The fact is that when you drill down through the crap what is left is
that you need a certain amount of energy to push a car shaped car on
tyres on tarmac at a given speed, over a given distance, and that the
bigger battery you carry the heavier the car and the more energy it
takes....

It does not help that fashion is pushing cars away from nice streamlined
shapes into things with the aerodynamics of a brick.
