Enforced By Aircraft

As I'm driving through Tennessee on my way to New York, I notice a lot of the same signs in every town until Virginia. "No Radars, Speed Limit Enforced By Aircraft." Now it could be just me but I don't think they want you speeding. All I could imagine is the car in front of me accelerating about to pass a car and suddenly, shhhhhhhhhhHHHHHHHHHH DOOM BOOOOOOOOOOOOOOM SHHHHHHHhhhhhhhhhhwhooo. Any city that is willing to kill those speeding means that they are taking their right to exercise the death penalty way too far, as another guy speeds up and DADDADADADADADADA. So this is a forewarning to those who think, " 70 mph? I'll do 75." It could mean your life!
