I think you gotta go Max. I had my fears/doubts about his psychological state going into the race, but he was ice cold today and dominated.
Keep in mind this is coming from a Ricciardo fan: I think Dan is getting out just in time, as I really believe - though he'd never admit it - Max is starting to get in his head. Back when Max was having bad luck and/or youthful indiscretions every other race, it looked for all the world like Dan had him covered...but I think that was an illusion. Now that Max seems to be starting to assert himself, I think the writing is on the wall - if Dan were to stay at RB, he would be second fiddle to Max based purely on speed. That is why, again as a Ricciardo fan, I support and understand his move to Renault. It's risky, but RB is a known dead end for him at this point.
