The difference between Antonelli and Pérez is context. Pérez was a decade into his F1 career, driving for the dominant team, trying to defend a championship challenge. Antonelli is in his first full season, driving for a Mercedes team still finding its footing in the new regulations. But the pattern is identical: a driver fast enough to be in the fight but not composed enough to stay clean when it matters.
The five-second penalty at the line dropped him from fifth to sixth — the final insult after a race spent bleeding positions he should never have lost. Miami's track limits are notoriously tight at Turn 5 and Turn 11, the two corners where Antonelli kept running wide. Turn 5 is a slow-speed left-hander where you gain time by carrying momentum through the apex, but the white line is unforgiving. Turn 11 is flat-out in these cars, and the temptation to let the car drift wide on exit is enormous. Antonelli gave in to that temptation three times. At this level, once is careless. Three times is a problem.
