That's interesting. Any source? I live in the northeastern part of the United States and it's rare for me to see a speed limit above 65 mph.

120km/h looks like the typical global speed limit, but I haven't calculated it. It includes China, India, Brazil, several countries in the middle east and Africa.

Here in the Midwest we have several highways that are now 75.
