After seeing Waze in action (iPhone) in busy California I downloaded the Android app. Both recently updated and improved.

Searching for groups, I found a fair number of Acura groups, and even a little fledgling Acurazine group (!).

But very few members. C'mon guys, get your Waze and say howdy when you see a fellow member cruising nearby.

 

I use it myself here in FL and its funny to find a few people using it. I have been in contact with the dev's when it was in Alpha/Beta stages here in the US as they are an Israel based company. Keep in mind that it is user based mapping and it may not contain all of the current side roads...until you map them. I found a few quicker routes after they had been mapped for my long trips. Just my random 2 cents about the app!
