I used to live near a road that was designed similar to the "Continuous flow" model. It wasn't quite that elaborate, but Palatine Rd. just north of Chicago has "local" and "express" lanes. (Or was it Dundee Rd.? I forget.) I have no doubt it flows more efficiently than other roads, but I consistently had people drive into the wrong lane directly at me. I've never had that on other streets. So the question is - do these trade efficiency for basic safety?
