Self intersecting way, not clear where the actual waterway should be.

The two roads here probably join up, but I'm not sure on which side of the house. Someone should check this.

This is an orthopedist, selling shole inlays and special made shoes. I can't find a more suitable shop tag for that than shop=shoes though.

This intersection has been rebuilt very recently (no imagery is currently up-to-date), I fixed the part I drove through (and thus have GPS track of), but the rest needs fixing too. Roads speeds are also inaccurate going south on road 50. (Most likely 100 km/h)

Check if Basilikavägen extends to Karlsdalsallén or not currently. I would guess that it does

According to Bing and according to the Örebro öppen kartdata, the cycleway should be about here rather than over to the west. Someone in the area should check this out.

According to the road map from http://data.karta.orebro.se/ (public domain WMS layer for Örebro [note does not work with default JOSM projection, switch to ESPG:3009]), this entrance to the parking is quite different. On-site verification is required to determine if Bing or the open data is accurate.

Does this building actually exist? I can't find it on aerial imagery at least.

I seem to remember that this bridge is movable (swings to the side perhaps?). If so, this should be tagged as movable.

Should this thing be marked as junction=roundabout? It is partly signed as such: There is no blue roundabout sign, but the destination sign uses the curved arrows that are used for roundabouts. Also routing software gives very confusing directions in this junction.
