In the Netherlands, it is very regional whether or not you use the polite form. In the capital region, it is not used, and use is a signifier you are from the countryside, if your accent wasn't enough. There are courses on how to get rid of your accent (or rather, get one of the capital region), and ceasing the employ of the polite form is featured.
I’m surprised to read this, inasmuch as when I briefly lived in Rotterdam (if “capital region” comprises it, too) some years ago, my local acquaintances coached me in where to use the formal, and where to use the informal, and the distinction seemed very much alive.
Thats funny because in Austria it’s the other way around. People in Vienna are used to being overpolite and will use the formal “Sie” abundantly, whereas on the countryside everyone is always almost “Du”. There is the saying: “Am Land sind alle per Du”.
It isn't difficult to see why. Vienna was an imperial capital, the Netherlands 'capital region' was ruled by (wealthy) capitalists. One group would be focused on courtesy, the other on efficiency, wouldn't they?
Naturally, both are ultimately evolved into appearance, not substance (because of courae this difference isnt substantial).
