I am from a country with national ID cards and yes people are required to carry it on themselves at all time if they are outside.
It's mostly used to check your identity if the police stops you while driving, which is a little annoying because surely they could just check that electronically, but it's probably a legacy system. You also use it to verify your age when buying alcohol because driving license is not a valid form of ID.
It's not really a problem, I have mine in my wallet and never take it out, it's been sitting there for years. You can only really get in trouble if you don't have it while driving, and in that case I probably won't have my driving license either because it's in my wallet as well.

... while in other contries there is an ongoing discussion about whether it is against the Constitution to (begin to) require to show an ID when voting!
