Changing the aerodynamics rules is one thing I really disagreed with for this season. It did create an advantage for teams with the resources to run endless CFD on their chassis, but Formula 1 should be about technology as well as driving skill. I really dislike the idea of turning F1 into an all out one car race. I am very opposed to the engine development ban as well. Especially after other team's drivers tested in Ferrari's cars after the whole reliability modification debacle and all commented on how the cars seemed significantly more powerful. But at least ALMS still allows significant innovation, though I hate to see that they're one of the few top tier series still doing this.
