Unquestionably that is not how you want a world championship to be decided. The procedure at the end was irregular and Mercedes are right to be feel aggrieved. Ordinarily Lewis Hamilton (who was far more gracious in defeat at the end of the season than Max Verstappen was on last week's podium, when he flounced off) would have won under the anticlimactic condition of a safety-car finish. However, Mercedes should cease with their challenges against the result and just accept what has happened. Verstappen is not an undeserved winner. He has driven well (if aggressively) throughout the season, both teams have at various times benefitted from odd decisions, and yesterday's result was always going to be on a knife-edge.
