Nice idea, remind me battle system of Hammerfight)
The game need a bit polishing, it's quite hard to damage with this maneurability (and I understand, that new steering results in absolutely new maps, with new turns), and a bit visuals tweaks - sometimes it's quite hard to determine, where you can drive, and where you can't.
Still fun and pleasant, with very good visuals, Car lights make the visuals of the game)
