I am not expecting Lewis to do anything else than start his holidays and "let the talks happening". He has been cool enough with every sh...i from Redbull drivers, even congratulating them. He fought back and did everything he has to do to secure a 8th WCC for Mercedes, which was not easy with Valteri second part of season form . SO it is up to team to decide to go for it or withdraw.
If he takes his 8th WDC after that, it will also be well deserved because he was there on top with his silver arrow not behind Ricciardo. Then the WDC will be decided on the track next year under competent FIA instance.
