I am very concerned, since it's one of the most obvious ways to judge how realistic a racing sim is.
Take F1C for example, the lap times the top sim drivers do are amazingly close to those real life F1 drivers do. Now with possibilities to add a real-life circuit into LFS, I am really curious to find out how it goes.
I doubt it though, judging by the behaviou of FO8, in which you could take some fast corners flat-out, the bumpy feeling and the sound of tyre scratching aren't quite right methinks.
We don't know the answer, so please feel free to discuss!
