I think there were many times last year when we saw emotion, not that much maybe than in the past, but last year it was not fully emotionless.
Alonso and Massa, arguing about the Nürburgring incident. I liked it because it was honest, they spoke their mind, despite the cameras and live coverage.
Ron Dennis in Monza, he was crying after the race. After the espionage scandal, the tense atmosphere within the team, people calling for his retirement, the one-two on Ferrari's track was too much for him.
Alonso, many times. Shaking his fist in Indianapolis, stating after the Nürburgring race that he was fighting against the whole world, going straight against his own team in Hungary, was clearly 'alone' within the team from then on, and still missed the championship by just one point.
Lewis speaking his mind, too... "I have No.2 on my car, I'm the No.2 driver"
Even Kimi did show emotion, shouting "F***ing hell!!!!" into the team radio after the chequered flag in Brazil!
From previous years, Alonso saying F1 was not a sport anymore.
Jacques Villeneuve and his comments.
Juan Pablo Montoya and his comments.
The many middle finger showings we see from onboard cameras.
Sometimes listening to the team radio at the end of a race after a good finish, like Vettel in China last year when he was screaming and shouting for minutes.
The desperate attempts from some drivers to gain advantage, MS in Monaco '06 or Alonso, also in '06, free practice at the Hungaroring.
These guys are driven by emotion, you may not see it while watching them in the press conferences but it's not only their fault, if Senna, Mansell etc. raced now they would be pretty much the same I guess.
