There's a new app in the iTunes Appstore called Reckless Racing. Do not get confused with Reckless Driving, an old Mac OS 9 game.
In Reckless Racing you can host your own levels with your own specifications and car permissions.
You can crash other cars and push them off the road in a very realistic way.
You can access to our server called: Dakar Trucks or Dakar Minis.
