At the moment if the route changes then Waze makes a chirp sound. I would like it to actually say "Route Change" or perhaps "Route recalculated due to change in traffic conditions" and then "Arrival time is now 7.34 pm". Or "Traffic delay has increased/decreased by 5 minutes". These announcements should be capable of being enabled/disabled in settings to allow for different user preferences. Personally I don't like reading messages on the phone screen while I'm driving - I would rather messages be read out verbally so I don't have to look at the screen as much - safer!
