but, its not rfactor, its LFS - with decent physics, real ffb feelings, can really push cars to their limits.
There are some rfactor tracks that I would love to be able to play on with proper LFS physics like mountain sprint, raceking's nurburgring and the brittish rally stage to name just a few. Yes there are some crappy tracks made for rfactor, but its up to the users to choose to download them, and the person who created it obviously enjoys racing on it so whats the problem.
As I say before I don't think we need car mods, there is plenty available to us for now (including the new VW when/if its released). Also this would probably get round the problem of updates breaking mods as most updates would be to the physics engine which is car based. Graphics may change but its not likely to be as frequent as the physics engine so would mean tracks would be less likely to be affected by any update patches and anyway whats to stop people from fixing the broken mods.
I also don't really see the problem of having 30gb of data either, we are not in the late 90s, you can pick up 500gb drives now for under £40.
