It spawned two thoughts for me:-
1) Vettel clearly wants to win, clearly does do a lot of winning, and without doubt, the team are largely focused around him. Problem being, though, that at times, both the team, and him, require a compliant "2nd" driver. Both for the constructors championship, and for later on in the season when it will likely be much more necessary that the "2nd" driver makes way for the first. Compare and contrast this to Schumacher - perhaps in his early, brash years he would have done the same - and perhaps we should just see that for Vettel. Schumacher learned to be smarter and more savvy, though.
2) Brawn made a very good point over the radio to Rosberg - ie we are asking Hamilton to drive to a pace, like we (effectively) want you to - as did Webber - they can't realistically race the cars at nearing true pace, they have to do so at a managed pace, so that tyres won't lunch themselves. Point being, when a team-mate in front isn't driving as quickly as the following driver, it isn't necessarily because they can't go any faster, but moreso they are being told to manage their pace and drive to a certain lap time. It's very easy for the follwing driver to try and look smug and restrained that they could go faster - quelle-fecking-suprise, probably most of the field could go faster, the problem is, modern F1 isn't so much about driving as fast as possible or racing as such, any more. The "spectacle" is more important, so all the machinations (of note at this juncture, the tyres) mean races are more about managing the speed and energy pushed through them.
CART / champ-car started to go through that phase around the late 90s, when for many, strategy and fuel economy started to become more important than damned well going fast.
