"sleeper: something or someone that becomes unexpectedly successful or important after a period of being unnoticed, ignored, or considered unpromising or a failure"
Ever since the first police car rolled out of the factory, motorists have been trying to avoid the eye of "the man." Everything from radar jammers to just plain slow driving have been employed by the general population. While radar jammers and detectors have their place and driving slowly doesn't, the best way to avoid the 5-0 is by simply not drawing their attention in the first place. In other words, drive a sleeper.
