Unfortunately doesn’t seem like this is an option. I tried everything from uninstalling the game to trying and removing permissions for FM8 in my Microsoft Account. Resorted to submitting a ticket and support replied today with this:
Doesn’t seem like this should be THAT complicated but I guess it is? Annoying. I decided to let a friend load it up and try it out before he bought it since he doesn’t have Gamepass and now I’m stuck with his career choices. Granted, I saw the above comment about retrying to bump stats up but I’m still stuck with a car I would not have personally chosen to start with.
Bummer.
