Plush freeway-cruising sedans are optimized for the comfort of the driver and passengers. 

Supercars are not, with few exceptions: The Acura NSX has a reputation for being compliant, and the McLaren 650S is easy to drive.

But the whole point of the supercar is to tuck you down in a low tub made of carbon fiber or magnesium, swaddle you in firm, bolstered, racing-derived seats, and scare the bejeezus out of you as soon as you put the pedal down.
