Auto racing is an obsession in Anderson, Indiana. Amidst the closing of auto factories and resultant loss of jobs, residents continue to flock to the speedway every Friday night and drivers continue to pour their dwindling resources into patching up their Thundercars for the next week. As much a demolition derby as a race, this cacophony of screeching tires and crashing metal gives inhabitants of Anderson a chance to lose themselves for a couple of hours, channeling their hopes and frustrations into a wild weekly contest for Thundercar supremacy. Directed by Jon Alpert, Dirty Driving: Thundercars of Indiana examines the decline of rust-belt America through the story of a once-thriving town and its all-consuming passion for auto racing.
