I wonder if this seemingly minor thing screwed someone over. Guy comes back to where car was, it's gone. He misses some important family event or can't pick his kid up. His insurance skyrockets, he's now broke and has no idea some greater good future person stole his truck.
I don't remember the specific instances in question, they may have compensated for the theft in some way but the knock on effects could still happen.
/tldr over thought it, move along
