No chance of a conviction on this.
CPS wouldnt give it the time of day and in honesty quite right. This is just some woman who is trying her best to stop her premium shooting up. She may also be unable to tell her other half (if she has one) what really happend. Her insurance company are going to do everything that they can to avoid paying out.
Courts only have limited time and there are far worse crimes that need dealing with.
Just giving it the other side of the fence here.
Good luck with the claim though, CCTV will certainly help.
If you are comp then your insurer should have picked up the ball, fixed your car and be persuing her for the bill so you dont have to worry about any of this.
