Even if helmet customization doesn't get added, one thing I would like to see is the team sponsors and base livery added to your chosen helmet. say Mercedes, you would have the Merc logo in the middle of your forehead with the Monster logos on going around. Also have your name displayed on the car and race suit rather than the driver you are replacing. Both would add a bit more to that one thing I think is kind of lacking right now. I'd also quite enjoy doing formation laps and driving to parc ferme.
