I feel so bad for the Hummer marketing manager that funnelled their guerilla marketing budget into this turd. It reminds of a few licensed racing Dreamcast wonders that suffered from the same problems: bad physics, boring maps, redundant gameplay, car customization that made no difference whatsoever. Everybody knows that if you're going to make a game where you can only choose one car, it has to be red and there must be an ever-present blonde in it, duh guys! Um. Who's in the mood to hear magical sound shower? Go for it!
