The top tier of international single-seater motor racing — and a widely cited metaphor in founder circles for the compounding effect of 1% improvements across every subsystem. The F1 teams that win don't usually have a single breakthrough; they have a relentless operating cadence where aero, tyres, strategy, pit stops, and driver coaching each get 0.5% faster every week. A useful mental model for FeatureOS: the win isn't one feature, it's every surface getting sharper on a weekly cycle.
