I had a similar incident. As I was passing someone, they decided to change lanes into my car and hit me. It was a busy road, So I pulled over about 10 feet ahead so I had some room. This person decides to just sit there and never get out of their car. Finally after a few minutes I get back in my car because it's raining and they end up leaving and turning down the next block. I go home, and about a half hour later I get a visit from from police that I fled the scene.

I had to hire a lawyer to get the charge for fleeing the scene dismissed because it would've been a big hit to my driving record.
