In the Collecting Cars podcast, Button talks about how busy he was and how emotional he was when his engineer told him about the team radio that he was a world champion.
The pressure was on
"I won 6 out of 7 races, but then it went downhill. Then I felt the pressure. Then I qualified 14th in Brazil, while Rubens Barrichello was on pole. I was so angry with myself, angry with the team because of the choice of tires," says Button.
He calmed down a bit in the evening. "I had a beer with my dad and thought: Tomorrow I'm going to win the championship. I have to win the championship. My dad said, 'That's right, kid. I was so determined then." That clearly helped, because Button did win the championship after finishing in fifth place.
