>Why can't I put here nice route for others to follow?

Because it's an arbitrary personal route. This data is not verifiable and subjective, it's not marked and not publicized as an "official" route. I can make so many IMO nice routes you'll tire of managing relations when editing roads. They'll also create noise on maps like https://hiking.waymarkedtrails.org/ . There are many nice routers which can help with creating a custom route.

Every mans right doesn't apply to yards which is the case here, that's why I'm curious.

"Luba viibida võõral maatükil, välja arvatud õuemaal, eeldatakse olevat, kui omanik ei ole maatükki piiranud või tähistanud viisil, millest ilmneb tahe piirata võõraste viibimist maatükil, või kui tahe piirata viibimist ei ilmne muudest asjaoludest."

The problem I have with it is that it looks like your personal route. If everyone starts to add them we'll drown in them. There are more specialized services for this like Komoot.

>There was no problems passing private properties.

The exact place I'm talking about is here
way/61328529
I'm kinda interested if the owners are ok with it or they just didn't see you / bother with it. It looks like a shortest route between Keila and Saue and is likely to be routed through. Access tags could be set there.

I once hiked abroad on an official route through private property to be greeted by a dog who didn't want to let me through.

Hi, what's the source for these routes?
relation/6535295
relation/6562171
The northern one even goes through private property, I wonder if it's still accessible.

Hi, you probably wanted to use
building=roof

Can confirm that there are signs "on the ground". Added name and source:name=suvery.

The schools look duplicated and I can't see any buildings there. Maybe imagery is outdated.

Nice fix for nonames, was this some automated change?

There are some small strange things like Aru loosing wikidata
way/8016649/history

Not sure that this road should have lost tracktype way/641957435/history
Of course it's a bit confusing since it's not a track anymore, but I think it should be ok to have it since highway tag is about purpose of the road.

Tasuja pst way/30908948/history
1) highway=footway and bicycle=designated are uncommon tag combination which should be avoided, this I've fixed right away
2) Tallinn GIS thinks this street does have a name https://gis.tallinn.ee/veebikaart/ (I'm not sure if anyone has asked permission to use their data, but that can be done). I'll try to check if there are any street signs.

You can also check why the highway type was changed here changeset/130798351

Bicycle parking is on the side of the square and can also be accessed by pushing your bike. I'd say using access tags which are about access by law for the whole square is wrong.

I ride bike a lot, but as a pedestrian I don't like sharing infrastructure with bicycles and we shouldn't direct bikes to places where they don't belong. Bolt cyclists often don't care about safety at all. So I'm not sure about Tammsaare park too. I don't want to be too correct with access tags either, but my common sense is a bit different.

Hi, why did you add bicycle access to Vabaduse väljak? It's explicitly forbidden https://www.mapillary.com/app/?pKey=658363728461940&lat=59.433158900883&lng=24.744026637781985&z=19.9&focus=photo&x=0.7973632509441009&y=0.3944349350242621&zoom=1.9419607394178495

and are there signs in Tammsaare park allowing bicycles?

I've merged those ways back. In this place pedestrians and cyclists compete for space all the time anyway. Also added a service road. Now routers which prefer common use roads will use Pärnu mnt and routers which are ok with a bit of walking can use footways there.

This bicycle road actually makes more sense if you route from Estonia theater to Mere pst as there is a bike lane from that direction. Not really sure you're allow to cycle in Tammsaare park. This should be validated.

This looks like a mistake

Please don't blindly ignore warnings.
It's very hard to find things you broke after you've uploaded them
Here you can see for yourself that the road is broken

Here a parking multipolygon got broken, it's not closed on the building's side

Don't you think that way/1155390146 looks a bit close to the cycleway? I think that having one way for bicycles and pedestrians was better there.

And here you drew footway on top of the red bicycle way

Hi, when modifying road geometry like on Priisle tee / Ussimäe tee junction please take care of the bus routes. Judging by another changeset something had to be fixed

added by dgmapping

For some of the gardens you've added there is also a good tag
landuse=allotments found under garden allotments. Doesn't necessary make your leisure=garden invalid.
landuse=allotments

Nice!
Consider adding highway=path. "terviserada" in the name seems to suggest that this trail is used in summer also.

Hi, you've removed
highway=footway from here. But I assume you can still walk here at least in non-snowy weather. Map shouldn't be changed back-and-forth every season.

highway=footway or maybe highway=path should probably be returned

Judging by aerials it's a pump track and bicycles are the main way to use them (you can "pump" with your weight instead of pedaling)

https://en.wikipedia.org/wiki/Pump_track

cycling=pump_track seems to be used 313 times, don't see the reason to remove it.
sport=cycling suited this better too than skateboards, though both can be present.

Maybe someday I'll try to change pump tracks in Estonia to somewhat similar tagging. (my last change to track just added some tags)

Where did "Laiaküla mänguväljak" name come from?

The landuse=commercial could stay as it is correct. It doesn't need a name or an address though.
