Yes, Tora, with five races left he needs 54 points to be sure of the title. He can afford to come fourth (12 points) in each of the last five races and will need that only if Valtteri Bottas wins all of those races with the fastest lap (26 points each).
Knighthood? Doubtful. He's only the most successful F1 driver of all time, with almost certainly seven world titles to his name. Perhaps he should have ridden a push bike, played tennis or taught Princess Anne to shoot clay pigeons.
