there are some reasons why there aren't any practice servers.

1 - it wont improve the skills of the drivers, doing a practice with half a dozen drivers will not teach someone how to start a race or to overtake. Everyone knows the combo, practicing offline with AI is actually more efficient.

2 - It will take people away from the grids, then people will start complaining that the grids are getting smaller, 'it's a desert' and some  expressions like those.

3 - knowing if the grip is 95% or 90% will make no difference at all on how you start a race or orvertake, it sure can make a difference on your laptimes, but not  on consistency.i AGREE

I agree but maybe having more information about cars/tracks before the race would be nice to practice and not having surprises the day of the race.
For example, on tuesday the Porsche Cup wil be in Riverside, but I couldn't find anywhere the version of the circuit (long, short...) for that race.
