Driving model in GT5 feels "right," to me as far as driving in real-life is concerned. My issues with GT are the bad grind for cars (some of which aren't in arcade mode so you have to do that for them), the license tests (that GT5 thankfully ignored when they were required for career mode in GT1-4), and circuits. Real-life tracks just aren't as amazing to race on as some arcade racer circuits. Maybe it's the speed difference, I dunno. But point to point or rally races are better uses for simulator physics than circuits.
