From what I understand roundabouts make accident rate go up, it is the severity of accidents that goes down which probably still a positive.

That said I have yet to drive through a roundabout that I think improved an intersection in any meaningful way. Half of them work as intended but I find them less pleasant to drive through, the other half are just horribly designed and often have semitrucks go through them when they aren't really large enough for that.

"Studies of intersections in the United States converted from traffic signals or stop signs to roundabouts have found reductions in injury crashes of 72%-80% and reductions in all crashes of 35%-47%"

That's the argument I keep hearing, but I'm not sure I buy it. Fewer people might be injured physically but even low speed accidents can cost thousands in repairs if not total your car, so going from a few people being hurt a year to multiple people losing their cars or being forced to pay out thousands every few weeks doesn't seem like a win to me.
