Niki Lauda shoots from the lip and is consistently quick to blame Hamilton for any incident involving the two Mercedes drivers. Toto Wolff is far more measured. Within minutes of Mercedes' premature end of the Spanish Grand Prix, both had delivered their verdict. Lauda was, as usual, critical of Hamilton. Wolff gave a technical answer that hardly anyone understood but it did not say Hamilton was to blame. And it was right that it did not because while we mortals do not have access to Rosberg's data, we do have access to Hamilton's in-car footage and while we cannot say Rosberg was at fault, we can say, with certainty, that Hamilton was not.
