Why is there so many variations of f1 cars/planes/rockets? Wouldn't a 'perfectly' aerodynamic shape exist?

In the sense that out of all the permutations you could design something, surely there is just one particular way which would have the perfect shapes to create the right lift/drag/aerodynamics where it is needed?

There's an old credence used by engineers to describe these questions.  Think of finding the "perfect" design for anything as finding the perfect spouse.  Science would dictate, with a given amount of variables, that one could find the theoretical perfect spouse.  A man/woman that perfectly satisfies every one of our hopes, dreams, and desires.

The fact of the matter is, nobody has the time, money, or knowledge (or a combination thereof) to pursue the matter.  So what we do is use the information at hand, along with some cost-effective research, to determine the best design that we can reasonably accomplish with the resources available to us.

Science would dictate that there is a perfect solution to everything. Unfortunately, the perfect solution is never attainable, and that's why you need engineers.
