Nico Rosberg verged on losing his temper on Tuesday when asked by French sports daily L'Equipe about his alarming race-to-win ratio.
In 2011, the German scored over 50 fewer points compared to his first season with Mercedes last year, and yet he has signed on for a new multi-year term.
He was asked if he is alarmed that, more than 100 Grands Prix in and at the age of 26, he could be heading for a long and winless career.
L'Equipe said Rosberg's answer was angry.
"All the statistics; it's a journalist's trick," he answered. "I'm not worried and I don't think about it.
"If (Jenson) Button had listened to you (journalists), he would have retired before being world champion.

"I have extended my contract with Mercedes because I feel that I can win with this team."
Rosberg concedes, however, that when he raced the silver W02 for the first time in Australia in March, he was "a little disappointed".
"In Melbourne we had great hopes," he admitted, "then we realised that we were not going to be able to do anything about Red Bull.
"Now, I feel pretty satisfied with the season, especially since I have finished once again ahead of my teammate (Michael Schumacher)," added Rosberg.
