They are getting pretty popular in central Texas where I live. I think they work best in a car only place where there isn’t neighborhood style traffic or pedestrians. This almost often means a location where a major road intersects a freeway. The one by the IKEA in Round Rock at 1431/I35 has been a great improvement, for example. The one on Parmer and I35 has also worked quite well. There is a similar approach, called “displaced left” down 1431 towards cedar park, however (Parmer and 1431) that has only been ok in terms of perceived improvement for traffic in the area. I will also note that they only started appearing here around 2015 onwards so maybe some design issues that you are talking about have been corrected in these newer iterations
