Figured he was being attacked before he rammed.
That’s why we are only being shown the one video.
The video I see shows the car driving (slow or fast) into a pack of people. That was plainly stupid.
However, it does, if his speeds were low and not looking to cause malicious harm, lend credence to the story that he was looking to get out of the area, got caught up in a crowd of ANTIFIA, they attacked the car, he panicked, and floored it, not knowing that he was headed into the back of another car.
He then rams the stationary auto, panicked again, then hit reverse and got out of there.
The fact that he didn’t run out of town, and seems to have surrendered to the cops, also backs up that story.
