Are You Really Speeding? part4

Did You Know that you car is Invisible until it hits 1500 feet away

By that time you have noticed the police car and have checked your speed.

Another disguise is the actual car you drive. The radar gun is fooled by fiberglass or composite bodies like Corvettes or kit cars. This material masks the metal so it is harder to pick up your car until you are very close.

Radar needs large quantities of metal to bounce off back to the radar gun with a strong signal. You can use this to your advantage by "masking" your car with others. (diagram C). In this situation, the police officer cannot clock you because the radar will pick up car A which is closer and bounces back a stronger signal. You will not be clocked if you stay behind car B or weave in and out of traffic, moving your way up, but staying behind the car in front of you for as long as possible, for "cover". However, once car B passes the police car, you are in full view of the radar. Hopefully by then, you have noticed the police car and have checked your speed.

In diagram D, the speed of the transport truck will show up on the police radar gun, not you. Even though you are closer to the radar gun, because he has a much larger surface area of metal, the signal returning to the radar gun is much stronger than yours.
