For the most part, radar detectors in a SVX will let you know you are going to get a ticket if you are speeding. They will not give you ample warning to slow enough to avoid getting a ticket. If you are guilty, pay and move on. The speeding traps here in Washington State are so bad, I drive the speed limit and use cruse control to stay there. I go through 2 or 3 in a 20 mile drive to work. I don't want a ticket, so I drive the speed limit.
