In Tn I can remember a few instances one I was aquainted with, but didn't involve vehicles, A small businessman who did landscaping took cash from his bank and was to fly somewhere, to purchase supplies of some sort. They waylaid him at the airport and took his money. It took him quite a long time to get it back and in the meantime lost his business because of it.
Locally our LEOs caught a rug runner, thinking back roads safer. They took 30,000.00 that was in their possession. I believe in that case they went to prison.
We have special units at pull outs and pull arounds all over our Interstates looking for drugs.
On I40, west bound especially, they had Officers outside their jurisdictions and Highway Patrol, in fist fights over who was going to watch which stretches.
Lots of money was made and still is as I40 West sees a lot lot of drug trafficking. I75 and I24 too.
I vaugely remember an incident involving motorhomes but so long ago I don't remember details.
