The Kers advantage on this track is supposedly insignificant, even without the wet conditions. If it rains today and tomorrow then Vettel has a good chance of hanging on to his title chances, and Id much rather see the championship being decided on the last race rather than this one
I fail to make the connection, what does KERS have to do with Vettel or Button seeing that neither has it? Or are you claiming that KERS is the only reason Vettel has not been winning the last several races?
Unless Vettel wins the next 3 races He does not deserve to be even mentioned as the possible WDC... Button has 6 wins, 3 times as much as anyone else, He is clearly the hands down WDC this year. Wins are real, points are arbitrary, some years a win is worth 9 points, some years 10, some years a point for 8th place, some years not.... it is all asinine... A WIN has always been a WIM (unless your teammate crashes on purpose to make it happen), and whoever has the most wins should be champion.
