A cop's radar unit is parked 200m from a long straight stretch of a highway. Down the highway, 200m from the point on the highway closest to the officer, is an emergency phone. The cop points the radar gun at the phone. A car passes the phone and, at the moment, the radar unit indicates that the distance between the cop and the car is increasing at 72 km/h. The posted speed limit is 90 km/h. Can the cop fine the driver? A cop's radar unit is parked 200m from a long straight stretch of a highway.
