It’s a risky decision to upset Mercedes, as it’s entirely possible they could ‘throw their toys out of the pram’ and threaten to leave F1. MB bring a lot to F1, including their factory team, their development squad, and the engines they provide to others, etc.
I guess they will stay as they have ploughed so much $$$ into the 2022 regs car, but they really have nothing left to prove after dominating with 8 consecutive constructor’s championships. Who would step in to fill the gap if, on top of Honda (officially, if not entirely) leaving, Mercedes also withdrew from the sport? Is it time for a Ford Cosworth reboot?
I envisage a bit of politicking behind the scenes here, though I’d be surprised if any decisions are overturned. (I bet Masi has turned his phone off today).
