Waiting for the day when someone drops a huge net from an overpass, or something.

Or mix milk & raw chicken let sit in the sun 4 weeks...put in large mouth plastic bottles and pour in vents below windshields of ice vehicles! They won't use those cars again!!

Spray paint “ICE” on them, that way if somebody owns them when they switch the plates back, they still have to paint over it or at least file a claim. Why make it easy for them?

That's the one!
