Some things as this New Jersey Native can tell you about being hit and I have on more than one occasion been slammed.
Call the police (eliminate you said, they said)
Go to the hospital. (The ambulence put on the siren and lights for me) many problems do not manifest themselves till days latter. Soft tissue injuries and torn or damaged tendons or ligaments.
Get all contact information including car insurance.
Write down exactly what you think happened as soon as you can. This will prevent the story from changing in any way. You will need this for insurance latter.
Take photographs of location and damge to you and the bike as soon as possible
Get a written estimate from two bike shops, produce receipts for lost gear.
Get witness names and reports if any.
Get a lawyer insurance companies got them so you'll need one two.
In your case its not that much damage for this you should be grateful, you are very fortunate. You can still file a report and should with the police. Call the driver and stress upon them that it will be much cheaper to pay you this amount of money than to pay the insurance company for the next three years. If they don't pay you follow through and file a report and claim. FYI New Jersey is a no fault state so often I had to deal with my own insurance since as a pedestrian cyclist I am covered by my own auto insurance. Its a mess. Insurance companies make money by not paying claims you must be persistent and dedicate yourself to it.
