I've been building a test track for Vdrift for a while. It's far from finished, but it's already drivable. It's got a parkinglot area and a dragstrip.
I wanted to show the progress so you can download a preview from: http://www.kcid.nl/vdrift/parkinglot.zip
The blender file is in the art repository.
It's the first original Vdrift track so no conversion from another game.
