What this build simulates Continuous car movement, braking and acceleration, tyre wear and temperature, slipstream and dirty-air effects, passing lanes, pit entry, shared pit boxes and pit exit. Pace, car attributes and driver skill affect the same state used for timing.
Short-format assumptions 10 laps, seeded race weather scenarios with abstract wetness and forecasts, scaled tyre wear and fuel effect, estimated performance, illustrative pit-lane geometry, optional preset qualifying order and simplified overtaking. Two distinct dry compounds are required unless intermediates or wets have been used. Tyres fitted in a stop count when the car exits the pit lane. This fan format permits all three dry compounds and unlimited virtual tyre sets; event-specific allocation is not implemented.
Energy deployment, safety cars, penalties beyond the tyre rule, full session simulation, career management and highlight replays are future stages. This is an unofficial, unlicensed fan prototype; no official logos, car imagery or live data feeds.
Quick weekend Optional practice and Q1–Q3 build a grid before the race. Practice uses short, instantly resolved stints with fuel-adjusted pace, wear and imperfect balance feedback. Downforce and balance carry into qualifying and the race. Qualifying accounts for estimated traffic, release timing, track evolution and driver errors. Session windows follow the verified 2026 rules; the remaining mechanics are labelled game abstractions. Delegate either stage to keep the session short.
Race weather and rivals Rain changes water accumulation, the drying line, tyre grip, temperature and wear. Intermediate and wet crossover points depend on condition and wear; wet tyres overheat on a dry track. The track shade follows simulated water levels. Forecasts extrapolate noisy current observations over two minutes and can miss arrivals or clearances. They are original game estimates, not real weather feeds or calibrated probabilities. Rivals use the same public weather forecast and visible pit activity, with different reaction times and margins. They can make poor calls. Safety interventions, aquaplaning and severe-weather suspensions remain deferred.
Saving and recovery Pit plans default to manual calls; automatic calls must be explicitly enabled. Analysis records lap times and pit visits. Live rejoin and strategy numbers are estimates using current gaps and modelled tyre behaviour, not guarantees. Autosaves every five seconds of active play and when the app becomes hidden; returning starts paused. The previous save is retained for recovery. Browser storage can be cleared or unavailable. Export a JSON backup for durable recovery. New exports use save version 2; older version-1 races migrate as dry races. Other unsupported versions are rejected; keep the original export.
Data and provenance 2026 roster verified 17 October 2026 against Formula 1. Names and team pairings are facts. Driver attributes, wet ability and car ratings are provisional estimates, separate from the engine. Monza length is official; community centreline data are not a survey of the 2026 circuit.
