Could you build this?
Partial Basic 3D scenes and prototype controls can be vibe-coded with Three.js, but a performant open-world driving game with realistic vehicle physics, traffic AI, and real-time multiplayer netcode requires deep game dev expertise.
What it would actually take: A playable open-world browser racer requires WebGL/WebGPU renderers (Three.js or Babylon.js) integrated with an optimized physics engine like Rapier or Cannon-es for suspension and drift modeling. The hard parts include level-of-detail (LOD) management and asset batching for 60fps mobile performance, alongside authoritative state synchronization and client prediction over WebSockets/WebRTC for multiplayer racing. This requires specialized knowledge in 3D game physics, graphics optimization, and multiplayer network architecture.
