This doesn't look like a reservoir. Could it be a detention basin, or maybe a seasonal pond?

changeset/122887108 looks wrong and should probably be reverted; most/all of these are just oddly-designed narrow hills streets, not actually one-way

This is just a turning loop at the end of the street, not a roundabout.

Unable to answer "Is there a shelter at this stop?" for node/6391939508 via StreetComplete 42.0:

There seems to be no bus stop here any more. There is a faded pavement marking where one perhaps used to be.

All the unmapped/missing crosswalks around this area seriously screws up pedestrian routing.

Is this patch of grass really a park, or is it just a small lawn area associated with whatever the building to the south is (as it appears from aerial imagery)?

Navigation thinks that this exit is a Right Turn Only exit, when in fact, you can make a Left Turn

Is there really a bus station here? It looks strange and unlikely.

crosswalk got moved to the intersection for some reason, should be fixed
