If "frustrating" was the worst of it I wouldn't waste time discussing it, but suddenly forcing cyclists in a dedicated bike lane into a busy regular traffic lane with no alternative option available is pretty obviously a recipe for disaster - admittedly it's hard to find solid evidence of cyclists being killed by such arrangements (quite a few cases of cyclists being killed riding in such lanes, seemingly all due to moving vehicles crossing their path) but there are definitely cases of very serious injury.
