Lewis Hamilton reckons he must have done something wrong in Brazil to incur a drive-through but has no idea what exactly.
Racing with Valtteri Bottas, the Mercedes driver collided with the Williams man down the back straight towards Descida de Lago.
The impact resulted in a blow rear left and a retirement for Bottas while Hamilton also suffered as his rear right was punctured.
However, the Brit's woes were not over as the stewards deemed him responsible, slapping him with a drive-through penalty.
Hamilton recovered to finish ninth.
"It was drive-through, I don't really know what happened," he told the BBC. "I need to see it again.
"I just don't know what happened, I went to the right and we touched, I obviously did something wrong.
"A podium was achievable which is why it was so disappointing. I am just glad it's over."
