Many Europeans have no concept of time / distance in the US. When I mentioned that I can leave my home, drive at highway speeds 8 hours due east and have only crossed one state / provincial border, they are absolutely floored.
What really blows their mind is when I tell them that there a places here in Colorado in the National wilderness areas where one can travel to and be at least an hours drive away from another human being.
It explains why the first states are generally so small; European settlers had no idea how “unaggressive” their original land claims were.
