The way all the cars feel are completely unique, and very close to reality. You can feel the weight of a Lamborghini, and you can feel the differences in shifting gears and precision between all cars. All of that is pure perfection. The graphics and sound is great too.
What I subtract two points for is the racing mechanics. You'll be in first place with clear skies, and all of a sudden the whole flock is right on your bum. When I raced the off-road Titan, I saw the whole bunch of NPCs (maybe 10 of them) crash into a big house and they sat there just waiting to respawn at the previous checkpoint. So I passed them, and moved up to first place. Keep in mind that the first 4-5 seconds I'm in first place, they're just sitting there doing nothing and then they have to accelerate up to the same speed I have. In reality there would be absolutely no comeback for them, but of course after just 15-20 seconds I see the whole flock again behind me and they even passed me easily. Just the most retarded game mechanics I've ever seen in a racing game.
