C'mon. You don't think the aircraft operators do the ticketing, do you? They do the spotting, the observation, the measuring. They communicate with friendlies in surface vehicles and have them do the ticketing. They use a new thing called "radio".
Ever notice the presence of markings on the highway, little Xs, perpendicular lines, or in some states even airplane silhouettes, that are 1/10 mile apart, convenient for groundspeed calculations with equipment as simple as a stopwatch? Like that Google aerial image above. That's speed-limit-enforced-with-aircraft territory.

Air war: Speed limit really is enforced by planes

With spring in full bloom, a Charlottesvillian's thoughts often turn to day-tripping by car. If you've ever considered those "Speed Limit Enforced by Aircraft" signs to be one of the heartiest haha's on America's highways, you may be surprised to learn that Virginia State Police really do enforce the speed limit from thousands of feet in the air. Anyway, aerial enforcement (as it's known in the police game) is very real. Virginia has been monitoring motorists from the air since July of 2000.
Here's how it works. Two officers in a Cessna 182 (Virginia does not use helicopters for speed limit enforcement) will fly back and forth over a pre-determined section of highway that has been painted with start and finish lines half-a-mile apart.

When a vehicle is caught speeding, the officer in the plane radios to another unit on the ground which actually makes the stop.
