Despite leading early, the 37-year-old finished the Nurburgring race even behind his Brawn teammate Jenson Button in sixth place, ranting that it had been a "good show from the team on how to lose a race" and that he didn't want to go to the debrief because "it will be all 'bla bla bla bla'".
Barrichello did however attend the debrief, but even after a shower as well he insisted he view is "quite the same" and warned that he might "quit at the end of the year".
He subsequently flew straight from Germany for a holiday in Florida, and on Tuesday announced on his Twitter feed: "It was a tough day yesterday … I was very upset … but I am over it."
Barrichello also vowed to not let the affair affect the remainder of his season, with many observers interpreting his outburst as a sign of resignation.
"I will fight until I have (no more) chances for the championship. I promise," Barrichello said.
