Why can't we?

In F1 25 you can race as either Konnersport or APX in Career mode which I think is a fantastic feature but I think there's more to be benefited from this, there should be no reason why people that own the right content shouldn't be able to use these cars in time trial or even grand Prix mode and multiplayer online lobbies or at least give them the chance to unlock the liveries and maybe even the helmets for F1 World like you could in previous years for me personally it would make my experience with the game much better and I'd certainly play the game more as I love using both Konnersport and APX car but sometimes when I load the game don't have the time to be doing a whole race weekend in career mode, I'd play the game more so and all it is is additional cars to use so it's not game breaking or game changing either
