Air Wheel

Hold your hands up as if they were on a rim. The line between your palms is the wheel — tilt it and the car turns. Close your fists to accelerate, open them to let go and brake.

Hand tracking runs on-device with MediaPipe — the video never leaves your machine, and nothing is uploaded or recorded. Engine sound is synthesised in the browser, no audio files. Switch steering with M, camera with V, cars with G.
