I got to thinking today that all of us on here have little "tips" and "secrets" that we use to evade/detect radar traps, so why don't we all help each other out? If each of us post one little secret/tip/help that someone could use to evade radar, we could virtually have an encyclopedia of information.
1. Watch and be very attentive to brake lights ahead of you. It is pure human nature to tap your brakes when you see a radar trap even if you're not speeding.
