That's very unfortunate.
I've seen some cars that has the plastic lock like thing(the one used by supermarkets to lock our belongings in a cover before entry, so that we cant sneak in any products- which can only be cut) to prevent hub caps to fall. Even if it gets dismounted, it wont fall. Of course, you need to use a new one every time you remove it. Hope you could understand what i tried to say.
