Street racing is typically an unsanctioned and illegal form of auto racing that occurs on a public road. Racing in the streets is considered an ancient hazard, as horse racing occurred on streets for centuries, and street racing in automobiles is likely as old as the automobile itself. It became especially prevalent during the heyday of hot rodding (1960s), muscle cars, Japanese imports (1990s) and sports cars (2000s). Since then, it continues to be both popular and hazardous, with deaths of bystanders, passengers, and drivers occurring every year. In the United States, modern street racing traces its roots back to Woodward Avenue, Michigan, in the 1960s when the three main Detroit-based American car companies were producing high-powered performance cars. Since a private racing venue was not always available, street races would be held illegally on public roads.

Megalopolis Expressway Trial is the original title of a series of six Japanese films, about illegal highway racing in the Shuto Expressway, released between 1988 and 1996. An English subtitled version of the film series was released on DVD in North America in 2004 due to commercial success of popular Hollywood films like The Fast and The Furious. A 4-disc re-release of the 2004 edition was made available in 2007, it was renamed Tokyo Speedway: The Complete Collection. Though also available in Hong Kong, the DVD edition was not released in Japan since the series is still banned and the last episode unreleased yet.
