Build a fully playable mobile 3D racing game in the current project. Use the uploaded orange supercar image as the visual reference for the player's car. Create a lightweight 3D driving environment with a road, checkpoints, AI traffic, third-person camera, realistic car physics, touch steering, accelerator, brake and handbrake controls. Add realistic lighting, reflections, shadows, engine audio, collisions, race timer, start/restart buttons and a finish screen. Optimize everything for Android phones and prioritize smooth performance. Do not make a static mockup—implement the actual playable driving game in the project.
