My repairs were supposed to take 11-14days...ended up over 80days....Don't hold your breathe. No matter how you try to push the matter along, it probably will not be enough.
And also, don't be too brash and dismissive about this lady not suing you. I do not think you are naive, but remember that most of the liability rests on your driving because you stated that you failed to yield to her; she had right of way. WHile you could make an argument that she did not do anything to avoid the accident, she could easily argue that she could not. And there really is no way of proving either case. People have sued over much less man, show some caution. I'm very glad that you have the moral character to admit full liability, but at the same time don't go around announcing your mistake to others.
Good Luck in your situation and I hope everything turns out awesome. AND BTW, your held up pretty darn well for her speed. I'm truly impressed at Nissan's design.
