When you are in a dominant position, as Lewis has been for the past however many years, it makes sense to minimise risk. Perhaps you cede a single place in the knowledge that it will come to you later in the race, you will have another chance, and, if not, you go into the next race the favourite to win once again. You can see this reflected in Lewis driving style compared to his earlier years, and his consistency in finishing in the points over this dominant run. He has been extremely lenient in many recent battles, but has always won the war.
Conversely, Max, as challenger during this time, came equipped with a very aggressive, unyielding style.
Going into today these roles were reversed. Hamilton, as challenger, reverted to a more aggressive style. Max, in the ascendancy, should have realised the position he was in, the importance of merely finishing second if not first, and adapted.
He did not.
If roles were reversed, Hamilton would have ceded, as he has done many times previous. And that is the difference between a seven time world champion and a mere contender.
If it ends up costing max the championship, which I hope it does not, he will have no one but himself to blame.
