I have this same fear, but not quite as bad. When ever I am driving, and see one, or one gets behind, or in front of me, I get panicky. I know I am not doing anything to be stopped for, but I can't help that feeling, and I have the same feeling with anyone with any type of authority. Before reading your post I thought it was normal, but I now realize that it all has to do with the way I grew up, and my fear followed me through my adulthood. (((((((HUGS)))))))
