Not one of those cars on others garage-list would be for ‘general driving’, those are cars ranging from $300,000 to $1M that are geared towards track use. (Which is others commented on specific for tracking). Anyone purchasing a high-end performance Porsche, McLaren, has full intent to track those cars in most situations. These aren’t leisurely drivers, but even so, if someone doesn’t track their performance car, it doesn’t make it ‘a waste of time’. Some of us are collectors (Jay Leno would be a prime example in many different performance segments), some of us do track our cars, We all have preferences of what we Drive and how we choose to Drive it. It’s Unnecessary to label what they choose regardless, And doesn’t make it a waste time either, not when the whole intent is enjoy the car for what is.
I guess I’m confused, you claim that you know exactly ‘what you’re talking about’, but you don’t understand the aerodynamics of a car high end performance car? Or the purpose of a spoiler? As in, You’re questioning their existence to begin with, which I’m not entirely sure you do know what you’re talking about. I’m not questioning your mechanic/Structural background, but in terms of performance, Your comments above kind of indicate otherwise.
