I'll let everyone else debate the way to handle the woman...
thought I'd share an idea on fixing your sons car inexpensively..is he handy with tools....
check your area for a salvage yard...especially one where you pull your own parts..
a few weeks ago, our teenage neighbor girl backed out of the garage and hit my wifes ford escort with her SUV, drivers door needed replaced and rear door on drivers side was also dented and scratched... our neighbor immediately gave us his insurance info, told us to get an estimate and he would take care of it..
I looked at the damage when I got home from work, called my neighbor and told him not to contact his insurance company, didn't see the need to risk higher rates especially since a teen driver was involved,
I went to a local salvage yard, found a similar car {same year and color.}..that had the 2 doors I needed, with a little sweat{ removing the doors in the hot sun & pulling them across the yard in a wagon} and a total of 70 dollars{yep 35 per door} spent I returned home with 2 replacement doors,
I then told my neighbor not to worry about it, suggested we let it be a lesson to his daughter that neighbors help each other out..
after 2 hours of labor and sweat this past Saturday with help from my 17 year old.. the doors have been replaced,
