I watched is several times. The miata holds his line. I was comparing it to how much gap there was between him and the side, which does not change. Isn't this the video that really shows what happened? I don't know what else is needed.
Jeff, usually when uploading it to YouTube, you're provided options about what quality you want to upload it. To watch it on a computer, it's not as critical.
To answer Ed's original question, I truly don't think whomever caused this incident even realizes it.
