Quote from Ndrew :

Heck, even a flat autocross dirt/mud area would be a blast on it's own like a few (even me) were suggested or asked before.
AU tramac -> AU dirt or even BL3 would do it. That would be megafun.

An gravel autocross with bumps and even some small hills would be great.　

A track editor within the boarders of autocross track would be cool. Then people could do what they want, within that space.

Along with a dedicated dirt oval car, (late model, sprint cars) this would be awesome.

guggyyyyyyyyyyy
