It's for people who have time and money to fuck with people.
I remember a comedy routine from the 90s. I can't remember the comic, but this was his bit:
"If you got nothing to do for the next, oh, 3 to 6 months, do what I do when you get pulled over for speeding. Pull over and when he comes to the window, roll it down slowly and say this:
"Good evening, officer. Is there a proble-there's nothing in the trunk! No guns. No drugs. No... dead... bodies...
"You want to look? I've got a key! We can go back there together!"
