I like roundabouts over lights at small intersections. I still prefer simple give way/stop that changes the next intersection over roundabouts.
Lights suck unless there’s sufficient traffic.
They replaced a intersection near me that would get backed up very badly during rush hour with a roundabout that has a much higher capacity and never seems to get backed up.
I've lived some places where 4-way stops were just abused, like Sugarland, TX. England and Ireland are full of roundabouts, some of which are incredibly small, just a painted dot, and some are giant multi-lane white-knuckle nightmares. There are places with good traffic light setups, but traffic lights generally suffer from the same problems of sometimes stopping traffic for no good reason while also encouraging excess speed.
In my current city, I can identify at least 3 intersections that would be better as a roundabout, but I don't have my hopes up.
