Hamilton didn’t lose the Championship because of a single failure, he lost it because of his poor starts at the beginning of the season. It seems strange that since he’s focusssed all of his time and effort on racing (the last 3 races) he’s been faultless and unstoppable.
Lewis lost the Championship and Nico deservedly won. Yes, the mechanical hurt Lewis, just like it hurt Nico in 2014, but it was within Lewis’ power to correct early on.
I’m a Lewis fan, but he has bitched a lot this season…the mechanic swap, Nico’s racing (and he’s had his own dirty tricks this year), the clutch, the clutch, the brakes, his mechanical…etc.
But, and it’s a big BUT, it’s not just the retirement that hurt Lewis, it’s the reliability early in the season which forced him into a 55 place penalty (which should’ve guaranteed reliability) again hurting his haul.
