Schumi, Senna, Piqeut Snr and Peroni all great shouts for the retired/deceased. Piquet Jr on the other hand would total his car for his teammate. Whata guy! Utterly selfless.
Out of the current guys, got to say Button's the most likely. Turkey and Japan 2010 if I remember correctly are examples. Trying to take the win off Hamilton after they'd both been told to hold station, then being put back in his place. In Japan Hamilton was still partially in the running for the title and had a gearbox issue, Button could've stayed behind and not lost any positions but took the 4th (?) place for the sake of it.
Webber will if given half a chance from now on!
Least likely, Rosberg is obvious, Hamilton's too conscious about pleasing everyone, Raikkonen appears a straight forward and honest fellow from everything I've read about him. Quick Nick certainly wouldn't, and that may have been his downfall. Massa, of course. Grosjean's gotten out of Kimi's way a couple of times before.
I loved Sato's face.
