I was doing something similar to this over the summer when I sprained some ligaments in my left hand so it was painful to open the door using the "usual" left hand motion. The video seems to imply that reaching over your body to open the door with your right hand will naturally force your body to turn to see behind you (or to the side). This never happened in my experience, I can reach over and open the door with my right hand while still looking forward. Actually having to turn your torso has to be an additional learned behavior. I suspect that folks might make the turn at first if taught to do so, then eventually do the lazier thing and stop turning. As a cyclist who has been nearly doored on multiple occasions, I emphasize but the cultural change might be a bit too much to expect. TBH, I prefer jawbone3's suggestion of making the driver/car owner liable by default for "dooming" and applying a fine and/or surcharge.
