It allows them to keep higher speeds in the super speedways. The turning radius of a 'stock' car going 170mph on the flat ground is enormous, so to allow them to maintain those high speeds in a small track size, they bank the turns to allow gravity to help them maintain traction.
This isn't needed in open wheel sports because of the aerodynamic downforce that greatly exceeds the force of gravity when at speed.
