We use the formal you much less.
Informal you is more common in other places
“The “you” we use here is neither formal nor informal, but a secret third thing.”
No but seriously, what did you mean to say? Germany make up roughly 8/10 German speakers, so “most of the German speaking world, except Germany” doesn’t really mean anything to me.




That doesn’t change anything?
You said you use the formal you more than Germans, but less than the “German speaking world”. It’s a bit weird to use that phrase to mean “any German speakers except Germans” I think, especially in the way you wrote it.
