There have been many occasions where people felt the best driver lost the championship, people have come up with various reasons why and whether it is to make themselves feel better or to justify their favourite drivers efforts, is part of the game. However, you can only drive based on the points system in place and that is what Nico has done, he didn't have to go all out to win the final races and if you want to win a championship you have to see the bigger picture. Hamilton has been faster and I imagine those botched starts will appear more important now but Nico did what was required and kept his cool and walks away a deserving champion.
