Glad you are OK. I don't think the police would call that a hit and run. The woman stopped, you looked at your bike and shouted "I'm alright," and she then drove on. I would have been falling all over my self apologizing and insuring that your bike wasn't damaged but that's me (and probably most drivers). Her actions could be construed as a response to the communication from you so, legally, she checked with the victim - no harm no foul.
