There's no doubt the games are getting closer to the real thing, but they always seem to be faster than real life, maybe it's because the game generally uses ideal conditions for the track temp, air temp ect.
As to the feel of the game v car I agree with what they say, although the game does very well creating the illusion of feedback, (even without a force feed back wheel) you will always be that half second behind in reacting to spins etc.
In the game you are relying on visual clues rather than real life seat of the pants feed back. In a real car you can feel the grip starting to give and react. Rather than seeing it go and reacting. However with practice you get to know the limits of the in game car and can set the cars attitude to counter it or negate it, as it's always going to be the same conditions in the game. I find that in the games you tend to drive more on the throttle than you do in real life.
In real life track conditions can change quite a bit with track temp, air temp during a race, not to mention dirt and gravel dragged on to the track makes it a much less consistent environment.
Over all as good as the games are they will never substitute for real life, unless someone builds a holo deck :D
