Or Brain science..........:D

First thing I ask when people get speeding tickets is if they were over the limit. If you are, then you have no one to blame but yourself. Sure, some officers don't care about 5-10 over, but when you are over, and you get pulled over, you're always leaving it at the discretion of the officer. You can always go five under the limit and not worry about it. That strategy has worked well for me.
