you know, there's been a couple times I've been pulled over (one was 15mph over the limit by a state trooper in tx, the other was 21mph over limit by my local SAPD). in those two instances, I didn't get ticketed (the trooper game me a written warning, the sapd went as far as me signing the ticket, then him giving me both his copy and my copy and telling me "to think about it").
of course, I've been ticketed for doing even 10mph over the limit.
now I just don't speed, and I don't have problems with cops :dunno:
loud exhaust notes draw attention when the cop might otherwise be looking down and not notice you.
it doesn't matter what you drive, if you get caught by him speeding, he'll get you. I've had people I work with get pulled over in minivans for speeding.
