What if McLaren Honda dominate F1 from 2015 - 2020? What if Mercedes pull out...
Of course it has transpired to be a great decision for 2014 but who knows what the future will bring. I suspect it will be continued success, but the question posed by this thread really needs to be answered in about 5 years time, not after every time the Mercedes leaves its garage.
What if Mercedes reliability issues cost Lewis the championship this year, and McLaren are equally or more competitive next year? It is certain that driving for Mercedes is better than driving for McLaren this year (and last year).
Lewis's contract is up at the end of next year. Will he commit to a longer term deal soon?
