Maybe. It is difficult to determine what happened during the shooting. Did he grab for a wound. Did he grab for a gun? I don’t know. But I do know his mistake was made when he was pulled over.
The first time he pulled over, then fled the scene.
The second time he crashed into the snowbank off the road, knocking one of the 'shooters' to the side.
So I'm not sure what you mean. He had no choice at the speed he was going to do anything other than hit the brakes and hope for the best. If he was trying to 'go around', the snow stopped him.
