I'm all for the idea...but part of the problem is that LFS is going slow enough as it is.
There was a promised new patch that was suppose to have been released over a year ago and there's still no indication that it will be released anytime soon.
Not to mention that they are also working on another real life track: Rockingham, and that has no indication that it will be released in the future as well.
Bathurst will have to be a luxury unfortunately until the devs start to release content at a more regular (and quicker) pace. IMHO, LFS should focus more on what would make it a better sim. Such as damage, a (complete) aero model, break offs, engine damage, track temperature, dynamic wind system, rubber build up, fix buggy barriers, better hit detection.
Only when ALL of those listed above are completed will I start to push for more real life tracks. But for now, those still unfortunately remain a distant luxury. In fact, I'm not even hoping for LFS to improve as a race sim (beyond the promised tyre physics) anymore..which is very unfortunate imho
