you might win, you might lose, but either way at least you have a chance to get away scott free. And if its a big ticket, you typically have anywhere from 2-6 months to save up to pay it (if you lose in court they can require you to pay the fine in full before you leave).
I've had two speeding tickets. One was a six-point ticket (out of thirteen) for doing 76 in a 55, $262. The other was just a week before I moved for doing 75 in a 55 in a work zone (double fines). The cop could have shot me to hell with over $3000 in fines and three days in jail, but instead he just gave me an $82 ticket and marked it as going 9 miles over the limit in a non-construction zone.
