Glad to hear you're not too badly injured.
File a report immediately or as soon as possible. You may feel fine now and begin to ache later. You could have serious injuries that take a while to notice after the adrenaline has worn off. You also have other damages. If your helmet got hit at all during this incident it needs to be replaced. If it were me I would pursue criminal charges against the driver as well as civil action against him if he/she does not agree to pay your damages.
Good luck and keep us posted.
