Max Verstappen is BY FAR the best wet weather driver on the grid.
Ferrari, Mercedes and McLaren shot themselves in the foot for pitting early. Red Bull made an educated guess that there will be:
a) Full wet tyre conditions, so they gain a pitstop on main contenders
b) A crash resulting in a safety car, so they get a free pitstop
c) Red flag due to weather, so they can change tires for free
d) Red flag due to an accident, so they can change tires for free
and got 2 of the above, which resulted in them jumping Leclerc, Russell and Norris. Even with SC, they gambled and got the red flag they wanted. Max only needed to overtake Ocon and then he left the grid behind.
Now, if Leclerc, Norris and Russell didn't pit, I think we would watch a different race with Charles or George winning as I think Max wouldn't be able to dispatch all 3 in that visibility. But Red Bull gambled (and Alpine for that matter), scored a jackpot and got the best wet weather driver on the grid in clear air which resulted in pure domination.
Still have no idea why Ferrari decided to pit for the 2nd set of inters, putting Leclerc into traffic.
