About roundabout: you're absolute right, no roundabout here. I removed roundabout and also did some other updates to cycleways, names, etc. About sources: it's important to remember that we cannot use Google Maps or Here as a source. First: there's copyrights. Second: if we'd blindly copy data, we would be doubling down errors to Openstreetmap. For example in this area "other maps" currently route drivers to cycleways and dead-ends due to recent changes around Pankkisilta-bridge.
