I'm currently becoming quite addicted to Real Racing on the ipad
I don't really find car racing games to have much staying power with me, but in this you are racing real people but time-shifted - I think the server knows the basics and then models the car AI to match what times the other racers actually did by having them cock up corners or beat you out of turns or whatever. You're beating real, fallible humans when you win. It does also have a real-time multiplayer mode but I quickly got pissed off by that as the other drivers are dicks and will ram you off the road to win.
