Thank you for the name. Yes, that design. As I just commented below the stress point shifts to entering the roundabout where people crazily yank their car sideways to be on the proper lane. At all cost avoiding the feeling of having made the wrong choice. Kind of road rage psychology. And anecdotal, YMMV. I think here the soft turbo is a great compromise.

Seems like that from your description the turbo roundabout is only a problem for people who do not know it or know where there are going.

We have both types here. And now that I think about it, the turbo trades a bit more stress on first usage or a lot less every time after that. While the standard 2 or 3 lane is always similarly stresfull.

We do have a partially soft design of turbo roundabouts with phisical deviders and designated places where you can change a lane.
