Roundabouts are almost always a bad idea. Thank God they are mostly a European thing.

Roundabouts are almost always a good idea, assuming there is sufficient traffic. They keep traffic flowing faster, more predictably, and with fewer accidents.

No, they just interrupt the flow of traffic by slowing it down. The classic pattern of side roads with less traffic yielding to incoming traffic on the main road carrying more traffic is the correct road layout that minimizes frustration and confusion. Roundabouts are the favorite tool of left-leaning, anti-car, vanilla soy latte-sipping urban planners.

No, they reduce the number of accidents, and also reduce the severity of accidents.

Good to know that I'm getting to my destination faster and more safely all because of woke!

Btw your 'classic pattern' of highly unbalanced traffic flows is specifically called out as a non-ideal candidate for a roundabout, maybe the urban planners get cow milk in their lattes after all.

Four way stops that require all traffic to stop for no particular reason are always a bad idea. They're a waste of time and resources.

Two way stops are OFTEN a bad idea, because they require two directions of travel to stop for _sometimes_ no particular reason. (And then they often cannot go without an extensive wait).
