Between facial ID, phones and cars (not just the license reader, all of the built in tracking) there is no such thing as being out and about without being tracked. Between rental car, cell phone, computer login and credit card use etc, "they" could put together a pretty detailed map of exactly where I've been by the hour over the last week. Other than the cell blind spot in Mandera Canyon. But that's a dead end and I would have had to hike out to not be trackable.
Now if they could tap into my Garmin they could tell when I was sleeping.
