Well, I guess that tells us!
For what it's worth -- obviously not a whole lot in the higher echelons of Wazedom -- I drove quite a bit in Italy last spring. I used the app but, because the point didn't count, less than I do in the US; and it seemed to me that the level of acceptance there was much lower than back here. Very few icons on the roads, very few reports of road conditions, and almost no gas-price reporting: typically my prices weren't posted "pending confirmation" from others. At that rate, if and when the confirmation ever came, the price would likely have changed.
It seems to me that it would help build usage in countries such as Italy to encourage American Wazers to make ourselves visible, posting reports etc. as we do back home. But that's just my two centesimi.
I'll be' over there again in a few weekend and will be' interested to see whether usage has increased in the intervening four months.
