I think you missunderstod it It says rallypack yes, but it mostly, or from what we belive, would be rallycross contest. The word rally was most kikely used because they were working on tracks that had gravvel on it, aka rallycross tracks
From what I can remember, the rally pack was supposed to at least have one different rally-like (WRC) car and if possible some point-to-point stages. It was definitely NOT just a rallycross competition thingy, because we can already do that right now with the app Victor wrote some time ago.
No offence taken
But that`s at least how I understood it as, that it was more like beeing for rallycross useages. But again, the details were never clear, and never will, so it`s a dead end eighter way
We still have an Impreza like car for one of the default backgrounds in LFS. There was clearly some work done on it that we haven't seen. I know Eric has worked on some other things that have never been publically mentioned, but only the devs know to what extent.
