It's much easier now with the Certificado de Registro, required for all residents who are here longer than 3 months. Of course, if a driver doesn't have a registro ...
but there again, if s/he doesn't have a registro
and they can demonstrate residency longer than 3 months, then the driver is in trouble with that too
They can ask for airline stubs, I believe, which wouldn't be available in my house anyway given my tendency to chuck out all non-essentials. Not worth it, it really isn't.
