I don’t think the Mercedes issues are in one key area as they’ve struggled as a 3k+ person outfit to understand the issues. It seems whatever they change, it either just about works or is seriously out of balance on the car. The PR from the team is Lewis has been working tirelessly to understand it along with George, but they are no engineers. Drivers can only describe how the car feels and give feedback as to how they want the car to feel, it’s down to the engineers and designers to translate that into a workable package. Hopefully the reappointment of James Allison helps for next season in regards to technical direction, but personally I think there is too much ground to make up. When you think teams will spend £1M for a tenth of a second, Red Bull are five times quicker than that per lap. LeClerc admits the other teams feel ‘hopeless’ at the moment.While I can't agree with all your points on Lewis, I do agree with a few. I also sense that confusion with Lewis you mentioned. He is at a point in his career, IMO, where he really doesn't understand what Mercedes issues are. I don't think any of us do other than IMO, it's a downforce/balance design issue.
I don’t think Lewis has lost focus, I just think he comes across as downbeat in interviews because he’s frustrated and standing in front of a microphone is part of the job and something no driver wants to do at the end of a poor race. They just give the basic PR responses just to get out of there. Some here have made comment about Lewis’ age, but in this era I don’t see this as an issue yet. He’s 3 years younger than Fernando and cars are much easier to drive than 30 years ago when Mansell was wrestling his car to a championship at 39 years of age. Lewis is in great personal shape, perhaps in better shape than some drivers 15 years younger than him. He may walk away if the car doesn’t improve soon and nobody could blame him for that, life is too short and he’s got nothing left to prove in F1 really. He hasn’t got to get back to the front to validate his previous championships, he’s in the sport because he still feels he can win.
