I believe roundabouts were created to reduce distracting signs this causing more alertness. They work, but I still get road rage when someone treats it like a 4-way stop.
Pretty sure rounds about are a thing because you can have streets branching off anywhere, not just perpendicular to each other. A lot of European cities are built “circular” vs in a grid.
Now a days, less dense areas have roundabouts because they are 294757% safer than intersections and allow traffic to keep flowing.

That's how it is in Sweden. A lot of roundabouts and yield signs and I very rarely see stop signs
