Every single piece of the map that waze has all over the entire world has NO DIRECTIONALITY until someone either drives there or manually fixes the map. If you did not know this before, now you do. One of the biggest reasons for anyone to use waze is that it is possible to make the map reflect reality on your own, without having to rely on some big corporation to fix the map in your area in 5 years time or some other ridiculously long amount of time, or ever.
Complaining that the map is incomplete in a product where it is expected to be incomplete since it starts off totally incomplete is a little weird. Before we got a base map in Canada there were people starting from scratch to map their area. I did 1600 km of Vancouver Island on my own, without even one more wazer for the vast majority of that data, from scratch, editing every single road and intersection to get it working perfectly. Probably most parts of the world had to be done in this fashion, and I recall seeing an insane amount of different parts of Europe getting done in mere weeks from people going crazy at mapping around themselves.
A basemap can be a great shortcut, but isn't even necessary. The fact that the basemap doesn't meet your expectations is perhaps a letdown, but the whole point of this project is that you can make it what it should be on your own. And even people that never load up the map editor can help get that done simply by driving with waze turned on. Sure, that means the directionality of roads and intersections might not reflect reality for some time, but eventually it will. Editing just happens to be a faster way to that goal.
Perhaps waze doesn't do what you think it should right now. But with the help of wazers like yourself, it can, and in some cases in a very short amount of time. Obviously you don't have to use the product. Obviously you don't have to help in any way. But you can, if you choose to do so. Complaining that you would have to because of the current state of the map data is a little strange, though, given the very nature of the product in question. It is *supposed* to be completed by us. If that's not your cup of tea, that's fine. Don't use it then. Nobody's forcing you to. It would be nice if you had some spare time here and there to help, sure. But, really, nobody says you have to do any of it. But that is the nature of this project, and complaining about it makes little sense.
