While riding in the car, I saw those signs by parking spaces which said that cars parked there that shouldn't be would be towed away and "impounded". I didn't know what this word meant, and thought it meant the car would be put in a big machine that would crush it (and you would then have to pay for the cost for the car to be destroyed).
