Well, I'm not sure that the next step of abuse logically follows either--isn't it kind of like the "gateway" argument about pot?

I drove a truck all over the place and the only cop I ever had a problem with was a glorified security guy at the John Hancock building, who insisted we had to take our 13'2" truck down into the 12'11" entrance of the loading dock. I've had many encounters with cops, had a busy juvenile period, but always got along fine on basic manners. I do real well with a bit of putting my hands out the window when I get pulled over, as basic courtesy. Usually get off with a warning and a thanks. By "usually", I mean I've had one ticket in my life. Oddly enough I learned and first tested the hands thing in Richmond VA, when I lived there.
    Now I live in KY, can't compare the cops, but the morons who drive trucks on I-65 keep about 16 inches following distance from cars ahead of them. With two open passing lanes beside them. Nobody does that, anywhere else--it's the first thing a truck driver learns not to do. One day, when I have the time, I'm going to follow one of them to their next stop, and they'll have some 'splaining to do. The ignorant cowboy F-heads.
