It doesn’t really solve the problem of having a road junction - that’s still in the center and cars even come at worse angles than before- it just adds fluff around it.
On the other hand, it would probably turn into a tourist attraction and unique experience.
The joke is that you have to lane-shift to get out, the way you have to in most large roundabouts already.
Something people not used to roundabouts seem afraid to do, hence this is a design that “doesn’t coddle them” because if they don’t lane-shift, they end up in the middle.
