Reminds me of an event when I was driving to work years ago. This was on a stretch of rural highway, a nice new highway that tempted one to hurry along.
It had a few overpasses. One day, I was warned by a co-worker whose husband was a deputy sheriff that I should keep a very particular eye on my speed for the next few days, and I'd see why, on my way in.
The local law enforcement entities (highway patrol and sheriff's office) had just about every patrol car in the jurisdiction parked on the uphill slope past the overpass. On the overpass was an officer with a radar gun, and overhead was the spotter airplane. The airplane radioed in about people who were speeding 3-4 miles before the speed trap, the officer on the bridge confirmed the speeders, and the rest of the officers were just peeling off the overpass and chasing them down. All the speeders who giggled to see the first speeder get tagged, then carried on their merry way, were stunned to discover there were enough officers there to catch them all.
And it went on day after day after day. I never got tired of watching people blow past me, then catching up with them in a long line of traffic stops.
