The SC rules are very vague at the moment and not very well thought.
Quite right. The only thing that bugs me about the whole SC controversy is that it's essentially an old topic. I've watched F1 long enough to see great efforts by small struggling teams (i.e. Sauber) being ruined by 'bad luck' of the SC coming out in exactly the worst possible moment - over and over again.
Yet, once it happens to Ferrari, the whole world must take part in their pitty and bad fortune and all rules must be changed and looked into.
Of course, I agree that the SC rules can and should be changed for the better. I still think Schumacher/Brawn got punished wrongfully in Monaco (it was essentially the race directors fault for giving conflicting signals) and that the latest punishments handed out by not being within the delta times to be a bit overexagerated - at least from what I have read from the teams about what happened there.
Having said that and coming back to Alonsos/Ferraris behaviour - I can somewhat relate to the frustration. Since Bahrain, they've been in the critics of the all too vocal Italian press due to their subpar and underwhelming performance. Alonso has also been highly criticized for his on track performance - not consecutively beating his, in many eyes inferior, teammate, jump starts, accidents etc.
Now, in Valencia, home GP and all, it was a grand opportunity not only for Ferrari, but especially Alonso to step up to the chase. The pace in free practice was very good and should have been a return to a top spot. They qualify 4th and 5th and everything looks extremely good for them (especially with Hamiltons car being damaged) right up until the safety car, where everything goes terribly wrong without them doing a single thing wrong.
If Ferraris form wouldn't be that crucial and Alonso not so heavily in the critics, the issue probably wouldn't be as big. But home GP and all - the frustration must be huge within the Ferrari camp.
Just like Schumacher as well btw - who has had his fair share of bad luck as well, having more than one race ruined by tough fortune. And on the other extreme, you have Button that's no doubt been the most lucky chap so far (not to take anything away from his very solid and clear-headed performance and making the best out of situations)...
