The most frustrating thing for me is that whenever Ferrari/Mercedes encounter a problem, you can be 100% sure there will be a fix next race. But when Honda encounters an issue (like every race weekend), it takes them half a year to apologize, transfer the issue to sakura, analyze the issue, then bring a fix, but then it breaks down again.
Rinse and repeat.
They are not investing enough, not communicating enough with the race team, lack of manpower too probably. They will always be 2 steps behind. The lifecycle of this PU is coming to an end in 2 years? There will be new set of regulation before Honda catches up due law of diminishing returns.
