She thought she was in a video game. 

We have no idea what this poor woman thought was going to happen but getting clipped by a police car before being thrown to the ground and placed in handcuffs had to have been on her short list of possibilities, no?

The other possibility could have been the police shooting her, which by the way she was waving that gun around in the middle of the day is a very real possibility and one that she might have been hoping for sadly. 

This is one instance where police using their patrol car to nearly run over someone was actually a deescalation tactic.
