8 out of 10 times I use Waze driving to and from work, a route I know very well so I don't need Waze to show me my position on the map.
What I instead would like is a "trip computer" kind of interface, showing me things like my current speed, current speed limit (if known), maybe a color code for traffic ahead on route (green, yellow, red), ETA, current road name (nice to have, not need to have - I know where I am), live updates of incidents (needs to update themselves automatically), textual navigation instructions like "turn right in XX meters" (again optional as I know this route), and a few large buttons for Reporting, Alternative Route Now! (will open map view), Menu.
Police traps and cameras should trigger a large popup window when approaching.
Other optional items on the trip computer screen: GPS signal strength, GPS time, heading, avg speed, distance driven, distance to dest, etc.
It would be cool if the colors of this screen (and even the fonts?) could be customized to match the car's dashboard lighting, or to work optimal for night use or to save battery usage (black background, green or red characters, dim light unless police/cam warning).
