I've just read the new and the report, I feel good they are working on something hard, but it is quite not a "progress report", since the mentioned investigation program might have been coded for more than a year already.
We can imagine that this program finished to bring conclusions to the devs about the real tire physics, but there is not any mention of progress of the implementation of the adapted tire physics code into the game. We just know that it is a hard task, and I fear that this real-time-in-game code will be near impossible to accomplish for the devs if I take in account their high expectations they showed us these last two years.
About the delayed release of the new track, it doesn't really matter for my personally, but I think that telling "we decided to wait for the updated tyres because these things from the real world will be best experienced with the most realistic physics system." is ridiculous.
OK for the Scirocco, I would be glad if its release is canceled for ever, but for the track?! What is the connection between new tire physics and the track? why the first is needed for the second? What the devs are afraid of? That we pick up a specimen of one of the realistic cars of the game, a FBM or the BF1, go to the real track, get lap times and assassinate the devs because LFS would not be able to reproduce these real lap times in the current state of the tire physics? :uglyhamme
