Almost all of his DNF’s are driving error rather than mechanical failure
That sounded a bit wrong so I had to investigate:
China 2007 – Team left him out too long against the wishes of Bridgestone. He might as well have been driving on grease into that pit-lane.
Canada 2008 – Own fault
Belgium 2009 – Hit by Alguesuari
Abu Dhabi 2009 – Brake failure
Spain 2010 – Wheel rim failure
Hungary 2010 – Mechanical failure
Italy 2010 – Own fault
Singapore 2010 – Racing incident
So that’s at most 3 or 2 out of 8. Not sure how that’s most!
Anyway, the topic at hand. We always have to be wary of stats but your ones (amazing job by the way, thanks) offer a pretty good basis for comparison. damonsmedley hit the nail on the head, conversion is a weaker point for Vettel than Hamilton, which is strange considering all of his wins have come from starting on pole, apart from Malaysia where Webber mistakenly let him 1st into Turn 1 and picking up the pieces of Hamilton’s retirement in Abu Dhabi. Of course most drivers’ wins come from the same situation but Vettel has yet to win by passing for the lead.
I would say Vettel is good at winning when he’s on it that weekend, whereas Hamilton has the added knack of being able to come from behind. Both need to work a lot on strategy and measured moves, Vettel more so in the latter case.
