Ugh these people really make me mad. I've never understood why people get like that, just this full on elitest condescension. How could you possibly suggest that a realistic simulation doesn't help you learn driving techniques? I've applied plenty of what I've learned in gt and lfs to real life driving situation. Obviously you don't get all the physical feedback you do in a real vehicle, but that almost forces you to understand the physics of the vehicle more.
Actual FEEL aside I can say that lfs with my dfgt (I haven't had a chance to play gt5p with it yet) is a very accurate representation of actual driving, the feedback feels natural, the wheel will unwind itself realistically as you pull through corners, the vehicle behaves as you
would expect it to. Keeping in mind the differences between sim and reality there is plenty to learn that can be directly applied, wasn't some UK racing team using lfs to recruit drivers?
Its like these tools think that we believe were actually sitting in a car and its a 1:1 simulation. Granted I would rather be out practicing in a real car, but that doesn't mean there is a most accurate simulator to practice with.
