I don't mind the complexity of it, but they need to make it bigger to make lane changes possible. That and experienced drivers are too impatient for new drivers to figure it out.
Traffic inside the roundabout has priority, meaning you wait to go in until no one comes from left (roundabouts are always counter-clock). That difficult?
Yeah, everyone knows how a roundabout works but if you've never seen several of them combined like this then it can take you by surprise if you were just expecting one big one
