I like the GTD, a lot!
But I was disappointed when I watched one of the first videos of it on track and learned that track mode cancels the AC and then to get the best aero and performance, expectedly, it’s recommended to keep windows closed.
Come on. Give owners the AC and let them decide if they want it on or off.
The pros looking to set a record at the “Ring” will turn it off anyway. They know the game.
