This is an ongoing trap consisting of officers standing behind bushes in an apartment building’s parking lot. There are several cop motorcycles parked there, but they are well hidden from northbound traffic.
They identify their target in advance and then step into traffic to stop whatever vehicle they’re interested in. Most often they like to pull over Corvettes and the like; anything flashy or expensive is at risk.

Your Radar detector is not likely to pick them up. Maybe we can work something out in the future, just send your annual penalty check, so they don’t have to stand around so long!
