My theory is that the folks who complain about RBR's physics are at the ends of two extremes: 1) the newbie who doesn't have a wheel, or 2) the sim snob who can only tolerate the likes of GPL.
As someone who has played many racing games and sims, (from NFS5 to GPL, Papy's N4 and N2002-3, F1 2001-2 and its mods, LFS, the GTR press demo and so on), RBR's physics feel just right to me. They're just the right blend of fun and realism. There's a limit to be found, the tracks have plenty of variety and depth, and it's just a huge rush driving in such twisty, narrow, and dangerous conditions at such a fast pace. Much more intense than driving on a track, multiplayer situations excluded.
This is the problem w/ Starforce btw - the effect that that one word can bring to the table for some people
