Not at all.

I watched the video from Ross's phone. At first, from that angle, it actually looks like he's lunging in front of Good's car, but then I remembered the other angle. He moved his phone from his right hand to his left hand so he could grab his gun. But the car is still traveling in reverse as this happens.

And when Good starts moving, the wheel is cranked to the right -- away from Ross. I notice something important: Ross did not back away when the car starting moving. He stood his ground. If Good was intending to run over him, all she would have needed to do was center the wheel, maybe even keep it slightly to the left. But no, she was cranked to the right, away from him. Ross didn't move at all, and didn't get run over.

From what I can see, Good hit reverse to execute a 2-point turn to leave, and Ross responded by moving his phone to his left hand so he could unholster his gun with his right.

But the fact is, Ross failed to properly act according to training. If you do believe someone is trying to run over you, the proper response is to get the hell out of the way, not stand your ground and shoot the driver. Cars aren't exactly known for stopping just because the driver is dead.
