Good link. It would be a good idea if drivers were to understand that their automobiles are subject to the laws of physics. (Some police bureaucrats have proposed using an "electronic beam" to shut off the engine of a speeding car.)
But, technology rendering radar guns to be as reliable as dating methods.., will it also shoot a beam to shut off the engines of speeding trees? I mean if we can date saplings at 20,000 years old, I guess we should be able to stop a tree that's moving in excess of 55mph according to a radar gun. Calibration or no. ROFL
