Possible solution for online lobbies
I'm probably not the first person to propose this idea, but maybe I didn't use the right Google search terms. I'm happy to give credit if somebody else has suggested the following solution earlier:
I think it's too easy to achieve both the B and A licenses especially if you compete against the AI to win liveries in the F1 World menu. Perhaps it would be better to adapt the Gran Turismo 7 system of awarding licenses based on time goals and tests of driving ability. Because the higher level licenses would require a lot of practice and discipline to unlock, this would weed out a lot of immature players who enjoy being a menace. Players who don't have the patience for the license tests would probably have more enjoyment with the pure combat of the unlicensed races anyway.
