The video with the two MTBs going downhill: it seems to me that the long left turn that begins a few second into the video is way too long. It's easy to misjudge that kind of things (try to draw a road race track by looking at a single lap of it) but it could end up below the point where it started, or too close to it to be physically realistic. I was expecting to see a right turn at any moment but it kept going left. It could be another consequence of the lack of real knowledge about the world, similar to the glass shattering example at the end of the article.
