Yup I live in an area built around the time 'roundabout fever' has gripped urban planners, so there's quite a few around. To add a few of my personal complaints: - When there's a low traffic lane merging with a high traffic one, it's either impossible to enter, and you have to wait forever, or there's a traffic light cleverly hidden a couple hundred meters away, as to not break the illusion - They do work in the middle of nowhere merging two low traffic roads. However for every roundabout you have to slow down which breaks the flow of traffic, and consumes more gas. There's often a string of 5-6 of these things. - Having to turn to even go straight makes me queasy. Not too bad if there's just 1, but can be super uncomfortable when there's a string of them (which is common) - 2 lane roundabouts are crazy dangerous and confusing (which is the same). You might understand how they work, but the car behind you might not. Besides due to the geometry of the whole thing, you have to cut across diagonally to car traffic to get to the inner lane. - There's another kind of 2 lane roundabout, which is less dangerous, but only allows you to turn right from the outer lane. If you're unfamiliar with which kind you're facing, you might be in for a detour. Even if you know, there's often a fight to merge into the inner lane, which is not exactly pleasant or safe. I guess roundabouts are a niche solution that can work sometimes, but there's a whole internet cult for them, composed mostly of people who don't really live in an area with roundabouts.
