Well I haven't noticed any of those either, ever. Its true I didn't look for it specifically, but anywhere outside US this would stick out at least a bit, especially for a space nut like me. And I also include all the travelling I ever done, on 6 continents, sometimes for months in a row when you mean tons of folks including US citizens. Neither I ever saw it in Geneva in Switzerland where I live, which is home to CERN folks, many UN/NGO folks, banker folks, or generally quite international folks. Maybe you keep seeing 2-3 people in your vicinity over and over?
