Once you get the drifting down, the game becomes pretty easy. Still, the game is gorgeous and it plays well. I haven't played it online yet so I can't comment on that.
To drift, all you need to do is tap the brakes before going into the turn and then steer hard in the direction of the turn. You car should be perpindicular to the road at this point. From there, you can make adjustments to your angle. The drifting is fun and a major part of the game.
