I guess it's all where you live.
I got clipped by a car hard enough to fold in his mirror. I saw a cop up ahead in a car. I pull up to the cop and the conversation goes like this:
Me: You see that blue van?
Officer: Yea'
Me. He just hit me!!!
Officer: Do you want us to take a report?
Me: Are you serious?
Officer: If you are hurt we can call for an ambulance
End of story.
The apathy of the NYPD to anything not involving donuts or death is simply amazing.
To the OP, you just do, you've still got to get where you are going.
