What team policy? This is just an artificial concept invented by team bosses so they can rationalize moving their drivers around like pawns on a chessboard.
Let's see, one driver per car, he starts and finishes in the same car. If you win the WDC, only your name (and not of your teammate) goes into the record books. Fans come out to cheer for their favorite driver, I never noticed any "Vettel and Webber" banners in the stands at Hockenheim. If memory serves me correct, there were a lot of Vettel signs, but none linking him to his teammate.
Yea, in endurance racing they have more than one driver per car, they take turns ... to me that is a team activity.
To me, this is a sport of individuals battling on the track. Yea, sure they can co-operate on some minor issues. But when a driver lays down and allows a win to pass him by, he has stopped being a Grand Prix driver, and become a pussy.
Almost every driver is a selfish, strongly motivated individual who believes he's that good, and drives to win. And that's what I want, individuals competing to the very end, giving their all and never giving up. Those qualities are in almost every great champion, from Senna to Prost, to Schumacher.
