It's amazing what they'll do to avoid roundabouts! (not quite the same as the USAsians call "traffic circles")
Looks like this design (and similar ones) only take only cars and motorcycles into account. And possibly busses and HGVs. But what about cyclists? Pedestrians? Pedestrians consigned to wheelchairs? Sight-impaired pedestrians? Elderly pedestrians?
They seem to want lots of big cars over there, and this is the result: lots of cars => lots of traffic. Bigger cars make people feel safer. Cyclists / pedestrians will not feel safe, so they have to get cars too.
This isn't solving the underlying problem of "too much traffic" - for that you will need other measures such as "decent public transport", but that is not the american way...
Next you worry about pollution and obesity and wonder where that came from...
