Importing whole towns into a map?

I was wondering if it would be possible to import for example Oslo, Norway 3d model off sketchfab that is hyperdetailed and but it in blender then Beamng without having to change anything?

For example this, how would you get the textures to be unblurry and is there 3d models available that are even better than this?

 

It is indeed possible to make an entire map out of just one or multiple .dae files by importing them into BeamNG's world editor.

There will always be issues with textures, hitboxes etc, so no it's not just one click and it's in-game. There are some tutorials on this though and with some time and effort it's not that hard.
Good luck on this if you decide to make it a mod
