If I am in via Giovanni Botero, I can go ahead to piazza Solferino; instead this is not possible according to current map configuration…
Thanks
That maybe, but you’ll get a better response if you go to Italy forums. Most of us here might not have rights to edit in Italy, 
The entire map of Italy has been locked due to vandalism. See the details here: http://www.waze.com/forum/viewtopic.php?t=37513
For help with this, head over to the Board index ‹ Country (Language) Forums ‹ Italy to work directly with other Italian Wazers.
Thank you for the hints - I’m new to the forum and didn’t know about the italian one…
