yeah, unfortunately DI crap is all a... necessary evil (for lack of a better term). It's a huge, multinational treaty and chances are slim it's going to change anytime soon.
there are ways around the paperwork and you can see that in action as the family is trying to sue the US over it. In the end they might get something.
I do wonder how car insurance works over there. by all accounts this appears to be an accident, and I'm guessing the car she was driving was insured.
