Say that she was drunk and you were afraid that she was going to try to run you down again if you called the cops....cuz that is what she is going to say about you, or something equally dishonest. I am sure your lawyer knows this and will be prepared for the onslaught of lies from her, she is obviously the type to lie.
I hope that everyone reading this thread now knows what to do in these situations, sucks that it happened to you OP, people suck.
