Basically, you race against your opponent on the other side on a straightaway - just like Street Racer. Except it looks like you and your opponent are evenly matched playing 2 unmarked Checker Cabs trying to avoid what looks like smudges of Donkey Turd in the road. AS for why it's called "Deformable" - I dunno. Maybe it's because the car deforms when it crashes, but I'd like to understand why donkey turds crash cars? I can see why slamming into the wall in this looney drag race at the Cab Depot, but is my cabbie having too much diarrhea? Did his colleague fall prank to some laxitive laced vindaloo and that's his own poop on the track?
