Choose to go to court. Tell the judge that you feel it's unfair to get a ticket because you left upon request from the cop. The court will schedule a hearing and it's most likely a year from now. Usually, the judge will either throw out the case, in which case, you won't have to pay, or he will reduce the amount. You have nothing to lose by going to court.
either pay or go to the court and follow the court decision. Do not try your luck to ignore or escape. Once there is a court decision, even without your presence, the record will follow you and it takes a long time to clear it, unless you are not going to stay here.
