Do you have a car? If so, call your insurance company. The police report will have her plate number and state. Ask your insurance company to find out who insures her vehicle. You should be able to make a direct claim to her insurance company without involving her. The police report and her own admission of fault will do it. That way she will at least be surcharged.

Other things to consider - was any of your clothing damaged? Shoes? Panniers damaged? You can get reimbursed from he rinsurance company for all of these costs. Don't undercharge your damages.
