That plain sucks! Glad to hear that you are ok, relatively speaking.
In Nevada, a hit and run accident with injuries is a felony conviction. We do catch a fair amount of them after the fact, too. When I do these type of scenes I look for any paint transfer from the vehicle that is left on the victim's vehicle. Check your 919 and see if you can find any matching the color of the car. If so, I would call the detective who follows-up to send someone down to collect it for analysis.
If your state lab can't analyze it, the FBI can. Yes, your case will be far down on the list of priorities (homicides, sexual assaults, etc. come first), however a partial plate + a paint sample goes a long way in finding the a**hole.
Best wishes for a speedy recovery!
