Driving is like in the past GTA's. It's dumbed down and limited, but actually feels "fun" and responsive. Although Rockstar gone way too far to satisfy GTA IV driving haters.
In IV and especially EFLC handling was perfect for bigger trucks, good for SUV's, average for sedans etc, but awful for sports cars. Weight was great, damage was perfect. Overall was fine, but still far from perfect.
In V every car is f*cked up, besides sports and super ones which are ok. There's no weight in cars and they are too tough to damage. If you add Armor they are like tanks. ehh
Something in between those two would be perfect I guess....
