Yep, that's the "peach people coconut people theory", look it up. Most europeans are coconut people, education makes it so that you don't straight up talk to people like they're you're buddies, in German en French for instance there's the ''Sie'' or ''Vous'' form, which is a way to engage people you don't know with a mark of respect, and it means , in these cultures, distance.
The second step is to break the ice, some people will accept the initiative, some people will deny it, if they accept they open up and you'll get a genuine conversation, no shit chat talk, germans and french are generally ill at ease with shit chat by the way, it is seen as being fake.
In the US, showing respect is more like showing warmth, trying to make people feel at ease btw.
