Powerslide

The year is 2020. After an environmental holocaust of devastating proportions, the population hovers slightly above the zero mark. The rich have fled underground, where they have formed corporate enclaves.

Above ground, the desolate cities and desert wastelands are inhabited by a feral population of freaks and survivors. With 98% of the population dead there's a lot of cars around just waiting to get driven into the ground. The ferals started the Powersliding competition, the corporates banned it.
