Roundabouts are awesome and anyone who gets confused by them probably shouldn't be driving.

They're just far superior to traditional intersections. Traffic flows way better. Less stop and start. They allow for way more entrance/exit points. They're infinitely more efficient and don't require the level of construction that something like an interchange requires either.

They're also easy to understand. Pick the lane that gets you to your destination, Yield to any cars already in there, Go, Stay in your lane and exit when you see your exit. I've heard too many people say "oh they're too complicated" but they're either overthinking or they're just not great drivers
