I live out in a subrural area... and on Friday and Saturday nights, if you're on your way to the dragway (75-80) the cops won't mess with you at all... because usually they're on their way there also, to watch. I've heard reports of people speeding by in cars with no tags, no exhaust, etc. etc. etc.... as long as you're going to race, the cops are fine with it. Probably only works in an area like mine, though.
