Well, I've been to traffic school 3 times in as many years
So, when I see a police officer on the road I do tend to get a bit nervous - especially after the time one pulled me over at 2 AM because my license light was out - freaked me out. So, if a police car is behind me it does make me nervous most of the time that maybe I'll do something wrong unintentionally. Otherwise I have nothing wrong with them, they're an important part of society.
