Traffic square is a better translation, I suppose.

A few from Melbourne, Australia.
There are no magic roundabouts in Australia, but these are some in close proximity:

3 roundabouts in 150 metres - Hull Rd, Mooroolbark:





6 roundabouts in 450 metres - Lyndhurst Bvd, Lyndhurst:





A half-completed circular road with 7 roundabouts - Stadium Cct, Mulgrave:

Yes, but there's a major flaw in that logic - How would they be taught to navigate a roundabout when there are none? Put up a bunch of traffic cones in a parking lot in the shape of a roundabout? Sure, they could be taught how to do it in the classroom portion of their training, but that's just learning the theory of it, it's nothing like actually doing it in reality.

On another note, here is a roundabout in Spain (Madrid i think) that entirely defeat the purpose of a roundabout. (Do other countries murder their roundabouts this way, or is it only Spain?)

I've learned to drive in an area,where there are absolutely no roundabouts. Even the theory behind it is simplier than behind an all-yield junction. If someone comes,dont enter. Thats all.

Imagine if that attitude had precluded the introduction of freeways decades ago, or any technology for that matter. Nothing new would ever be introduced. And roundabouts aren't exactly rocket science - yield to traffic on the roundabout & on the left.

Single-lane roundabouts are straightforward, so they could be introduced on minor streets initially, with accompanying training sessions with cones held in parking lots (for example). Multi-lane roundabouts could later be progressively introduced.

The theory sufficed for me to immediately understand how a roundabout works... My parents never learnt about any roundabouts when they got their drivers license (one even didn't get taught anything). A short campaign about how to drive on them was launched after they started to become widespread, and nowadays nobody has any problems with using those.

So sure: we also had such a moment, but that's something that will always happen when something new gets introduced.

I wonder if roundabouts are common in Latin America,Africa, and Asia.

They are abundant in most of Africa and Middle East. Not that common in Latin America I believe.

Why the smilie? I don't understand. It looks like an ordinary roundabout to me.

Well, it seems to be quite large. Not outrageously large, but just large. There are many roundabouts that are bigger though.

In the very few cases where there are roundabouts in the Toronto area, there is usually some extra signage that prevents completely clueless drivers (not a good thing in the first place) from being "shocked".

On approaching the roundabout, there is a yield sign, and the middle of the roundabout has a regular "one-way" arrow sign (the same one put on intersections here) facing each approaching road.

I think one would have to be completely stupid to not know what to do. Of course, simply putting a "roundabout ahead" sign is more elegant, but this way I think there is no confusion.

The only cases I heard about were of people driving straight "through" a roundabout But I think if one doesn't notice a solid barrier in the middle of the road, one should have the driver's license promptly revoked.

I read that Japan doesn't have roundabouts.

It's also the only at-grade intersection on what would otherwise be several kilometers of freeway.
