5 Wheel-change Pit Stop by the Vodafone McLaren Mercedes Team - Lewis Hamilton at the 2012 Indian Grand Prix

Indian Grand Prix 2012 will go down in the records as "the race in which Vettel continues his path of complete domination in the closing races of the season." Coming off of a fantastic qualifying, Vettel lead from lights to flag, replicating his win in 2011. It's a tell-tale sign on where the teams are at when we look at the grid positions at the start of the race where Red Bull had front row locked, then McLaren, then Ferrari. Clearly Red Bull has continued to fine tune their race cars, also called the "Adrian Newey car" while other teams are merely catching up. It's hard to comprehend why McLaren and Ferrari with hefty financial backing have not been able to make their race cars more competitive. Who are the weakest links in these teams that's ruining the chances for the drivers and for the teams? Is it strategy (both in qualifying and in pit stop calls) or is it the technical challenges on the car itself?
