wow - you did the right thing by calling 911. It doesn't matter what you did or didn't do on the highway - that other driver was 100 percent in the wrong. And she knew it too, otherwise she wouldn't have run off when she noticed you on your cell.

Some people take to bullying in their car as if they are the only ones out there on the road. It is scary to come across someone like that.

Thank goodness you are safe.
