MAN USES MATH AGAINST RADAR

Most of us, upon receiving a speeding ticket, simply pay the fine and then go on about our business. Zamir Bavel, a National Motorist Association member chose to argue his ticket in court – and he won.
Writing in the NMA Foundation News, he reports that his argument was based upon the scientifically verifiable premise, that the angle at which a police radar unit is reading in relation to the auto’s position will affect the accuracy of the presumed speed. The so-called Cosine Effect posits that the radar read-out will be the same as the clocked auto’s speed only when the car is coming directly toward the police officer’s radar gun. Either side of that line, the speed will register higher or lower respectively than the actual speed.
As Bavel writes: “The closer the car comes to the position of the radar gun, the larger the angle, and the smaller the radar readout. By the time the car is even with the radar gun, so that the angle is 90 degrees, the read-out on the radar screen decreases to 0 mph.”
The judge who listened to Bavel’s defense, dismissed the charges. Bavel reports that he has since been approached for details by local attorneys, and colleges have used his case in their calculus classes.
