Hi Martinummo,

Looks at the chg sets i posted in the area you mapped to see details, parking, ways (bad practise to map ways along edges of areas, inter area gaps. parking access, layering (arcades same as building passage behove no layer is=n. and more.
The place to look is your stats page at HDYC (How did you contribute) at neis. https://hdyc.neis-one.org/?Martinummo
There's links to various lists, most pronounced, you've got > 600 routing issues to your name at OSM Inspector https://resultmaps.neis-one.org/hdyc-osmi-issues?uid=6698832, Also the Osmose links give more problems, often false positives but you have to study them before dismissing, else correct. Level 1 is grave, there's level 2 and level 3 too. Level one/two surely needs attention. Don't tag steps with access=yes or anything (an ID quirk), delete those else you allow horses to climb them too and granny in her wheelchair gets routed there and dangerous goods.
Level 3 mentions a lot of parking issues. Either add a tag parking=streetside or map a way onto it, don't stop at the edge, map to where cars really drive and specify when true aisle or a service way.

Have fun 'fixing'.
