@HeadlesssApe Hi, I must say that you have done great job with that document. I don't know if it will be somehow considered by Criterion or EA, but still it is great that someone cares.
I didn't read the whole text perfectly, but if I can add some of my opinion here...
One is to change or add possibility of swap cars during free roam. Now you always have latest race car, when back to free roam and if I am correct there is no way to swap cars during day/night without losing progress and not finished races. At this moment you can easily end up with car for drifting in cop chase, what is not ideal, right? So free roam car and race cars should be separated. For free roam and getting heat I would like to use different cars and setups, then in races.
