IF she drives and has got the same red shade in your pupils, that I would say that would be her problem....
Man, did she do a number on that Mustang! I don't envy your predicament.
It looks like she's not taking these little bumps seriously. Perhaps she needs to repair all the dents in the car with the $$ she makes (allowance, part time job...etc) . Perhaps when her wallet gets hit, then she'll be more responsible.
Just an idea.

EDIT: I wouldn't be surprised if she cracked the second tailight to make it match with the other side!
