this is the general trend -- i.e. maybe 60%-80%.
