Well there is a better solution, win every race, then it does not matter... In 2008, A couple of early DNF's and a 3rd cost Massa his title, and Lewis by his own admission stuffed up the button in Baku, so he lost the title, that and combined with the 3x 3rd places of Bottas, in those 3 events, Max finished 2nd, 3 times, 3 races Lewis won...
You see there is a reason we have a season full of points, so that who has the most, get the prize.. It is not that simple, to point to the last event, is madness, it basically says, nothing matters, then what you are saying is that we should only have 1 point, for 1st place, 2nd to 20th no points.. But we should only know who won, once the court decides on the last race..
You cannot have it both ways, you cannot say because of the last event, the race director changed the result that caused Lewis to lose the title, and at the same time disregard 20+ events and what happened..
That you are hoping for a title at the last event, is stupid, that is not trying for 89 minutes and pissed off that the other side scored in the 90th minute, ref blows time.. You cannot be angry if you wasted 89 minutes, you have a season to gain points, waiting until the last race, hoping for a duff decision, not sure, but that seems a bad idea..
