Well, Jack knows far more about this than anyone else I think.
But I think if you did not already, you should report this to your insurance company.
I have no clue what this guy gets charged with, but if it were me, I'd just call my insurance company, let them know what happened, and let them handle it.
It does not sound like police ever enter the scene.
Of course we all know, you cannot pound blood from a stone, but if you have collision, your insurance company can give it a try.
