How are they supposed to step up their games? You know about the token system, right? Development is so limited in F1 these days, Mercedes would be coasting to titles on their PU advantage for another century if it wasn't for the rule changes in 2022.

A masterclass in politics that completely destroyed any kind of competition in this dying series. Oh, and he has and probably always will settle for a mediocre B driver behind Ham in the future, it's not like he'd promote some internal competition after the heated rivalry with Rosberg cost them a couple of wins.
