Toy Cars on an Infinite Highway

A fleet of chunky die-cast toy cars racing down an endless rainbow highway that curves upward into cotton-candy clouds, low tracking camera skimming just above the asphalt with a 18mm fisheye lens, bright midday sun with crisp cast shadows and saturated primary colors, glossy plastic shaders with tiny imperfections and visible mold lines, speed lines and playful whoosh trails behind each vehicle, cheerful 3D animation style like a premium commercial, ending with all cars drifting in unison around a giant lollipop roundabout.
