The first thing that occurred to me was that that particular type of fencing material is pretty flexible and there is clearly a post in the picture. All that would need to happen is for the material not to be secured to the post at that point - the fencing material would move out of the way like a curtain does when someone runs through it, returning to it's original position. Think about it, the driver obviously didn't care about his/her or anyone else's safety and wouldn't, to my mind, have thought twice about driving through the fence. The other thought that occurred to me is that it's not clear what is to the right of the fence post in the picture, perhaps just out of our line of sight is a gate or an opening in the fence. I'm not even convinced that there IS a fence to the right of the post, but it's not clear. Anyway, as you note, it's a highly edited video.
