Don't know why I find myself typing again, since it'll fall on deaf ears.. but anyway.
Dear Scawen, the problem has never been your adventurous mind that explores a myriad of paths in the development process, nor was it the fact that Scirocco hasn't been released back in 2008 (or that you're not a drivetrain & electronics engineer and cannot code a whole ESP on your own - although the pricks at VW could've given u more help than a Scirocco pamphlet..), problem isn't even the tire physics.
However, this is the problem: you haven't looked at the LFSW most used car/track graphs for a long time, you haven't looked at LFS Forum leagues that are springing up left and right (most of them new endurance leagues).. so you haven't realised that we would just like some new stuff to drive. It doesn't have to be real life track and cars, doesn't have to be anything you would need to pay a license for, most of LFS' imaginary tracks are GREAT, cars too.
So, why do I have to cry each year when 24 h of Le Mans rolls around? Why do I have to suffer through beurocrats trying to balance the GTR class for every new season, not understanding that there's little to do about a shit-to-drive FR layout race car with huge turbo lags other than slow the car that's nice to drive waay down? Why do we have only 4 tracks wide & fast enough for endurance multiclass racing (KY2-3, WE1, ASX)? Have you tried being lapped or lapping even decent drivers around SO4 and BL1 with a proper race car (in multiclass racing)? Cmon.
These are the pressing concernes that cause all the moaning and quitting. If Scirocco came out tomorrow, it wouldn't be driven any more than a FXO, maybe for the first month or even three. So, why lay all the delays on the poor car and the tire physics? Correct me if I'm wrong, but would a newly added car or track need to be completely re-done once the tire physics are updated? I'm not a coder, but I really doubt you'll be updating all the LFS cars every time tires are changed (like in patch Y).
Two more fast & wide tracks, one GTR class car (or at least fixing the two currently there) and something resembling a sports-prototype class and you wouldn't hear any bitching for at least 2 years, and I don't think it's and unrealistic timetable (releasing that amount of content with your workforce capacity in the timeframe since the last update was delayed).
