Again, if he couldn't see her wheels, how did he know she's steering away from him and not toward him? You presume that he was aware of the direction of her wheels, when most likely they were not visible from the front of the SUV due to his proximity to the vehicle.
This was avoidable - all he had to do was not be in front of the SUV. And all she had to do was not gun the vehicle and hit an officer (whom she was looking at as she did so).
As I said before, both are at fault - if either one of them had acted differently, she'd likely be alive now.
