I have a data block on my phone and it's interesting to see what data points they do and don't have. I'm not surprised they know when I'm at work or at home (I connect to wifi in both places), but random places along the highway? Did my phone connect to an open wifi network there?

Your phone didn't connect to a WiFi network, but it did scan for them. Then, when you got back on data, the scan information was connected with Google's database of WiFi networks and their locations. http://www.huffingtonpost.com/2011/04/25/android-map-reveals-router-location_n_853214.html http://www.huffingtonpost.com/2011/04/25/android-map-reveals...
