Interlagos is one of the calendar's genuine order-shufflers. The lap is short, the field is compressed, and the uphill run to the line combined with the Senna S braking zone makes overtaking realistic, so a poor grid slot is far from fatal. Weather is the dominant variable: Sao Paulo storms arrive fast and have decided a long list of races here. The sustained left-hand loading punishes the right-side tyres and can force strategies apart. Safety cars are reasonably common given the bumps and the close racing. Favour drivers who are strong in the wet and confident in traffic over those who rely on clean-air pace and track position.
