This County Mounty doesn't have radar anymore. Don't use it in my neck of the woods, but when I was in Truckee, Ca. we used radar. It's hard to get distracted with the looks of a car speeding at you, because radar units emit a tone indicative of the speed of the object coming at them. The slower you are moving, the lower the tone. The faster, the louder and more high pitch it sounds. Legally, officers are to estimate your speed visually, then turn on the radar. Yeh, RIGHT!!!!!! I would catch them at 90 in a thirty five along Donner Lake, About a five mile fairly straight stretch. I'll admit, attitude is everything when deciding to cite or not. On more than one occasion, I just gave a verbal warning to classic cars. Hell, They are just cleaning out the cobb webs. What's wrong with that. It was the punk kids in their POS cars and driving wreckless, and usually high or drunk that I would come down hard on.
Just enjoy the cops appreciation of the car, and watch your speed, IF YOU CAN. Drive safe and respect the car. Mike
