Would be nice to get stats about your personal routes : average travel time between your first 2 or 3 destinations, average waze error on ETA (accuracy and precision - see wikipedia for the difference), time you spend driving per day, number of wazers you cross... one can invent all sort of fun and useful statistics.

How much time of my life did I lose in the car! That's what I want to know :)
How far did I drive for work this year
Stuff like that! Very useful

knew i wasn't the only one with this idea. i'd like to see Waze record the time my routes actually take each day, and have the ability to access/download these statistics.
the other ideas sound good too, but route statistics takes precedence (in my opinion). hope to see this very soon
