No, they treat you differently if you have an attitude problem, or drive a vehicle that looks it was built with an attitude problem. You may not think you drive badly, but have you seen what your driving looks like from 2 cars behind you? Did the cop that tailed you for 40 mins actually pull you over for anything? I'm wagering not... and if this is the case, you should be grateful he was just giving you a bit of a scare in the rear view mirror, rather than just pulling you over and doing you for something ludicrous. Reminding you he is there is effective road policing. ...and to reiterate what Hiro/MR22ZZ/DJKOR/Brad! have already said... if your tint is legal, you have nothing to worry about. If you get pulled over and checked with this machine, you will only get booked if it is too dark. Likewise; if you don't drive around showing off the sound of your intake, you are not going to be a target for the blues and twos. Drive within the limits, or quit whinging. Please choose one...
