Great thread Alexi.
I’ll say yes he will leave but not for a while. Mclaren (esp with their engine switch) could suddenly drop off the pace even if it is unlikely for a team of such high quality, they could have some row, find someone better or Lewis may decide he wants to try something new.
The chances of him staying at Mclaren forever are so slim particularly because he is still quite young and coudl easily have a decade or more in the sport still. Although things are lovely now they can change. I barely know what’s going on right now with F1 never mind for the rest of his career :P If he did stay with Mclaren forever though I wouldn’t be shocked. The only other person who seems as devoted to their team right now is Massa and I really do enjoy seeing a driver actually really care about his team.
If he did stay throughout it all and there were some bad times chucked in I’d like Lewis a lot more for that loyalty. If he did try somewhere new though I’d probably rate him a tiny a bit more just for throwing himself in the deep end! Pretty sure he’d handle it fine though.
