Just as letting people drive on incomplete maps is a complete waste of time, and naming streets or numbering houses is a complete waste of time. Your logic simply does not follow in regards to a user edited platform.

And as to the $$$$ reply, yes they paid for the speed limit data from some source. Waze can get that same data for free within a very short period of time.

The logic absolutely follows. The maps do not need to be 100% to be useful, speed limits do. The map will gradually learn of its own accord if left long enough, speed limits will not. Maps are crucial to the functioning of the map, speed limits are not. Look out your windscreen to see speed limits, if there are not enough signs then contact your local council!

Waze will undoubtedly bend to pressure on this and implement something, it'll be horribly labour intensive, data will be patchy at best and most folk will either switch it off or end up complaining on here about how bad it is.

So just like most the maps. People either switch Waze off, or complain about it, or a group goes to work and makes it work. A prime example of this was Las Vegas NV. When I first got CM status I wandered down there in response to a UR up in my state. Low and behold it was a mess and outside the Interstates and maybe along the strip it was a field of UR's and MP's and nobody was doing anything to make it better. I spent a few weeks working hard on it. At first new UR's were appearing faster than I could clear them, but gradually as I got first the main roads routeable and then into the subdivisions I started pulling ahead. And suddenly local editors started jumping in and editing. Now on the rare occasion I happen to bounce in to respond to an unlock request I see very few UR's and MP's and evidence of several active editors. Speed limits will work the same. Yes we may need some additional junction points in some places, or perhaps Waze can come up with another way of us marking the start point of a new speed limit. It probably will need a junction but perhaps they can come up with a visual indicator that the extra nodes are related to speed limits say a square node instead of a round node or a star.

Will this come, maybe maybe not. This weekend is the Waze meet in Palo Alto (I couldn't go), maybe this feature'll be discussed there, maybe not. Someone says to look out the window for speed limits, well sometimes you miss a sign or it's been knocked down, or badly placed or they just need more of them, but wouldn't it be nice to have an indicator on your screen of what users have said the posted limit there is? Who hasn't driven somewhat nervously for a ways on occasion when they realize they don't remember seeing a speed limit sign for a while and hoping to see a sign so they can know if they are or are not speeding.

I would have the settings screen where a user can opt to turn it on, have a warning caveat that the data may not be entirely accurate and to trust signs before Waze. But I can see it quickly being adapted across the road system. And errors and or changes would be quickly noted and corrected.

I'm not saying it is impossible, or that nobody would find it helpful; just that this feature needs to be evaluated in terms of cost/benefit; and compared to all the other things that Waze wants/needs to do.

The required effort to design, implement and maintain is typically underestimated; and while the feature will garner the appreciation of a number of end-users, it won't help Waze produce better routes, improve the performance of the client/server, or pave the way to any future capabilities of which I am aware.

So if you are sitting at home with WME editor open and the built in functions how are you to determine what a speed limit is for a road segment, where is begins and where it ends? Remember the example where the sigh is knocked down (ie Street View and similar of no value).

Does your area have some government published speed limit data that can be referenced?

I think the working assumption is that the speed limit data would be entirely crowdsourced from drivers on location, requiring no attention from Area Managers. (Whether that is tenable is another question.)
