Be interesting to see the damage to her mirror - where it is damaged, and what the direction of impact (and severity) is.

If the impact goes parallel (or close to parallel) to the direction of travel, in a rearward direction - either twisting the mirror around on it's pivot against the window, or shearing it off, then it proves she was moving much faster than you - hence adding weight to the "must get in front at all costs" driving practice we all think she was trying to do (which is pointless, and very dangerous when you're in a near single-file processing meandering around obstacles).

If the impact is pushed in from the side - towards the centre of the car, then she has right to claim you moved onto her at similar speeds - you'd clearly be in the wrong, as it shows she was there for some time (to be able to match your speed) and you should have seen her with a mirror or head check.

And if the impact is parallel or close to parallel to the direction of travel, but goes forward on her car (not rearward) - dragging the mirror around to the front on its pivot, then it would show you scraped along her while she tried to avoid you. This would win her some brownie points in the blame game too.
