That being said, PGR4 is NOT a simulator, although a lot more realistic than any racer currently out there, the actual physics is indeed geared more towards stylish driving. (Going faster around corners by hand-braking around it is not generally associated with realism. ;)
Anyway, all in all, PGR4 is an absolutely beautiful experience if you are into racing sweet rides in their natural state. None of the silly customizing which has nothing to do with driving whatsoever, and which is completely redundant, as you never see the car while racing anyway.
