I think the Dutch example the video cites is more a roundabout like this: http://thisoldcity.com/sites/default/files/images/netherlands_bike_lane_rbt.jpg http://thisoldcity.com/sites/default/files/images/netherland... which also incorporates the typical roundabout center island, and of course, no confusing light signaling system. Edit: as a note, some people are concerned about losing lanes, but if the lanes are (almost) always moving, and there is no redundant middle left-turn lane, you don't need as many lanes, freeing up the space for sidewalks and bike paths.
