Like the parking lot I would like to see a dirt field. A big square of dirt where you could have fun. With the parking lot people have created mini ovals for uf1 banger racing and is also used for autox.
With a dirtfield people could create dirtovals, rally cross tracks, destruction derby tracks, banger racing tracks etc.

search is a wonderful thing

But it must mean theres a demand for it
