Yeah i hate pacing....they try to tail gate you to see if you'll drive faster so they can write a bigger ticket. I agree if its your word against the officers, you will lose everytime. I would fight it anyways, worse case, you'll end up paying the fine. At least if you fight it, you have a chance to win, get the fine reduced or get out of a ticket. If they dont show up for trial, you win automatically or if they have to go on duty at the time of the trial, they will dismiss the case and you win. Granted this is extremely rare, but you still have that chance.
