The Magic Roundabout is fantastically brilliant to drive through.
I used to whip around that thing in seconds (for some reason that junction always clogged up when it was raining), you just had to get into the mindset of effectively going the wrong way around, which was the way it was intended to be used.
If you think of it as packets of network traffic, I can see it actually being well suited for such a AI as the approaching traffic could be shaped to go around in the most efficient manner depending on the intended destination.
