Mercedes won’t maintain this form, and then his appetite may decline.
The next big rule changes are 2021 I think. Mercedes are likely to be the best team again next year; after that who knows. They have huge resources compared to everyone else and the modern Mercedes era came about through the last big engine rule changes, but Red Bull have Adrian Newey and he's the proven master in making the most of a rule change. Ferrari have huge resources too, but they seem to be headless chickens at the moment.
