Aerodynamic drag affect on fuel economy.

Aero drag is 4x greater at 70mph than 35mph. Let’s adjust the system (which looks at 100kph) to be more dynamic for vehicles that can’t run at 100kph. IE, they should have higher fuel economy because there is less of an aero-effect.

Actual table is is in your aerospace engineering book if you are not mistaken at the time of this writing... Probably could find something more car-centric online.
