Anecdotally, 40-ish years ago, one of my mom’s relatives came to visit from Poland. There are a whole lot of wild stories about that visit and from when my mom visited Poland around that same time that highlighted a lot of differences between life in the US and from behind the iron curtain at the time.

While he was here, her relative was amazed to see cars pulling off to the side to let emergency vehicles pass, that was apparently something totally new to him.
