Not. Good. Enough. Admitting to errors of judgment are fine but this is the SECOND time such an “error of judgment” has DISADVANTAGED Lewis (Nico’s only championship rival ) and BENEFITED Nico. The other being Monaco of course. That is minimum of 25-32 points Nico has cost Lewis let alone all the points the team have cost Lewis.
Nico can be as apologetic as he likes AFTER the event but it doesn’t change a thing. Lewis is still trailing in the championship when he should be leading it by some margin.
What would you like Rosberg to do about that? Flagellate himself, perhaps? Apply to the FIA to see if they will allow him to transfer some of his championship points to Hamilton? Is there anything the team can do, given their commitment to let them race?
Personally I'd advise Hamilton and anyone rooting for him to try to avoid wallowing in a sense of injustice. Lots of drivers have won imaginary "what if" championships and can make a decent argument that they would have been deserving champions (Massa, to cite a relatively recent example). Lewis is better than that, he's already won an actual title, and if he wants to add to it he needs to forget about how many points he ought to have and drive according to the actual championship situation. He's got some points to make up, but not a huge number.
