Holy Shit. This game is stunning. Wow. I've read so much about the visuals, but finally playing the game itself is flooring me right now. On top of all this, there's a great arcade/sim feel to the controls that strikes a sweet spot in difficulty. Reminds me of Rallisport Challenge 2 in that regard.
The motion blur is godly in this--and I hate motion blur generally. Man. Good stuff.
If you haven't already, try the Dam Busters event in the Startline tour.
