Thanks for your reply Stian, and this is just an 'academic' discussion for me as well, mainly cause I really would love to try rally racing someday but a simulator may be as close as i can get to the real thing.
I totally agree that GT4 shouldnt dub itself the "real driving simulator" and its a little hypocritical to do so. I dont know this for a fact but i heard that Kaz himself was bad mouthing Enthusia because its so realistic, and hence so difficult. He accused Konami of forgetting its 'a game' because they made it so hard to control. Again, i havnt read the exact statement, so dont flame me flamers.
By the way, have you played Enthusia or GTR? Ive heard alot of people say the driving physics are both more realistic than GT4. Also, have you ever done any real life rallying or circuit racing, just out of curiosity?
To the guys saying you can do donuts relatively easy in gt4. Im really not sure what your talking about, ive not gotten the super high power cars in gt4 yet but ive tried doing donuts in cars with like up to 430 hp. Maybe your confusing the odd slow circle which takes place when you spin the rear wheels with an actual donut which is where the front wheels barely move and the rear wheels do circles around them while they're not moving. Ive never heard anyone say its possible to do donuts in GT4 so im just asking, not suggesting you dont know what your talking about. Know of any links to vids? Oh, and yah i have all assists off.
