Traffic Light Timer !

Yes this is another "Waze" smartphone add on.

In brief. You spend a couple of minutes timeing the red / amber /green  cycle of your favourite traffic lights.  This is done by thousands of willing users. Eventually a database is created which can  forecast when each light will change.

So now you are driving down the road at 70km and the voice on your Waze GPS says if you drive at 88km or at 27km you can make the light on green. Else you are screwed on red.

You save fuel, time.
