You can take a wild guess at the street names if you're reading them out loud, of course.

But what do you do when someone tells you an address on a street like Passatge di'Alió ("pasa je dia lio??"). You're not remembering that on the first try, you won't write it down correctly and later when you try to tell the taxista where to go they'll look at you like you're crazy. (This is from personal experience.)
