The game going forward has to improve and provide a more realistic experience for the players. I'm not suggesting in anyway that it should head in the direction of a full blown racing SIM, although that would be great I fully understand that they have to cater for all types of players and skill levels.
But there is so much more that can be improved to get more enjoyment from a racing perspective. Instead of spending all those hours developing more gimmicks, use those recourses to maybe improve the aging weather system and even create a basic helmet editor.
That alone would significantly improve the game, just those two examples. Spend more time to record better on board audio (Ferrari engine) being the perfect example.
Improve the utterly atrocious engineer chat and repetitive drivel he continues to spout out.
Little touches like a small debrief after each session with your engineer (Q&A) for example.
After a race, let us manually drive the car back to the pits etc.
Just focus more on the racing aspect rather than things that offer absolutely nothing.
Attention to detail is key!
