It gets even weirder because at least in same states it is ruled if a crime has an age component then once again you can't be forced to reveal ID (which would betray your age) and incriminate yourself even if driving. And then in some states you're required to answer questions unrelated to your identity like if you're carrying a weapon (unless you can't have weapons, in which case you'd be incriminating yourself and then again you don't have to answer).

Not legal advice.
