Unfortunately that is about all you are bringing to this discussion You are quite adept the copy-and-paste of partial bits of information but you seem to have little understanding of what they mean.
Good grief man...when was the last time you drive something beyond a motorized rollerskate!
Taking your impossible example to the extreme if we geared up a car to a 1:1 ratio just imagine the distance we could cover on a gallon of gas and the speed...wheee!!! My goodness that would demonstrate how efficient a pbuttenger car with a Otto Cycle (4 stroke) engine could be. But why stop at 1:1, lets go further... a .5:1, .05:1, why there is just no limit to how efficient and fast we can make our cars.
For the umpteenth time no it is not.
The very simple reason of why this is so is apparently beyond you. Just take you car, fill it up with cas, reset the average mpg to zero and embark of a 350 mile trip at 55mph. Repeat the same drive with a full tank of gas this time at your favorite 78mph. Use the speed control to be sure.
And report back the results.
