Unfortunately it is a mixed bag in Western Europe. As I am above 30 and I look as I am now, adult, well off person, I most likely would not even have to have ID on me even when I am not in my native country. That said, when I was 20-something and had short haircut not having ID even in my native country could cause trouble. There are also places where Police is quite easy going like medium cities around 100k. Mostly they have enough work not to care for small infractions and are not overworked with amount of shitty people. In small cities it might be bad because they might not have anything to do so they would hunt you down on some silly stuff. In big cities it might be bad because they have so many shitty people to deal with so they just assume you are shithead as well and treat you like one by default. There are also places where rich people live and if you look like you don't belong, guess what, even if you look well off adult they might ask bunch of questions and Id if you don't look like you belong in the neighborhood.
