No, I grew up there and lived there off and on for most of my life. If you want to see a place where people really ignore other people, look at California. Coldest people I ever met out there.
Sorry. I have travelled almost this entire country. I never got the feeling that NY'ers cared about anything but their own self. I never got invitations to spend the night like I did in Wichita, Amarillo, Owatonna, MN, and various other places while I was there on a job.
Driving in NY can be hell unless you get very aggressive which is not really conducive to friendliness. NY is just one big competitive world and outsiders are very rarely, unless they have something to offer in return, made to feel welcome.
