a useful tool – waze

I saw this on digg and thought back to my days at microsoft where I proposed making a similar product (using public transit actual travel times vs published times to predict the traffic levels) and was given a “oh that is nice” reply. This company seems to have made this work using cell phones as the source and gps:

There are a lot of great uses for this data and over time building a predictive model for traffic that is reliable becomes a reality.

I hope this is successful, and if it isn’t maybe I need to start writing code
