I think when JB overtook Koby at Brazil 2009 was the best radio transmission followed closely when JB won in Instanbul 2009 and said over the radio that the team ahd built a monster of car - natural and appropriate to the occassion! I think Kimi was the most dramtaic though dont you?
I guess he refers to this one: "I think, when you go to qualifying, you pull your trousers down and you see what you have got." Sebastian Vettel, April 9, 2011
Yaaaaay... An emotional and sincere radio transmission at the end of the race. Now THAT's what I'm talking about. ;p Congrats to Vettel and Red Bull! The class of the field in 2011.
