Please explain acceleration in Be a Pro

3 huge, massive, how did you not catch this issues with acceleration in be a pro

1. There seems to be no way to increase acceleration in game. The only way to increase acceleration is via trait points. 
   
   
2. Using trait points to increase acceleration only gets you to an 89 (if you’re lucky and have peak health), which still makes the 3rd tier of X factors like Wheels and Elite Edges completely unattainable. 
   
   
3. Acceleration seems to consistently decrease by 20-30 points every game, and there doesn’t appear to be a way to stop this. 
   
   

I know I’m not the first person to complain about this. Please address this.
