There is, i think you get it either for golding a challenge or getting gold in every challenge to complete that set of missions.
The whole menu book stuff is rubbish, but i am having alot of fun getting gold lap times on everything. I did all the licenses to gold first, then the initial set of missions to gold (i will go back to the endurance set one day), i am now in the process of getting gold on the circuit experiences. Ive managed to get gold on the Nurburgring (which is 9.5/10 difficulty imo) and a few other super difficult ones. Doing this has made the game a proper challenge.
In my opinion it's a PS5 game. The haptic feedback off the controllers is an awesome feature, specially on rally courses.
