Faked Licence

In Mexico occasionally the police is checking you for no reason, once you hand them your paperwork, which for sure they will ask for, you will not get it back unless you pay for it. In case that would happen to me, and since I have no interest in buying my own driving license, I made up some copies that I keep and would hand to the cops if asked for it. So if things get ugly you could still leave them those and continue your journey with the originals in your pocket.
