I thought that had already happened, but I don't keep up with cell phone tech. My ancient smartphone has a setting that allows me to turn off location services, so I do. That doesn't stop collection of my cell tower accesses, but maybe it does some good.
That’s a good point and one I had forgotten — the cell towers can still triangulate you very well (that’s how they get good geo-coordinates for you if you call 911 on your mobile phone) and that data is available to the police via a court order. I don’t know how the data the get from Google is better than that.
