I think it's a Texas thing. The State Troopers are pretty full of themselves.
Can't say I wasn't speeding, but around here if you are going over 5 mph over the speed limit they'll give you a ticket most of the time. I got pulled over and given a waring for going 3 mph over the limit, I knew he would give me a waring so I didn't go off, but damn dude, quit wasting my time.
