Am I wrong to be mad or is she immature?!

My mother knows my car is not working and my husband is still working on his right now. It will be done soon but it is standard and I can't drive standard. However this is what she posts on Facebook and she knows I HATE when she does this! Am I wrong to be upset?! Or is she acting as immature as I think?!

Update: I have no car anymore, my engine is completely gone. No friends can take me,I have no family over here. No family over there will come get me and bring me home. Her car is also gone. She knows all this and yet still continuously bothers me, and posts personal stuff like this even though I have begged her not to because it just pisses me off & makes me want to tell her she's being a child. I literally no way up there. I'm lucky right now I have rides to work from my in laws while my husbands car is getting fixed.
