They parked an unoccupied car along Clayton Road and have been moving it from spot to spot as a warning of sorts.
Leaving the car parked on Clayton has a psychological effect. Motorists slow down when they see it and they also obey the 40 mile an hour speed limit. It is working and most people who drive the street or work in the neighborhood think it is a good idea.
But, drivers should beware. It is not always unoccupied. Sometimes an officer is sitting inside with radar, and guess what happens next.
The police also rotate the location of the car to keep drivers on their toes and the brakes.
