I just saw a brand new Mercedes and it didn't have a special sign on both the front and back side saying "don't ride this if it isn't yours, not even when you really really like it". I have asked Mercedes-owners to put such a sign on their car to prefent me stealing it. Do I now have the right to take every Mercedes without that special sign?
