Hamilton, with one foot out the door, telling his engineers that they should retire his car after he sustained a puncture (a puncture, for Christ's sake!) was only slightly less shameful than the Sky commentators attempting to pass this off as a noble, engine-saving gesture rather than what it was - a butthurt former World Champion trailing his wounded ego back to the pits, while exerting more drag on his team than any aerodynamic issues they might be battling. As soon as he got his head down he was fine. However, the glib words of gratitude that he occasionally throws in the direction of the backroom multitudes who provide him with a car in which to race, are not reflected in his self-absorbed bearing. If you put Alonso or Vettel in the Merc they would probably set up the car better and maybe even drive it as well.
Mercedes, for all the overflowing promise of their mercurial rookie driver, and for all the positive steps they have taken to undo their lowrider bounce, are still at a point where they are reliant on DNFs and spergery from the Red Bulls and the Ferraris for podiums. I foresee a frustrating season bogged down in the dirty air of their rivals.
