Roundabouts just work with no power or fancy electronics. Those cost money to maintain and install as well as don’t handle a few cars coming from each direction without impeding one. Slowing down and making a slight turn does not compare to the fuel and maintenance cost coming to a full stop and getting the cars mass moving again. And regardless of it being “hard” to see pedestrians the statistics back up them being far safer: you have to be an active participant and look rather then “green means go” and not pay attention. I suggest watching that video I linked. I’ve driven in a number of countries and the ones with more traffic circles were always more enjoyable + easier as well as subjectivity had better drivers
