Hey guys. I'm fairly new to Waze, and i've been updating the map around my area as best i can since joining (especially as there have been a number of roundabouts put in lately) and i've got a couple of suggestions.
Firstly: It could be handy, especially in countries where it's illegal to tell people where speed cameras are, to have speed limit data for the roads. With the current speed limit shown on the screen (above your speed, i would guess), and possibly an audible warning if you go over. There would have to be a 5km/h or so buffer with that, otherwise it would get annoying. And of course this would be something the user could enable or disable at will. If you wanted to get fancy you could have country-specific backgrounds for it, too!
The other idea just occurred to me now: Long term reports. This would be useful for roadworks, especially where a road is closed for the duration of the work. But it could also be for things like floods or roads being washed out or snowed under. I'm not sure how you'd do it, but like the speed camera reports, there could be a "no longer in effect" popup to let the map know when things are finished, or a timeout date in the editor, or something.
Anyway, just thought i'd see what people thought.
