For me its clear either Toto/Lewis have pushed for James to take more of a role. Lewis comments seem to be having a dig as the car DNA seems to be similar i am sure Mike is too data driven. They all know by now what lewis needs they know his driving style but lewis comments seem to be "this car plays nothing to my strengths to go fast". Do you remember 2017 lewis was saying he wanted a shift in the car balancing as the 16,17 was hard for him to extract maximum with his driving style, and James listen and late 17-20 the car changed to having a more stable platform for him to extract from the car. So he knows what he is talking about maybe he wants James back as they spent a lot of time together perfecting the cars from 17-21, so he can get the maximum with his driving style.
I think it was around France when lewis said he had to change his driving style this year (2022) which he told the team isnt the quickest way for him to drive so he was hoping the (2023), they change the car so he doesn't have to change his driving style again.
