The thing you are missing is that some of us do have real driving experience in very high performance machinery. One also needn't drive the exact cars we see in the game to draw the conclusion that PD has some very glaring physics faults. For the most part the cars of similar drivetrain layouts will drive pretty similar to each other unless they have very quirky weight bias. Sure, the NSX will drive differently than the 330P4 but we are also talking about a 30 year gap in technology minimum. The biggest difference would be the tires, does the 330P4 have era correct tires on it or current spec tires? I dont know if PD makes that info available to us which makes it difficult to compare these cars in real life even if someone drove both of them. The bottom line is that thru the different physics models it was pretty easy to find some very unrealistic aspects of the cars in both the handling and the speed at which the cars could be lapped while using some rather unrealistic input methods. It's hard to call a game a "real driving simulator" with these issues and even though I have not tried any of the other driving games on PS4 yet it doesnt surprise me that PD may be far behind some other studios in handling physics.
