^This. The whole idea of the endurance racing prototype class is a class of cars designed and built exclusively and entirely to compete in endurance races---not to help market road cars (the GT class does that) and not to try to look "good" to some small subset of fans. The cars are supposed to be designed and built to be moving so fast it doesn't matter what they look like.
Why not design open-wheel single seaters to look like road cars too? If it is such a good idea? Because single-seaters are supposed to be pure race cars, designed and built only to race. Seems almost silly to expect IndyCars or F1 cars to look more like street cars.
Same situation with sports car prototypes---designed and built to race only. Appearance is not an issue at all.
Form follows function is a form of beauty that only some appreciate, but it is also irrelevant. It is liking designing a fighter aircraft and then compromising the combat effectiveness to make it “prettier.” It would get shot down … like the idea that pure racing cars should look like modified road cars should be.
