I would LOVE to see a huge-ass racetrack out in the desert planes somewhere, where's there's more flatland, but also a course that becomes a challenge with obstacles, like rock hills, tunnels, around hills, a quick swerve around a body of water, through that town where the Dusters are just to harass them ...
You get the picture.
And one with a defined Start and Finish line so we can have the "Cyrene Duster Speedway"
I can imagine ALL kinds of events there ... maybe even throw in a patch of PvP zone somewhere along the way to make it more interesting.
