It's still an alpha to me so that is why the two 0s. As soon as I get all the objects I want in there it will become become 0.1. Then once all the bugs are fixed and tweaked it will work to 1.0. Glad you enjoy it!
This is a freakin' awesome track! When this thing is ready it'll be for sure one of the best ever submitted.
It'd be desirable that more tracks - or at least the important ones - would have such a crisp road surface...
