I'm down to just my backup card in my MagSafe wallet. I'll occasionally keep my ID in there too but only if I know I'm going out to a place that needs to check a physical ID. If I could, I would do without the wallet completely.
A few years ago I was surprised that in some states it is illegal to go out in public without an ID in the event a cop stops you and asks for ID. Seems completely contrary to everything we were taught growing up.
I am not a lawyer, but I am fairly certain that that isn't true (if you're not driving).
Many states require that you identify yourself (presumably full name and DOB at a minimum) to an officer upon request, but I don't think that means you have to carry the physical card, just provide your identity (which can be done verbally).
