We are talking about different things. The thread talks about 3 things: 1. Speed limit data /alerts to show to the driver, 2. Speed limit data to use in routing and ETA, 3. Speed limit data to use in automatic traffic detection and showing traffic data /coding on the client /live map.
It would be helpful if the 3 suggestions are clear and the only thing they have in common is the words "speed limit"

Are you volunteering to make all the timely speed limit parameter changes to all segments across the world? Else, how would this database stay up-to-date? We already have whole towns that are still crap basemap road data, let alone lacking speed limit data.
And who's volunteering now to fix the base map and map entire countries with no base map?

I read through most of this thread. However, I was skimming to get the general gist. If I am missing a key element, please let me know.

I used a Garmin for years. I often drive more than 45,000 miles in a year, always with the GPS running. The Garmin had two problems with speed limits - they were not always correct and Garmin chose to display the actual speed in a red font if that value was higher than the "posted" speed limit.

I have been a Wazer for less than two months, but I find Waze to be more than adequate as a Garmin replacement. I particularly appreciate that I don't get nagged about the speed limit. (I live in Florida and the "real" speed limit, as observed by 90% of the drivers is either 15 mph over or 15 mph under the speed limit. You can always tell a driver from out of state because they are driving in between those two values...OK, that's an exaggeration (and I've been a Floridian for only 14 months, myself).)

I think there are many more future features to work on besides displaying the posted speed limit.

The current speed limit feature would be a great improvement for me. Roads in Spain are not always well signed and it is easy to overspeed without noticing.

It is one of the very few things I miss from my TOMTOM.

Apologies accepted.

Not at this time.

Speed limit has been talked about before. I've not seen it mentioned as being on the developer road map for the near future.

The trick is getting the data in, in the first place. Right now, waze knows how fast people drive a road. Not what they are legally allowed to do.

So, the question is... how does waze get this data into the system, if they do want to do it.

There are two camps and both have legitimate reason for and against it.
Some map editors don't want to have another layer of update request for speed limit changes
Some users think this is a needed feature as it is sometimes hard to tell what the speed limit is in an unfamiliar area, and it may not be well signed.

Right now... waze is working hard on getting existing features running better/faster, so I wouldn't expect it soon.

Maybe waze isn't for you;-)

I know of a segement where the speed limit changes 2 or 3 times.

More in keeping with waze's style would be color coding the speedometer in relation to the average speed of the road. Then you would know if you are moving faster or slower than normal.

Here's the real problem: waze really doesn't do a good job computing speed limits based on the GPS points. I just moved to a new area, and I've seen waze be half an hour off on my arrival time at my house. I can watch as I drive down the road, at the posted speed limit, and see the time get shaved off. How can waze route me the fastest way when the times are so bad? I know that going one way might save me five minutes (and cost me $4 in tolls), but waze says it would save half an hour? That might be worth it, except it's blatantly WRONG! Regardless of what they say, there must be some sort of default value for each type of road for them to even try to compute times on roads less frequently traveled. I'd like to know what those are.

There are several county roads I travel that, prior to my edit, were listed as city streets. Roads are paved, meet the definition of a minor highway, with speed limits on these roads of 55. Maybe if we could keep these at minor highways and not primary streets or just streets I'll get a better estimate on getting places in my new metropolitan area.

Yep, wouldn't you know it, another AM higher than me just changed my county roads back to Primary Street and locked the roads down. This person always locks any change down, so no one else can fix problems that develop. These aren't primary streets by definition on the wiki; they fit more the category of Minor Highway. So, if waze does take into account the type of road when there are few datapoints, I'll NEVER get a closer actual arrival time.

What's the normal speed on a primary street? 35-45 mph? What's the speed on a minor highway? 55-65?

I've got hundreds of miles, maybe thousands, in rural areas of the state where the speed limit is 55+ on regular roads. Some I set to Primary Street just to keep a grid of collector-type roads more visible and for good routing. They won't be set to anything higher because they aren't functionally a highway of any kind.
I understand what you're saying, let's keep the app looking pretty. But strictly following the definitions in http://www.waze.com/wiki/index.php/Road_Types_%28USA%29 are those rural 55+ roads acting more like a minor highway or a primary street?
