The "driving experience" is good. There were/are a few things I didn't like, I felt car to car collisions were particularly weakly done, and (for me) there was a slight vagueness to the FFB, despite the framerate being good. Damage model is little better than LFS, you can still drive around with a car that is actually completely killed. The cars do behave really well, though. And of course the tracks are great, really well done, 100% accurate etc etc (not that you'd notice in most cases). They've also sharpened things up on the interface side now. Previously selecting a car and track was something you had to plan your day around (relatively), now it's much better.
They still persist with their "sign up for a race at Xpm" system rather than the conventional "join a server" system. I don't like it, you can go online with a beginner license and have to wait up to an hour for a race, and there may be nobody else signed up for it by that time either, it's a chance you have to take. It needs large numbers immediately, it's not easy for a tiny number of individuals to "hang out" and have fun in the game like you can with LFS and all the others. I would think it might be its downfall, except after committing the cash you'll persevere just to get value, and that might get enough people into it. They're offering all the extra content to testers for free just to get the user base up as high as possible. A smart thing to do.
I wasn't sold. If it was cheap I'd have it on my hdd and then if it was easier to use I'd race it frequently. It isn't, but I'm sure plenty of very serious people will get a lot of joy out of it, because beneath it all it really is very good.
