I live in UK and have recently started using Waze and really liking it.
I do drive a lot and want to suggest some improvements/changes to the client that would make this software even better.
You already provide the users with the facility to report speed camera. Can you also extend this functionality to allow us to report speed camera's speed limit as well? Also, when the software displays speed camera warnings, it should display the speed limit as well. Another tiny issue is that sometimes the software gives audio warning of the speed camera and sometimes it does not. This is in spite of no change in my driving speed or the speed camera speed limits.
Another key and really useful functionality is to be able to report average speed cameras along with their start and end locations and their speed limits. This needs to be complemented by displaying the average speed camera along with the user's average driving speed when driving through the average speed camera zone.
If you look through an app called PocketGpsWorld (which is a free app), you can see the excellent speed camera functionality it provides. If you can provide similar functionality in your app, it would make it a killer app
Could you provide another UK female voice which is of a higher pitch? This would be usefull as a low pitched male/female voice gets mixed up with the songs/radio sound easily.
