there a simple answer if u see lights behine u run. If there within 4 ft i called it game over and pull over just keep you eyes open. i remmber the one time i ran from the undercover SUV. I was flying down the rd and the SUV in front of me turn the lights on and i down shifter did 140 and pass him he shut the lights off. So i turn turn on a side street and lay low for a few mins then went home thru back roads im suprise he didnt catch me by listening to my pipe i had a jardine GP1 at the time.
