Oddly specific, i know.
But this is still very interesting to me.
As a Euroepan, as soon as we cross borders, even if everything else stays the same, the look of the motorways, the signs, and the plates on the cars tell you are somewhere else immediately.
But there is no such thing if you leave the US and enter Canada, at least it seems that way to me. In Mexico, it appears to be the same as well.
