Roundabouts can work great in some areas. A large downside to them is their large footprint, you need a lot of space to fit one in. Because of that you find them more in rural/city outskirt areas with lower volume traffic, just because there is more area to fit them in. There are 2 or 3 intersections in my town that desperately need them, but the rest of the lights are just fine. You can’t really put roundabouts in a lot of downtown areas. One thing I really like about them is that they deter speeding. Putting them near school areas close to each other will make the drivers slow down in a way that green lights just don’t.
