It's why you need only 300-400hp in a "typical" sports car to hit 180mph, but to hit 250mph you need over 1000hp.
We don't notice air as having resistance really because we are accustomed to it, but it can be treated like any fluid. The faster you go the more you compress the air and the more it wants to act like a solid.
