My issue with this roundabout is that it's the worst of all worlds. It's unusual, and complex for cars. Given how bad the average driver is, I wouldn't want to be a cyclist or pedestrian dealing with this.
While it has its problems, Milton Keynes does non-car traffic quite well. It has "red ways" that cut under or over the main trunk roads. It's possible to reach most of the city without having to cross a major road.
While retrofitting this is harder, surely they could come up with something better, for that sort of money.
Oh and as for the woke comments. I've found describing it/replacing it with empathy/empathetic works well. It seems to really annoy the gammon crowd, while turning those on the fence away from it, hard.
