How on earth can these people justify making this entire game, spending all of this "extra" time designing a more advanced version of the Redbull X and not make A SINGLE race that it is eligible for or even allow you to create a custom race in single player where you can determine the level of the AI drivers (in different cars)? I am thoroughly pissed off with these designers and the only thing that might bring me back to the game is if they fix this inexcusable oversight with the next update! Please reply if you agree... I know many people who play the game simply to attain and "RACE WITH" the Redbull X car (the ultimate driving machine)
