Lower weight- yes fror "town driven cars", not so much of a concern for Highway?

Better Aero- damn straight- I cant believe how much interior space the "ideal aero template" would provide, even if the Kamm element was "chopped"

Gearing and engines

issues there around maintaining the "acceptible rate of accelleration" desired by the public, and smaller engines. smaller lumps need shorter gears to keep levels up?

Could the adoption of an "Eco 5th" to ALL cars drop highway/A road consumption?
