I'm quite familiar with roads of that type - narrow, sharp bends with no visibility. I don't think there's much you can do. I personally would have given that driver only a modest black mark, for not coming to a halt when he/she saw you coming - which they had ample time to do if the positioning I can see in the video is any guide. It's what I would have done if I'd been the motorist in that place - although my car is a lot smaller!
But there have been times when I arrive at a totally blind bend at exactly the same time as a car, with absolutely no visibility beforehand, and I don't always hear the vehicle in time, especially if the weather's bad. Result: we both have to jam on brakes. Not had a crash yet, but there's no easy solution. Vigilance.
