I don't speed. Look up what a speed trap is. As an example, one that got me was a 50 MPH speed limit going down a mountain that twists and turns. The last dozen or so yards of the mountain, and around a turn, it suddenly becomes 40 MPH with no warning or time to slow down. Cops camp out at the sign and pull over people with out of state plates who are slowing down from 50 MPH to 40 MPH all while going downhill.
