Autopia is a race car track Disneyland attraction, in which patrons steer specially designed cars through an enclosed track. Versions of Autopia exist at Anaheim, California and Disneyland Paris in Marne-la-Vallée, France. There was also an Autopia at Hong Kong Disneyland on Lantau Island, Hong Kong before it closed on June 11, 2016. Other versions of the attraction can be found at the Magic Kingdom as the Tomorrowland Speedway and formerly at Tokyo Disneyland as the Grand Circuit Raceway. A previous generation of Disneyland's Autopia operated for over a decade at the Walt Disney Hometown Museum in Marceline, Missouri; one of the retired cars is now on display. The name Autopia is a portmanteau of the words "mobile uto." The term was later popularized in academic circles by British architecture critic Reyner Banham to describe Los Angeles in his 1971 book Los Angeles: The Architecture of Four Ecologies. Disneyland Autopia The Disneyland Autopia, in one form or another, is one of the few current attractions that opened with the park on July 17, 1955. When it opened, it represented the future of what would become America's multilane limited-access highways, which were still being developed. President Eisenhower had yet to sign the Interstate Highway legislation at the time Disneyland opened. Drivers can use the steering wheel along the track but the center rail will guide the cars along the track regardless of steering input. Drivers/children too short to depress the gas pedal are paired with taller individuals who can. Brakes are applied automatically when the driver releases the gas pedal. The cars generate a moderate level of exhaust from the Honda GX gasoline engines that propel the cars. In 2000, it was replaced with a much larger Autopia sponsored by Chevron with many cars were replaced with Dusty, Suzy, and Sparky, the queue was even given animated dioramas featuring the Chevron Cars. History Before the park opened, the cars were tested without the bumpers, and were almost completely destroyed by the test drivers. Bumpers were fitted around the vehicle, but there were still problems with collisions, as a guide rail had yet to be implemented on the ride. Eventually the vehicles were fitted with spring-loaded bumpers to discourage collisions. The first fleet of Autopia cars were dubbed "Mark I". Throughout Disneyland's first few years, Autopia went through a few fleets, as the cars took much abuse. Though basically the same look,
