The matchmaking on Ridge Racer is still not working apparently. Bugbear suggested a patch on their twitter feed way back at the beginning of April but it's all gone very quiet. Anymore than 4 players in the 8 player lobbies and it all starts to go Pete Tong.
I was kinda impressed with the Ridge Racer demo. I liked the destruction and the graphics were pretty good. The car's handled like tanks though, and as soon as you dare touch that drift button it's like the road has turned to ice and your wheel's are covered
