More privacy required
I know about the anonymous option, but this is not my point.
I would like to have the feauture to everyone to be only your nickname from Waze client, at maximum, to be shown. So, if you're logged in to Facebook, as I am, it won't appear your picture from Facebook or your name either; instead I would recommend to shown only the Waze emotion and the Waze nickname. To avoid any persuit, identity anything else that makes you easy to be track.
So, only your friends will see your picture on the map and your name.
It's not just an idea, it's an important improvement for Waze continue could and with more privacy, safer.
