I don´t think adaptability is the problem here, not after 13 GPs
If it is, then I think we could say Kimi is not that good. If a driver needs some specific conditions to be fast, then he´s not a fast driver, but a driver who can be fast under some specific conditions, from time to time. Perez for example.
But I think Kimi´s problem is motivation, his car is just too slow, he´s strugling to pass Q2, not the goal he was targeting when signing with Ferrari again
