I assume that you can't go to driver's school on this one? Is 90+ just more expensive than, say 75? If you can go to driver's school, pay the fine and be careful not to get popped again for 18 months. That way it doesn't go on your record. It's only money, if you can keep it off of your record and your insurance company doesn't see it. Otherwise, unless you completely beat the ticket, it will count for the same even if you get the speed, and the fine, reduced.
