Hi Layft Greater.

thank you for your message and the links.

I agree with you (and with the best practices), "do not map for the router", and better to "avoid" these streets in the OsmAnd app itself.

Following your last paragraph, I think these streets are relatively narrow and have no lane marking. Thank could be the reason why I did not like to drive through them.

Therefore, I will not "resolve" this comment yet (neither #4393187). I will pass by hopefully in a few weeks. I will take note with StreetComplete of the number of lanes (I think none) and the width in meters (quite narrow). The new information will make, as you say, the router applications to avoid it naturally.

Have a nice day.
