rotf and so true.
One thing to point out. While the F1 team are using NKP with a far higher speed of physics integration, the F1 car in this version has different suspension geometry, diff, guessed downforce (Only had medium downforce data to work from) and any other bits of data changed that the team did not want to give out for the obvious reason.
So I would assume this has the character of an F1 car but does not really drive like the real one for the reasons above. The diff info alone could result in a complete change the character as F1 diffs are very complex.
