@Pelican You are right. I guess I didn’t put it well enough. For sure, Vettel is not the driver, who has made most DRS passes since the beginning of the 2011 season because quite often there is simply no one in front of him. But that doesn’t mean that the potential isn’t there. This is what James Allen recently wrote in his blog about Vettel’ s 2012 season:
He made up places from his grid slot on eight occasions, gaining a total of 22 places from his grid slot in races where he started behind pole. (Plus in Abu Dhabi he made up another 22 places after being forced to start from the pit lane).
So DRS has certainly helped Vettel a lot of times, while I don’t think that he’s been often passed by someone else with help of DRS. Last Sunday was rather an exception and I’m sure that Vettel’s ‘DRS balance’ is very positive.
What I wanted to say is that most drivers have much more reason to feel annoyed about DRS, particularly the likes of Force India and Caterham drivers, whose chances to defend relatively good positions are often destroyed by DRS. So I guess that their frustration must be bigger than Vettel’s, which makes me wonder what is the use of a gimmick that every driver hates.
