Hi Hilde...
You need to zoom in - using the scale on the left hand side - it goes down to street level

(If you click on satelite view then in some built up areas even the houses come into view as well) How detailed do you want it to be :D
You can erase your entry and do it again if you like....
-EDIT-
I'm sorry

I just tried it over Belgium and you are right - it's not very good is it - although the Satelite view is better so try that.
Unfortunately we are in the hands of Google but I'm sure Techadmin will upgrade us as and when possible.
