Personally, for me, Vettel needs to prove that he can actually win without starting from the front row or overtaking others in the pits, because in my opinion he is just another hot lapper. He also needs to prove that he can create a good overtake on other front runners; fighting for the lead or fighting another great (Button, Hamilton, Alonso [Don't bring up Monza 2011], Raikkonen, etc.). You might be saying, "Vettel doesn't need to prove anything, he's a world champion! He broke records, etc. etc." If Vettel truly is one of the greats, or not another hot lapper, then he should show it in his driving. Best video I can find: Since there was a comparison to Hakkinen, I feel that this is needed: Now here's a compilation of Vettel's overtakes: Don't get me wrong, Vettel is an amazing driver, but to be compared to the greats at this moment is premature, because his Red Bull is arguably the fastest in the field. Maybe later on in his career will we see him in the 2nd/3rd best car, and fighting it out for the lead, but as of now I don't think we can call Vettel a great just yet, because he still hasn't proven to be able to keep a fight for the lead, apply pressure, etc.
