What they're talking about is basically a small concrete circle (sometimes it's not a circle, but a round-ish shape vaguely near the center) plopped down in a standard residential intersection (sometimes with a lot of stuff in it that blocks the view in case you were worried about knowing if someone is crossing the street on the other side). Better designs likely wouldn't fit without raising the cost a huge amount.
Seattle ones are works of art with trees and native flowers and sometimes art pieces.
They are more than just a small concrete circle. :D
Plenty of the ones near me are just a concrete blob, unless a little pole with reflectors counts as an art piece.
They sometimes have to keep access for fire trucks
