Robusta, I'm so sorry to hear this happened to your daughter, she must be very upset. I'm glad that she wasn't injured or worse. I hope she does okay dealing with the emotional aspect of this horrible crash. I know two people who died from careless motorcycle accidents, not wearing helmets either. It's good that there's no question about her being at fault for the incident, that's a very good thing. Hugs for your daughter.
I drove down a street near my house a few years back right after an accident, the cops were there and the motorcycle driver was completely covered with a blanket in the middle of the street. The lady who hit him was wailing on her knees, she was crying and so upset. I've seen them weave in and out of traffic on that 40mph stretch, he probably whipped next to her and she didn't see him.
