Very much not the case in the German speaking countries (where i have lived since early 2005). For a time this was one of my top reasons to want to immigrate to Canada (I was already working remotely for a Canadian startup at the time).

But being considerate in New York usually looks like staying out of others' way. It might seem like unfriendliness to out-of-towners, but it's a (perhaps counter-intuitive) form of courtesy.
