I never carry my driving licence with me as it has my address on. If it gets nicked there's a reasonable chance that my keys will also get nicked and I'm not that keen on someone having my keys and address.
Having a relatively uncommon name and being a director of one/two companies means it's trivial to find my address from the name on any of my cards (literally googling "address <my name>" and it's the first link that google gives).
