Getting pulled over by cop?

IF they remain in the patrol car after you stop, they ARE waiting for the computer to return information on the car and the registered owner. The LAST thing the officer wants at a traffic stop is for the driver to be nervous. A nervous driver is likely to do unpredictable things. They FOLLOWED you for a mile or two for one of two reasons. 1. To determine your speed by pacing. 2. To run your plates BEFORE they stopped you. The DID NOT actually tailgate you. Not even the officer will ever know for sure what they would have done if you had slowed down before they initiated the stop.
