Well you know it's just different kind of cars
Porsche - Mercedes - Aston - Alfa - lotus - Ferrari - Lamborghini - Nissan - Renault just a few of big brands here in Europe/Japan that does mass production (except lambo - Ferrari ) and sports car as well. I mean Renault for example with the Megane rs few years ago started beating supercar from left to right with a 35k euro car on the nurgburing.
As you well said its just a different way of engineering car. We build car to go fast on a track. That's what most our sports car are made for, from the one costing you 35k to the one that cost Half a milion.
Light, fast cars

Probably if gasoline would cost much less we would have seen different type of cars here as well
I have a love for both type of vehicles the American one and the others.
Probably you would feel great driving a under 2000lbs car with 250-300hp as much as I would love to drive a 7.0 v8 with 400+HP .... Supercharged of course because nothing like the whine of a damn supercharger
Oh and yes I do agree about how almost all your cars are affordable by almost anyone, something that here is not possible at all. Even mid sports car cost lots of money
