If what Turn 10 kept saying in interview about incubating shaders and lighting in Autovista is true then thank god for Autovista. I also think that it's a nice peek at what next gen will hold for racing games.
Imagine racing in a cockpit close to an Autovista LOD in 1080p with motion blur, all while you see the sunset when emerging of Eau Rouge, your screen whipers trying to work they way through the pouring rain typical of the Ardennes region and the water sent by one of the 20+ smart AI populating the track.
