Was discussing this with my Dad on the phone the other day. He is of the opinion that Lewis did nothing wrong, as the fact that Ron et al checked with "Race Control" that it was now fine for Lewis to attack again after conceding meant it was all lawful. My point to him was that Lewis didnt NEED to take Kimi at that corner. Lewis had so much extra speed on that lap that he could, quite easily, have let Kimi go into the next corner ahead (I remember years ago, the old "1 corner before attacking again" was a good rule of thumb for this knid of incident) and then gone at him there. But no, Ron told him it was legal to go, even when he was 100% sure. Lewis just obeyed the instruction from the team.
IMHO.
Sustitute the words FA and Football for FIA and F1 there and you have the same issue. All modern sports with that much money involved are biased to different teams/individuals at certain times. Still sucks though....
