I think they don't
McLaren pass allowed you to get the base mclaren roadster for 12$ after leveling the pass
Then they made it a little harder with the Aston Martin pass where you had to level the pass beyond max level and if you wanted the SUV (more exclusive than the roadster in that pass), you needed to buy the 40$ pass + level it to the max + pay another 20$ or so to get it
Then came Ducati collaboration. Here they removed the pass. There was no other way to get tokens other than spending money on token gamble box loot grate bundles and if you wanted the base version of the skin you needed to pay around 100$, the deluxe was around 310$ IIRC
The fact that we are seeing a crafter pass again is a sign (safe assumption imo) that their sales of the previous collab sucked and that they are trying to make things a little more affordable.
This is still beyond ridiculous imo.
