My favorite quote from the article:

"Radar will shoot further than lidar, up to 1 1/2 miles on a long open stretch of road. Because of the cone-shaped pattern of the radar waves, an officer parked at the side of the road can capture speed data from vehicles in both lanes and both directions"

Wow.. and does he use a telescope or binoculars to get a visual estimation of speed on vehicles from 1 1/2 mies away, also??
