What happened at the start of the Singapore Grand Prix will unquestionably be a key moment in the battle for the world championship. But what we don't yet know is whether it's the decisive blow against Sebastian Vettel, a mere detail in a Lewis Hamilton championship charge or a bump in the road that the Ferrari man will overcome.
What we can be sure of is that it's slashed Vettel's chances of winning the world championship. If history is a reliable guide, by more than half.
The mathematics of the situation don't make encouraging reading for Vettel. With six races remaining and a maximum score of 150 points, Vettel's current deficit is 18.7% of the total available.
