Loz summed up the handling really well. It feels like the wheels are welded directly to the chassis with no suspension.
This picture summs up what was great about the old physics:
Power on full
Smoke billowing out
inertia making the suspension do an impression of a yacht.
In honesty, I feel the game would feel so, so much better if going around a corner you could feel the G force you were under. Also, whenever you go offroad the lack of suspension seems really strange, the car shouldn't bounce around as rigidly as it does, and it doesn't feel right. On top of this after a jump, teh way your car slams to the ground is just flatout wrong, as there should be absorbtion/rebound etc.
In short, the only thing I genuinely have issues with is the handling, and i'm allready learning to deal with how it feels, all in all:
I give it an 8
