Given the situation he did exactly what I would hope from a determined individual, never give up!
I draw the line at a certain point, like ramming someone off the track etc but otherwise as the lead driver he has every right to set the pace when the only thing in the balance is his own result. With the constructors title tied up Mercedes had no right to dictate who wins the drivers title, it's called drivers title for a reason.
Sure keep them in line overall for a season, but at some stage you have to let them just fight. I feel sorry for a lot of people at Mercedes, it seems a small few at the top just want to make the whole team look bad.
So yeah, what Hamilton did wasn't the most team spirited, but I'd like to thing those without an agenda can understand, I'm sure Nico gets it, he probably even feels a bit better that he gets a WDC at the end of what turned out to be a bit of drama. But hey, no F1 for a few months now so the press have got to make up stories even more often for a while.
