Did you notice the post about trackspeed above. This determines whether you keep moving or get stuck.
Once you've driven a sled with more than 200hp. or 300 hp. at wide open, and you are only moving 40 or 50 mph you will be hooked.Currently, there is only on manufacturer that can offer this kind of power (the other guys aren't even in the game).
