What's conspicuously missing from both incidents is an effort to communicate effectively and cooperatively with the driver approaching from the rear. Using the slow/stop signal, as joejack has suggested, would be an example of doing that, but that's not all you can do. The point is to figure out what they're doing, and to let them know what you're doing, and make sure you have successfully communicated that.
But no one denies that there are aholes out there about which nothing can be done. However, it is not clear that that's what happened here.
