Timing of the Traffic Lights
I think it would be a great benefit if you can us the data of every time a waze stops at a Traffic Light you should be able to figure out the timing for all the Traffic lights. Then some how be able to tell us when the next light is going to change so we can adjust are speed of course slowing down to time the lights and save fuel.

Could add to this. Traffic lights working incorrectly.
This would be especially good if you could give a speed estimates (below & above my current speed) to time the light so I don't have to stop. My commute includes a 10 mile freeway followed by a single traffic light that should be able to be timed and Waze provide speeds on the freeway that would allow me not to have to stop at the traffic light.
I like the timing part.
However, I dont like the part, where you would like to slow down based on the lights timing.
This is especially annoying for those following. And also that will contribute to a back up and caused the entire lane, to slow down, because one Waze user is timing and try to make the signal at Green. How about all those following, trying to make it or get closer to a traffic light. Thus increasing chances to cross that particular light.
Regarding the first comment - if the traffic lights work by sensors, it is still possible to calculate a time estimate, since the lights do have boundaries within which they must operate. Also, in the ideal situation of perfect information (I,e, Waze reporting from every car) it is possible to model and predict the traffic lights behavior. While the reality is not ideal, I believe there are enough Wazers for achieving this.
I will keep my Waze constantly on if you would calculate and show the speed I should go to catch my next green light, and also the time to the next red / green.
This would not be easy as many traffic lights (in my country) operates with a inductive sensor at non-peak hours. Meaning, there is no fixed time for traffic lights.
