Here's one in Helsinki, Finland: https://goo.gl/maps/NoWE44KLKukEeq4d9

I also disagree that it is simple while you're on it although I have to admit that I'm not a very confident driver at the best of times so maybe that's just me.

There's one in Espoo, Finland (Suomenoja). It's apparently the "roundabout from hell", although I don't personally get it. https://www.hs.fi/kaupunki/espoo/art-2000005975273.html

I would consider myself good with following direction signs and being in traffic in general. However, I find that roundabout very confusing.

What makes it confusing is, I think, the overhead signs in the roundabout. It would be easier without them. Because the arrows pointing up also points towards the incorrect exit at the same time due to the round nature of the road :)
