What if Alonso yesterday finishing in P11 had set the fastest lap of the race? That would not have given him the extra point for fastest lap.
After Kimi got his penalty, Alonso was promoted to P10.
Should Alsono then be awarded the point for fastest lap?
AFAIK the rules aren't clear on this issue, but maybe I am wrong.
However, it seems good to me to have discussed this topic, before such a situation happens on track, in the hope the FIA takes note.
My opinion is that the fastest lap should be awarded to the driver promoted to P10 or higher, as he set that lap on merit, and the driver(s) relegated did something wrong (at least in the opinion of the race stewards). Had the stewards yesterday looked into the circumstances of Kimi's penalty during the race and declared their decision, Alonso would have been awarded the point for fastest lap without a doubt. (Of course if he had set fastest lap)
