Brundle hasn't worn out "no doubt about it" quite so much this season.
Button has a bad case of the disease - I've even heard him say "for sure, not"!
Honestly, the use of "for sure" has obviously gone too far, no doubt about it.
For sure, not.
Psychologically speaken these guys live in an extremely competitive environment full of posing and impressing and not trying to show any weakness.
Whoever "for sures" frequently wants to cover up any weakness or insecurity that he really has. Then of course, the phrase has perpetuated itself, as it is handy for most characters in the paddock.
Compliments to Mark Webber, Timo Glock, Nico Rosberg and Heikki Kovalainen, who don´t need "for sures", they are the ones who are evidently really sure, so they don´t need to state it all the time.
