It’s easy to say in competitive sport, and hard to actually action, but if Mercedes are convinced their car design gives a significant advantage, then despite all the panic and frustration by fans and the drivers alike, they should not be deviating course any time soon. The rules are around for some time, even if this season goes to the bin, if they figure out what the fix is then they’ll be set with a unique design that everyone will be playing catch up on. It could mean domination again.
Having said that what you said is also true. At some point they gotta cut their losses. But if the simulations show a big advantage, given where they are this season I’d keep going until I KNEW for sure that the potential either can’t be unlocked real world, or it’s next to impossible to get it set up to unlock it.
