I was referring to American culture, not human culture in general. North Korea, for example, has the largest sport stadium and their human displays at that stadium are hundreds of years ahead of American ones. But that's North Korea and the culture that is there. You can have fantastic stadium displays, but building a road and a car to go onto it is impossible.
