Probably not. Powerful, attractive cars are powerful and attractive because all of their components come together in a unique fashion. Attempting to create the perfect car through an algorithm that combines pieces from popular cars would be like trying to create the perfect human being by simply taking what polls say are the most attractive parts of highly attractive celebrities and combining them onto one face. The result would likely end up looking unappealing.
It's the same reason why attempts to make a formula for the "perfect movie" or "perfect video game" can never actually predict anything reliably. It takes more than just following a formula to ensure success.
You misunderstand my means. I'm not saying "just mash shit together," I'm saying "mash shit together and change it up," or more succinctly, "mimic natural selection." Car A mates with Car B, they mingle genes, but there's a random chance of a small mutation occurring, which may or may not harm the child car's ability to survive to pass along its genes. There are some fairly standard things, from what I've seen, that people call "attractive" in cars, traits they all share and, even if there weren't or if they're hard to nail down, there's only a certain number of things that will be appealing on a large scale; its why dumbass action movies with absolutely zero thought in them gross millions at the box office, and intriguing, thought-provoking cinema can flop on an epic scale.
If it can be expressed logically, it can be expressed to a machine. It may be difficult as all hell, but it is most certainly possible. Given enough time, anything can be made into a set of logical rules.
Dumbass action movies make a profit because they have mass market appeal. They're analogous to cheap and reliable Japanese cars, not Italian supercars. If anything, the supercars are the "intriguing, thought-provoking cinema": they have a specific niche that doesn't appeal to the majority of the population and may not necessarily be accessible to everyone and are thus reliant on luck and a strong target market to make an impact.
If you asked a computer to fake evolution to create the perfect car, it would probably make something that looks a lot like a Honda Civic instead of a Lamborghini Diablo.
It'd likely make a hybrid between the two. It seems like you're arguing that they wouldn't have any "love" in their creation, that there isn't a "human" touch, and would thus be rubbish. The thing is, you don't
know that: evolution made Don Vito, but evolution also made Karen Gillan. A cold, calculating, impersonal force can create beauty, and beauty makes one more successful in the theatre of evolution. If cars were people, then you'd see car porn starring the likes of the Dodge Challenger or a Rolls Royce Phantom, and only "niche" porn would star a Smart Car or VW Beetle.
When using attractiveness as one of the largest selection pressures, the results are more likely to be attractive the further you go down the line. Also, its not "fake" evolution, it'd be as real as we can make a simulacrum, especially if your RNG is cryptographically secure. Just set the rules, and let the dice do the rest. Its how we came to be, its how the Car to End All Cars could come to be, as well.
