I wish AT&T would use their cell phone hopping data to detect traffic jams and help their iPhone subscribers find the fastest route to their destination. A cell phone company can determine average traffic speeds by the check-in activity of cell phones traveling between cells. Most everyone is already carrying a traffic reporter on them. It’s just the data goes unused. I’ve been using Google maps for traffic data but the quality is unreliable and imprecise.
iPhones DO use Google Maps to show traffic congestion... but your idea sounds like a credible thing to do. BUT, I am not sure I want Apple, AT&T, or any body to have the ability to ping my location, direction, and speed because of the GPS built into my phone!
"Not sure?!" What am I saying? I trust Apple far more than I trust AT&T to not provide individual data to anyone... but I STILL DO NOT WANT THEM TO HAVE THIS CAPABILITY!
