Esteban Ocon led for 14 laps in São Paulo. Then came Sector 2, and the realization that holding off Verstappen in the wet was never really possible.
There's a moment on lap 41 where Esteban Ocon stops attacking into Turn 10. Not because his tyres are gone — they're the same Intermediates everyone's running. Not because he's given up. Because he's done the math in his head and realized that holding P1 for two more laps is the best he can hope for.
