Clearly he was frustrated from Saturday, fastest in Q1 and 2, then he leaves in late in Q3, then the penalty before the race even began, then Shumacher giving him damage then over taking him. The the awful pit stop. Of course he's gonna get pissed off, all that bad luck all on 1 weekend . Maybe whoever is in charge shouldn't have released him for an interview.
He's said this anyway.
“I've just been to the stewards to make peace,” he said.
"It was a bit of a joke, which wasn't funny at the time. I made them
aware that when emotions are high - and it's very intense at the end of
those kind of races - you don't always say the right thing.
“We've made our peace. They accepted my explanation, they understood. We all
shook hands afterwards. They said it was a tough weekend, let's move on, and
they all wished me well for the season."
