Opinions are like noses, everbody's got one. Vettel's post-race penalty has inevitably raised many different views. My immediate one in commentary, knowing the corner from behind the wheel, was that he would get away with it, just like when he completed a move in Melbourne by running wide between turns four and five. But with more time, thought, camera angles and information I agree with the penalty decision.
As soon as Vettel was able to open the steering angle and apply the throttle earlier (for me the comparative condition of their tyres was irrelevant) then Vettel had an unfair advantage because he clearly intended to run off the track. Button didn't force him wide and did leave enough space for him to keep two wheels inside the white lines although traction there would be limited by kerbing.
As Sebastian and Red Bull began working on all the reasons and excuses for the move, they would have been better yielding the position and maybe grabbing it back before the end. If they had only been penalised just enough to reverse the positions this wouldn't have been a real penalty, rather simply ensuring it's always worth taking the risk as there is nothing to lose.
. Was it a bit too harsh?... maybe, but remember the precedent for questionable harsh penalties has already been set (ie: Hamilton qually a few races ago), so really i'm glad to see the consistency from the stewards for once... though will it stop me from moaning about the stewards decisions in the future, when it comes to my favourite drivers being called to account?... No!, probably not.
