Well, this has been happening more and more in the last few races with Vettel... strange overtakes over the edges of the track.
I'm not a fan of either team or driver, and yes, he did violate the rules. However, if Alonso wins by making complaints about this, it's an anti-climax to the season!
If they are going to look at the 'incident,' then I think the FIA is better off not giving the prize to any of the teams.
