I'm not sure why roundabouts are so uncommon in North America.
Where I live, at a 4 way small street intersection, two of the entrances have stop signs with a roundabout in the middle. At that point, you might as well get rid of the roundabout.

You shouldn't. It's a poor design choice to cater to Americans who aren't used to roundabouts and yield signs. It makes things less safe.
It's not really covered when we learn how to drive. We get maybe a page on it in the handbook and one question on the driver's test. And then the road test almost never has one since they are so rare.
We also have a lot of rotaries/roundabouts here, too, so you get a lot more practice.
There is literally no difference between someone going straight and someone turning until they are right in front of you (unlike with a regular intersection where they would at least angle the front of their car to indicate turning).
