americans can't design good race tracks, just look at their big race tracks, they are all large ovals or they have lots of long wide curves.
Do you even have a clue as to what your speaking on? I used to go to the USGP every year when it was run at Watkins Glen. We have some of the best road courses in the world here. Watkins Glen and Mid Ohio being two of them. Either of these would be a vast improvement over Indy.

Mid Ohio



Watkins Glen



This is the short course that NASCAR runs. There is also a 3.4 mile course that F-1 used.
