I'm usually okay in racing games, as long as I can shoot the guy in front of me, so I'm cool with Mario Kart, JakX etc. It's when I can't shoot the person in front of me and when the controls are trying to be realistic where I start to fail because I can't stop myself from spinning out and ending up in a lake or whatever.
Though the idea of exploding the scenery as your weapon seems an interesting game mechanic, but I doubt I'd actually play the game. Good review though.
