Misuse of "exponentially" is a pet peeve of mine, sorry.

Sorry to burst ur bubble man, but your looking at the wrong equation. For air resistance yes, it is a function of the square of your velocity (v^2) however, when we talk about gas mileage we should be more concerned with the power req'd to gain/maintain the objective velocity. To calculate the req'd force or power we look at the equation
Power = Force Drag * V supposing that
Force Drag = (1/2)*density fluid*(v^
3)*area*drag coefficient
and therefore the growth in power needed, which directly translates to gas mileage,
is in fact, exponential.
