That’s true. Lewis has had one of his best years. Not being challenged by his teammate for most of the season also helped.For me Mercedes haven’t been dominant but more consistent than their rivals this year.
When you look at this years top 6, the biggest gulf in drivers is at Mercedes.
Probably followed by Ferrari where Vettel is usually faster than Kimi.
Then RB where things started off quite even, but poor reliability and then signing for Renault put a gap between Max and Daniel.
