Why doesn't the government want to make its appearance on Google Maps a little fancy?

I'm from Romania, and as you probably know, the cycling option for navigating the country is not available on Google Maps. It's like hell to me, and as I use the map daily, I've noticed that some buildings don't appear on the map!

I googled how to get that building on the map and found this. I tried submitting the building data there but to no avail... Instead, they redirected my submission to the Local Guide part of Google Maps and didn't use it because I didn't show them proof that the building was there (part of the documents). I said "Fine, I'll look them up" but guess what... IT'S NOT PUBLIC!

Then how should I make the map better or even if someone who has a building project in Romania will know more about it?
