Interesting. The circles in the video seem to be a cross between two different types of infrastructure: 1. a traffic circle - that is a traffic calming device, and 2. a roundabout, which is usually a replacement for a traffic signal. I think it would work if the sight lines were better - i.e. no tall vegetation - and people entered the intersection at a very slow speed - maybe 10 mph. Think of the whole thing like a giant uncontrolled intersection - never assume that you have the right of way, and know that you will likely have to yield someone else at least half the time, maybe more.
The traffic circle in my neighborhood - the very first traffic calming project in Madison - has a 2-way stop on one street and through street on the other. It's not meant to dictate right of way, just to get people to go slower. We haven't had any problems in the over 15 years it's been there, and it's on Kendall, a major bike route.
