Exactly. When you look at a car, the engine isn't spending a majority, even a plurality of the energy removed form the fuel to overcome the fluid force of the air around the car. The engine is devoting most of the fuel to heat up metal near it. Then, when everything is heated properly, the engine can start providing torques to the drivetrain.
Automakers sneak the boat tail shape into their product through hatchbacks and Kamm-backs, and that's really all that needs to happen.
