Laser speed detection questions

Speed kills? What a load of shit!

More than half of the 11,000-kilometer German Autobahn system has no speed limit. It is perfectly legal there, for example, to pass a police car at 210kmh. In fact, according to Mark Rask, author of American Autobahn, the average speed for cars is 130kmh; at any given moment, 15% are traveling 155kmh or faster. Surprisingly, the Autobahn is safer than U.S. highways. In 2001, the death rate there was 27% lower (0.59 deaths per 100 million vehicle miles traveled versus 0.81 for the U.S Interstates).

muz, my original question is a technical question, not a sook. I still dont know how anyone but the best can accurately hold something much shorter than a rifle, without a shoulder support and accurately pinpoint a car for over a split second, over 100m away.

As I said before, the red dot locks onto the car and follows it as long as the car is still visible within the scope. The operator simply has to ensure the car remains in the field of view, not hold the dot on the car.

You could always try stopping and speaking to the next highway patrol officer you see using a LIDAR, as long as it's not too busy. I guess they'd simply shoot you for daring to speak to them in Victoria though.

Most LIDAR units have a wire frame 'stock' that is designed to be used like the butt of a rifle. Thats not the point really, because its not a gun, its a LIDAR unit. Its emitting light which travels rather fast, no matter how much the user wobbles, he cant wobble fast enough to cause any significant shift during the time when the light is going to the target and reflecting off it. Even if it did matter, the beam is wide enough at that distance that even if the operator changed his point of aim from the left headlight to the right headlight it would still cover the vehicle enough for an accurate reading to be obtained.
