Late, but regarding McLaren's wing:

Rule states aero components cannot be movable by driver. McLaren's case is the aero is staying fixed, but the downforce is altered by creating a stagnant region under the wing: this is similar to how a truck has a stagnant pocket in the truck bed when the tailgate is closed, thus actually making the truck more aerodynamic with the tailgate up than with the tailgate down.

Ingenious way of altering aero that is legal.

Regardless, you've got the fastest driver on that line-up in Ferrari with "the best car" he has ever driven. That says a lot, and Little Miss Sunshine will probably win the WDC.
