Mitch Evans looked totally at ease on his way to a four-second victory in Mexico City. But this comprehensive triumph was not one founded upon some kind of magic bullet. What he and his Jaguar team did was inherently straightforward: they learned from their mistakes.
That notion is hardly a revelation, but it was an open goal missed by their rivals - their championship-winning rivals at that - and in turn it propelled Evans to the top of the standings.
Last time out in Santiago, again Evans was comfortable up front. The polesitter followed a pre-mediated strategy to use both of the higher-power attack mode boosts early on and he duly carved out a gap. But a software issue sapped his pace and left him prey at the halfway stage. He eventually fell to fourth - inheriting a fortunate podium after a penalty was handed to Nyck de Vries.
