FR-AI / ANALYSISWhy it is worth attention
It demonstrates a working deterministic race simulation with real 2026 F1 data, including tyre life, fuel burn, and driver commands, all running client-side with a live map and timing tower.
Who it is for
- F1 enthusiasts and sim racing fans
- Game developers prototyping race management systems
- Software engineers studying deterministic real-time simulations
- Students learning about motorsport strategy and simulation
Use cases
- Exploring race strategy (fuel, tyre, pace) in a realistic F1 2026 context
- Testing and debugging deterministic simulation logic
- Educational demonstration of real-time game loop and Web Worker integration
- Prototyping feature additions for a full race management game
Strengths
- Deterministic simulation with verifiable state hash and fixed seed for reproducibility
- Uses official 2026 driver and circuit data for authenticity
- Includes multiple simulation speeds (1× to 16×) and pause/resume controls
- Provides real-time visual feedback via PixiJS map and timing tower with car inspection
Considerations
- Deferred major features: no pit stops, tyre changes, energy deployment, weather, safety car, or qualifying
- Only Silverstone circuit and 2026 driver grid are implemented
- Commands are limited to Mercedes drivers and only Pace/Tyre Management strategies
- Prototype quality: not a complete game, intends to be a first engineering slice
README quick start
Project Pitwall
First playable engineering slice for a real-time open-wheel race management simulation. The prototype runs the current 2026 Formula 1 driver grid around Silverstone using a deterministic fixed-timestep simulation in a Web Worker.
Run
npm install
npm run dev
Open http://localhost:3000.
Controls
- The race starts automatically at 1×. Use the transport button in the top-right to pause or resume.
- Select 1×, 2×, 4×, 8×, or 16× simulation speed.
- Click a car marker or timing-tower row to inspect it.
- Select either Mercedes driver and issue Pace or Tyre Management commands from the strategy dock.
- Reset restores seed
20260712and the original grid.
Verification
npm run lint
npm run typecheck
npm test
npm run build

Current scope
Included: the 11-team/22-driver 2026 grid, Silverstone's 5.891 km Grand Prix layout and 52-lap race distance, continuously extrapolated curved-centreline movement, lap/position/gaps, tyre life and temperature, fuel burn, Pace and Tyre Management commands, PixiJS live map, timing tower, two player-car cards, fixed tick, speed controls, deterministic reset, and debug data.
Intentionally deferred: tyre-set changes and pit stops, 2026 energy deployment, active-aero rules beyond zone visualization, battle resolution, weather, safety car, qualifying, and team management. These are sequenced in F1_2026_GAME_DESIGN.md.
Data sources
- Driver names, teams, three-letter abbreviations, and numbers: Formula 1 official 2026 drivers, 2026 driver standings, and official 2026 driver numbers.
