Back in the old S1 days we had the credit system to lock out cars to noobs. It was not the best system and there were exploits to it that made it simple to get all the cars.
That said, on the whole it meant that people could not access the bigger cars in LFS until that had at least some experience. Something we have now lost.
Should the licence tests be used to unlock cars, so you can only use the car online if you have passed the tests, including the clean passing test, for that car.
The licence details should be part of your LFS profile as well so you can't use copied files etc to unlock etc.
