Boki, last days I was playing with it.
I have updated maps in iGO (2020--->2022)
Now, as Q4.2022 when I pick TeleAtlas and method for planning: Green then basically it's the same thing as Google Maps. The differences now are very very small.
So, conclusions:
Google introduced their new features in 2021/22 for few countries. TeleAtlas 2022 Maps works now very close to, while 2020 maps not.
So I do believe new hnr does the same or very similar job and this is not any magic google algo but maps, for which you need software: for example google or iGO to drive these features.
HERE maps not tested yet.
