Sorry to hear of your little incident.
If your insurance agent is cool, I would talk to him and ask him what he thinks you shoud do.
He will have some good advice, and won't act on anything unless you tell him to.
At 5 mph. you won't have any claimable damage, but what you need to be concerned with
is what this a$$h0le may do with your information.
Identity theft is on the rise, and you could see summons for things that you do not drive !
You need to talk to someone and get and idea of what YOU need to do to protect yourself.
Worst thing you could do is change your plates and your license.
It will only protect you from harm.
I hope the next time you plan on coming through NYC, you plan on writing me PRIOR to your trip.
I'll tell you when is the best time to cruise through this neck of the woods ...
