Lewis Hamilton dominated the Monaco Grand Prix almost from start to finish, yet ended the weekend with only a third place to show for his troubles. The result of a miscalculation by the team in the safety car period which followed the accident between Max Verstappen and Romain Grosjean.
Completely blameless then. Apparently not.
Looks like the team initially intended to keep Hamilton out, but concerned he would face Rosberg and Vettel on newer, supersoft tyres which would be much faster than the aging softs on his Mercedes, Hamilton himself asked to come in for a tyre change.
Mercedes made two errors. Firstly, it failed to calculate the delay Hamilton's pitstop would entail, dropping him behind both Rosberg and Vettel; and, secondly, they failed to tell Hamilton that Rosberg had not stopped and nor had Vettel.
For Hamilton's part he lost the race by failing to back himself. He didn't believe that he could hold Rosberg and Vettel back if they were on newer tyres than his own, and once the error was made he wasn't able to make the advantage of new tyres on the fastest car on the grid count and get past Vettel, never mind Rosberg.
It was a bad day at the office for Mercedes and Hamilton. And when that bad day results in a two car podium finished and extended constructor's championship lead, you get a feeling for how one-sided the 2015 Championship has been thus far.
