It's weird, I've driven a few different cars and measured the MPG in them, and that's what I'm finding too. 60mph seems like the sweet spot.

I wonder if they design specifically for that speed, as it's the speed on most highways in america (someone correct me if not true)

Anecdotally I was once told that vehicles are turned to optimize their fuel economy around the 55mph mark.
