At 26, he is the youngest quadraple world champion but showed maturity beyond his age in his words even though there was childlike enthusiasm in his actions and gestures.
He knew that what he had chosen to do after winning the Indian Grand prix will not amuse the race stewards but he did it.
Instead of parking his car as the rules would suggest, he performed donuts with his RB09, named 'Hungry Heidi'. He then bowed, jumped on to his car and threw his gloves towards his fans, making for unprecedented scenes at any F1 Grand Prix.
He was expectedly reprimanded by the stewards and his team Red Bull was fined 25,000 euros. The German said it was a spontaneous outpouring of emotions.
"It is also a special place to win at and yeah, when my engineer called for the usual procedure - parc ferme, park the car - I said to myself I don't care, I go there, the crowd was great in the main grandstand and I'll have some fun there which I enjoyed a lot.
