I tested it for about 5 - 6 hours last night and gotta say I'm impressed
Before people used to say LFS physics were close to real life - I used to think yeah there not bad, I can imagine driving like that. Now I drive and it really feels like I'm driving, I don't need imagination any more the emerssion has jumped up a whole bunch of notches for me - so for me its definately moving in the right direction.
I think it will make the racing experience much much more realistic - imagine now these changes along with dynamic racing line, live track (rubble, oil, etc), mechanical considerations extended to engine wear/heating, brakes wear heating, etc, etc dynamic weather temp/wet etc
