Quote from Ikaponthus :

What this video shows is that a professional racing driver is completely unable to drive even a tiny little, low-powered hatchback effectively with an R/C remote.

Actually this video show nothing that confirm your point, because he isn't driving from the inside of the car (try with a wheel to drive the uf1 in spectator view, I guess it won't be much better).

Otherwise I agree that those racing game, such as gt5p and forza, are not simulations, and I don't thing they are currently trying to be one.
Since this is not the gamepad that forbid a racing game to be a simulation ( you can perfectly drive on lfs or rfactor with it) , i think the reason that those games are so far from pc simulations is that devellopers want to hit a particular public. The public who wants to play a "simulation" without practising 3 hours before being able to make a good lap, those who want to play fast and enjoy it the way it is (and they are a lot more than us). Look Forza 2: most of the races are 6-7 laps long. The endurance races are 50 minutes long, it's ridiculous .

It's also possible to draft.

Yup, it is certainely draft or taking a shortcut (drive on the grass for exemple, which can sometimes help you to make a better time, but then the replay couldn't be sent on lfsworld)
