This was a fascinating program. It explained and demonstrated over and over again how laser based speed guns were completely innacurate. They gave a speed of 36mph on a vehicle that was parked! The further away the vehicle the wider the spread of the laser, and easier it is to pick up a reading from another vehicle. If the light beam is moved on the vehicle it can change the reading dramatically. In another demonstration they had a vehicle traveling at 29mph and the gun when used on a tripod gave 36mph.
What chance do you stand???
