You forgot roundabouts with traffic lights.

Here’s one in Australia near Perth:

And I’m certain I’ve driven through other roundabouts with traffic lights in other states.

My honest take roundabouts with traffic lights are just traffic lights with extra steps.

In England we even have roundabouts of roundabouts https://en.wikipedia.org/wiki/Magic_Roundabout_(Swindon)

I’ve driven around the Hemel Hempstead one a few times. Very confusing when I first saw the sign.

Ooo! I like that one!

I know of a couple in NSW: one in Albion Park, and another in Bomaderry.

They work well when the peak-hour traffic tends to block some of the entrances. You can use the lights to allow the blocked entrances to flow, then turn the lights off out of peak-hour.
