^^ Still done. Watch for T shaped painted marks along the shoulders. Usually at 1/10th mile intervals that the planes use to calculate speeds. I-94 in western Michigan used to be a fun place. Planes would fly over picking out violators. They'd radio to a waiting fleet of marked units. And I do mean fleet. Sometimes 20 or more lined up on an entrance ramp, maybe 10 in each direction. First unit in line would take the next intercept. Once they finished, they'd go back and get at the end of the line. Just like cabs at airports back then. It was kind of funny to see 5 or 6 active traffic stops at a time within a mile or so of those staging ramps.
