I don't really think that driving well, in a single GP gives you the right to say that "you are worthy of the championship".
indeed, looks at the stats
Wins
Webber - 4
Alonso - 3
Hamilton - 3
Button - 1
Poles
Vettel - 7
Webber - 5
LH + FA - 1
Button - 0
Fastest Laps
Vettel, Alonso and Hamilton - 3
Button - 1
Podiums
Webber, Hamilton - 7
Vettel, Alonso, Button - 6
So yeah, world champ material there.
At the end of the day Hamilton has been far more consistent and in the early part of the season seemed intent on breaking the overtaking record. Hamilton has shown that in an inferior car he can beat other drivers.
I'd like to see the statistics on that, considering how much of a charge Alonso went on in Monaco lol
Although random stat considering all the talk of Ferrari and their engine issues, Mass and Alonso have done the most laps completed of anyone. Massa has finished every GP, and Alonso has only missed 8 laps by binning it in Belgium.
