Just tell him that it bothers you that she is not respecting your relationship. And also I think she might have some feelings for him and maybe trying to sabotage by doing little things like that. Has anything ever happened between them?

Ah I can see wha you mean. You can honestly say that sometimes You feel as if you're sharing him, you're happy that he has a good female friend, but you're not supposed to feel second place. She may be feeling like all his time is not focused on her anymore, and that now that he has a girlfriend she just wants to prove her spot as the best female friend. It's rude though she doesn't seem to get it, and it can be hard for her. You should also say that he's not her chauffeur and she can ask other people for rides. Or take the damn bus
