Actually it just shows how ignorant you are, there's so much more to oval racing then just 'going in circles'. mistakes cost you more, you need to be consistant every lap, and hit the corners perfect, because small errors lead to 10th's or 100th's off laptime which obviously mean alot more in oval racing. And yeah, car setup is more important in oval racing, and also a HELL of a lot more advanced then road course racing, so drivers need to really know what the car is doing and also what changes to make and shit. There's also drivers in nascar who shouldn't be racing in it right now, but.. thats what money gets you.
