After over 4 years waiting for something to happen in LFS there's no surprise there aren't any proper public race servers. There are almost always over 30 races on Cargame server, which is mixed class. There are other servers running but they're usually empty (or with up to 5 racers), then bunch of drift servers and some practices going on.
There's no place to race casually. I'm not into 1 server, because there are much more players to just fit into one server. (I hope I understand the idea properly). My ideal online experience would be couple of race servers covering each class of cars with track rotation, so you can really choose what you want.
When I began in 2009 there was this GTR server with AS National track over and over again (I can't recall its name right now). Then it was replaced by AMG's version of the same track/car combination. But then, there was the GTR server with track rotation...almost always empty. I never understood this, why would anyone play the same trick with the same car for over 4 years and decline opportunity for something new.
Another thing which sucks is there's nowhere to race in the night. There's just no server. But I understand, even if there were servers in western/eastern parts of the world, it would too laggy to play. That's why we must develop FTL transfer
