Vettel was rushing back to the pits before setting a laptime during the second qualifying segment in changeable conditions at Interlagos, as Ferrari sent him out on supersoft tyres but wanted him to come in to switch to softs.
Upon entering the pitlane Vettel was called into the weighbridge but the scales were coned off.
Vettel hit the cone immediately blocking the entry and gesticulated at officials to clear a path.
Keeping the car running, he edged forward while an official was standing directly in front of the car.
FIA technical delegate Jo Bauer said Vettel “refused to turn off the engine” and the car was pushed onto the scales but he left the engine running, which Bauer said “makes it difficult to get a stable result”.
