I really can't stand nascar, relatively ugly cars (Sorry, my real opinion) driving around full ovals.
Now I have no problems with tracks which are half oval, and half "real" track such as the 24 hours of Daytona (Which I loved) as it shows of the different capabilities of the cars.
Ferari had the speed on the oval, but the Audi smashed the Ferarri on the rest of the track with downforce.
