The ride journeyed through a Nature's Wonderland-like cavern filled with stalactites and stalagmites and a car wash filled with spinning bristle brushes, blowing air dryers and squirting water jets.
Concept art of Road Trip USA hinted at elements that would end up in the massive Ornament Valley rockwork that will dominate Cars Land, including the distinctive Cadillac Ridge and the jutting Gas Cap butte.
A second version of Road Trip USA added a Disney character overlay called Goofy About Road Trips, based on the 1995 "A Goofy Movie" about a cross-country road trip by the anthropomorphic dog. The attraction took riders on a journey with the absentminded Goofy where things went awry and mayhem ensued.
A third version of Road Trip USA dubbed Sally's Road Rally took visitors through familiar locations in Radiator Springs and into the world of the "Cars" characters. Those plans ultimately inspired the development of downtown Radiator Springs as the centerpiece of Cars Land.
Ultimately, many of the ideas developed for Road Trip USA and its descendants showed up in Radiator Springs Racers, an indoor-outdoor attraction combining a leisurely dark ride prelude with a dueling side-by-side race-car finale. Similarly, the Route 66 souvenir shop morphed into the Radiator Springs Curio Shop.
Originally conceived as a dark ride, Junkyard Jamboree would have taken visitors through an auto salvage yard where old junkers came to life after dark and played music. Animatronic characters built from random car parts would transform into musicians in a band called Johnny V8 and the Rev Tones.
Imagineers dropped the ride concept but kept the name, with Mater's Junkyard Jamboree reimagined for Cars Land as a cross between a traditional teacup ride and classic whip ride.
The final concept drawing of Carland included many elements that would eventually migrate to Cars Land, with an expansive Radiator Springs Racers ride dominating the horizon and an embryonic version of Luigi's Flying Tires levitating bumper cars taking shape.
