I do keep my card with me in my wallet (after all thats why it comes in card fom)
The paper half i keep at home.
No; it is still in it's original plastic wallet albeit faded and falling apart. It's in a locked filing cabinet along with other ID related stuff.
I never leave the house without my Driving License - Used for age/ID verification mostly.
I was also surprised to hear in the other thread that some people don't carry it on them...

If you're young or look young then I can see why you will need to carry it for ID. Unfortunately I'm no longer asked to verify my age![]()
I definitely understand why you wouldn't carry it if you were old enough to not get asked - I think I'd still carry it nonetheless, otherwise I'd always forget to bring it when actually required. But my wallet is like my phone - I carry them both with me wherever I go. They're like an attachment to myself, and I feel naked without them
