I get where Perez is coming from, but sorry, Perez, you are very likely to be wrong on that one.
Max is quite adaptive, he went to the RB car and beat Ricciardo to a win in his debut event in the car. He never struggled to adapt to the RB that was built to Ricciardo’s liking at that time. Although Max was being beaten by Ricciardo, and still remains to be Max’s only team mate that max failed to beat in F1.
The reason why everyone struggles Checo, is because RB’s strategy has long since been to push Verstappen to a world title, Max’s feedback is prioritised and the car development is heavily skewed to him. So unless you drive with the same strengths as Max, you won’t adjust swiftly. That is why you and those before you struggled.
If Max had gone to Mercedes, like most drivers, he wouldn’t have struggled at all. The Mercedes is clearly employing a more balanced philosophy of developing the car to both drivers. It has a larger window of driving style input techniques that work with it, so it’s easier to adopt. I also think the team will more willingly build the car to you even if you aren’t the favourite driver.
Now, if Max went to another team that developed their car to 1 driver as much as RB likes to, then that’s a different story, there’s higher probability that he would go through a phase of adapting and getting comfortable with the car. I think he would adapt faster than you though Perez. I think Perez is a solid driver but I wouldn’t put it passed gasly or Albon to have done similar or better than him in the RB16B.
