He did that in a Toro Rosso and he probably doesn't have anything to prove to anyone. At the end of a career, some people care that people fight for them as the best while others look at stats and say it proves they're the best. Much like Schumacher, Vettel cares about the numbers.
Hmm, he got a pole and won a race in the wet, and some 5th and 6th finishes. The car didn't deserve to win so he gets props for that, but in the rain literally anything can happen.
Does he now get a pass on not performing forever more because the car won't put him on the front row in every quali, all because he won 4 WDC in a car that, not disimilar to the Mercs these days, was the class of the field? He's not done bad in the Ferrari, but he's not looked like a 4x champion wrestling a dog around the track like Alonso used to.
Nico implosion plz
I don't think Nico will crack unless something happens that costs him points and tightens the fight. He'll be cautious and be content to sit behind Lewis if need be, though he might struggle with the Red Bulls today.
If Lewis were to win and Nico were taken out or basically the points gap drops to like 5, then he might crack. He'd then have to probably have a straight fight with Lewis and I think Lewis wins in that situation.
