I hope you got her license plate. That's careless/reckless driving and it would cost her 6 of her 9 points till they take away her license here in Canada. That's just plain stupidity what she did.
On the other hand, If I were you, there is no way in hell that I would let her pass me. It's a reflex for me, if I see someone speeding trying to pass me, I go faster/race with the person just to avoid the flying stones targeting my beautiful paint.
