She slapped him around while he was driving putting passengers, pedestrians, and other motorists in danger. At the point he hit her, he had to. He should have stopped much earlier though and ordered her off and radioed dispatch. I'd still vote to acquit. I think she was looking for trouble and she likely would have refused to step off and escalated just the same. The second she attacked is the second I would no longer see a woman but a person attacking me and endangering the people I'm responsible for.
