I couldn't possibly feel more sad for people who can't let themselves appreciate how great these car physics are - is it perfect? No. Is it obviously more nuanced AND exciting than GTA IV's? Of course. It's less showy in its physics, but there's plenty of great and diverse driving mechanics happening under the hood throughout. A huge step forward from IV (which was a huge step forward itself), even if they still haven't nailed bike handling. The early bitching seemed dramatic, and having actually played the game all day, the whining is clearly even more baseless than I assumed it was. You want to live in the past? Your loss.
There simply isn't any nuance. I am enjoying the game but the driving isn't that great. I wish they met somewhere in the middle between this and 4. Or they had an option like Mafia 2 had. I play the on foot parts with free aim on and I am having a blast.
