TL;DR of the post, generated automatically.

OP shares Speedmaxxing, a free browser racer set on Dubai's Sheikh Zayed Road, built in plain Three.js with no engine and running on phones and desktop.

  • Replay director: The game keeps about 11 seconds of scene data sampled 30 times a second, then replays it through a drone camera on a Catmull-Rom path, with a raycast to stop it clipping through trucks and bridges. Players can download a 9:16 clip made entirely on their device.
  • Crash physics: Hitting a car turns it into a cannon-es body with mass by vehicle type. Friction and tyre grip are handled by hand, and nearby traffic becomes kinematic sensors so wrecks can start pile-ups.
  • The world: A hand-built road with the Burj Khalifa skyline, Metro line, bilingual signs and a day-to-night cycle, with procedural vehicles. The UI also works in Arabic, with right-to-left layout.

OP also mentions live two-player over Supabase realtime and a police drone that hunts you down, and asks for feedback on the replay and on how it runs on your device.
