There has been a lot of discussion about Vettel and just how good he is and rightly so. He is on course to win three WDC titles in a row, something only two other drivers have done in the history of F1. For me, several questions which will, unfortunately, never be answered are: a) Would either Hamilton or Alonso have achieved the same results if they had been in a Red Bull over the same period?b) How would Vettel have fared if he had been in a McLaren or Ferrari during this time?c) If Vettel had Hamilton or Alonso as a team mate, instead of Webber, would he have come out on top or even won the titles he has? With two top drivers taking points off each other, it makes it a lot easier for other teams to steal titles (see 2007). Of course we'll never know the answers to these questions and it is always the way in F1 that you rarely have the opportunity to see how two top drivers compare in the same car; 2007 was the last time this happened and we all know how that turned out. If anything, I would say the result was about right - both Hamilton and Alonso were as good as each other and the results reflected that. With regards to the first question, I would venture that both Hamilton and Alonso would probably have achieved as much as Vettel has and consequently Vettel would have been in a similar position to those two if he had been driving for McLaren or Ferrari during this time. As for the last question, I have no idea. I have no benchmark against which to judge Vettel, other than Webber, and I don't consider him to be a top tier driver. I suspect it may be similar to Hamilton and Alonso at McLaren in 2007.
