I'm really bad at Race starts and would like to either have a "Race start game mode" where you only practice race starts and maybe the first couple of turns when the grid is packed. Or if they add like practice starts in the end of the pitlane, like you just tell Jeff that you gonna drive through and pracrice a start.
I also think there should be an option where you tell Jeff to give you information about the car in front/back on every lap or even every sector. And if the cars around you gets any penalties.
