I suggest the next time they retire a police cruiser, they simply park it on Kelly Drive near Fountain Green Drive and place a mannequin in the driver seat sporting a full policeman's uniform. They could even set up a relay connected to a simple circuit that would randomly flash the lights to achieve the look of a real cop in the cruiser.
Move its location occasionally but I guarantee that the average speed of motorists will be very near or under 35 mph. And it costs the town next to nothing.

That’s exactly what’s done in the town just north of mine. Everybody knows about it so everybody ignores it and speeds on by.
My hometown of Nampa, ID, did that a few years ago (actually, I think it was a wrecking yard that put the car out). They removed it after the dummy inside was found to have several bullet holes in it.
