ALERT
Speed Alert sound more volume, different type of speed alarm sounds alerting everytime over the speed limit. A switch to turn warning alarms off and on. SOUND is important when driving because all time the driver will be focusing on the street and not the screen, all alert sounds should have high volume, viz. for speed limit, etc.. should be more sharp, this makes Waze different from other gps navigation sys. and make driving safer. (sound could also say 'to slow down")

It would be great to be able to change the audible beeps, dings and click sounds to other sound effects, or potentially even making use of the phones ability to record sounds or voices and apply those as the alerts tones or voices instead. Many of the allerts sounds, including the exceeding speed sound are simply too quiet.
