Around here, most of the time, I think they are just admiring the bikes themselves.
I have been stopped a few times (this was years and years ago), I only received the pretty pink reward on two different occasions. I should've been awarded great big pink rewards every time. Most of the LEO's were preety cool and just told me to slow it down and be more careful.
Stopped once in Charlotte, NC when the GT Mustangs were being used as the State Trooper cars. Yes this was the last pretty pink reward I got, but the trooper wsa really nice. I got him to raise the hood on his car so I could check out the engine, he let me climb under it (as far as I could) to check out the suspension. He even pointed out some of the minor differences in the State Trooper cars and the regular civilian cars.
IMO most of the time it is your attitude that gets you the big ticket, a warning, or a compliment on your bike.
Of course if you are willing to run or are super speeding that could make for a real bad day.
