    Where does Google Maps get traffic data and how good is it?

    One of the cool features of the Droid is that the Maps application has traffic data. (You need to go to the layers and add the traffic layer). Unfortunately, it obscures the street names so it is a bit awkward.

    Where does the traffic data come from, and how often is it updated? Do I need to refresh the screen to get it updated?

    Do they gather GPS speed data from all the Droid users and use that to come up with real time traffic (like the late Dash Express, which was a cool idea that died). Or do they rely on state highway departments for data? Or do they get it from somewhere else?

    I believe they get thier data from the SHA of what ever state you are viewing. You should not have to refresh for the data to update

    They get it mostly from Google Maps users with mobile devices - Android, iPhone, etc

    The traffic info is great and it's pretty spot on! I will travel and it will show me that in a few miles it's heavy traffic and I think "yeah, ok. That's why I'm doing 80 right now". And sure enough exactly where it says the traffic is heavy, it's heavy. Definitely the best GPS I have ever used!

    Is it just me, or did that scare the hell out of anyone else? If Google is doing that -- and ADMITTING to doing that -- just imagine what they might be doing behind the scenes. Worse yet -- imagine what the Government is doing! If a private company like Google has this kind of technology available, just imagine what the Government has on us! Boggles the mind...

    At least cell-phones still have off-switches... Not that they're *completely* off when you turn 'em off... But hey -- pull out the battery and then it's definitely 100% off. (Sorry iPhone users -- y'all are S.O.L. on that one. Your battery is not removeable.)

    Our heads would pop if we knew HALF of what was REALLY going on.
