I'm going to have to digress guys... Yes, the physics may be slightly more realistic, but even driving in Most Wanted or even Underground felt more natural than this. NFS IMO should be an arcade racer. There are too many games out there that are sims, or claiming to be sims, and most casual gamers simply can't be bothered with serious racing.
In trying to be more realistic however, EA (and whoever the developer is this time) have failed big time. Not only is it, like zubi said, neither here nor there, it doesn't even look right going round a corner. Take a look at this for example:
And this:

Notice how the rear wheels are sliding out so much, and yet no opposite lock is applied? This isn't power-oversteer of a RWD car, it's how cars behave under normal conditions, and it's simply ridiculous. Ok, while it doesn't look natural, it's perhaps slightly understandable in an M3. But on a Pagani Zonda R? Big wing, diffuser, slick tires, racing aerodynamics? And yet the rear still steps out like that? I'm sorry, but this is simply unacceptable in a game trying to sell itself as a realistic driving game. Sure it looks awesome, sure there's lots of cars, sure there's Spa and the Nurburgring, but if a racing game can't even get the driving aspect of it right, then that's sorely missing the point isn't it?
(And I know all this because I actually tried the damn thing today, both on the PS3 and Xbox.)
