I'm the UK England and Wales you can't be required to carry ID at all.
If the police ask you for them, you have 7 days to present them at a police station.
(Edit: really not sure it extends to Scotland where such laws often vary, and pretty sure it doesn't apply to NI, where they vary even more, especially on driving/licensing, so UK was inaccurate)
AFAIK the ID law is a consequence of a centuries-old right that you cannot be required to identify yourself if you're doing nothing wrong, and then even if you did do something wrong, you still can't be required to have brought ID with you since it's likely you didn't set out knowing you'd be doing that today.
But the surveillance/camera thing is recent, when rights of ordinary people apparently are less fashionable.
Technically they can't demand ID here either, unless you're operating a motor vehicle which requires a licence. It's different on paper because theoretically driving is a choice (and actually was decades ago), but guess which kind of vehicle our entire country is built around?
I read that in Alabama (or maybe Mississippi, I can’t recall) you can drink alcohol while driving. You just can’t be above the blood alcohol concentration limit.
Louisiana had famously (or infamously) lax liquor laws for decades, so maybe that‘s what you’re thinking of. Shit like drive-thru daiquiri stores, where as long as they don’t put the straw in the cup it’s not considered an “open” container. So they can just hand you a cup full of liquor, and the straw separately.
It’s also a large part of why New Orleans developed a reputation as a party town; Louisiana kept their drinking age at 18 while every other state was at 21, so all the college freshmen/sophomores would go to Louisiana during spring break because they could drink.
