4 races down, 15 races to go. Its now looking more unlikely for any team to stop Merc from wrapping up both championships this year. If everything goes as planned for Merc, this is when they could trap up both championship.
For construction, its going to be a boring season as Merc could possible wrap up the WCC in Italy or Singapore, or even earlier.
For WDC, I think its going to be one exciting season as its possible that the WDC could be decided at Abu Dhabi, IF Hamilton does win all the remaining races or suffer a DNF.
