You could easily defend against this sort of tracking by living in a "15-minute" city, but you might wish to give up the habit of carrying your phone everywhere

You could easily defend against this sort of tracking by living in a "15-minute" city, but you might wish to give up the habit of carrying your phone everywhere. (and for the truly paranoid, as pointed out earlier on HN, there's gait analysis) (those who are tinfoil paranoid about being tracked by jurisdictions well removed from their local jurisdiction might wish to choose someplace urban with many passageways under roads and between buildings, or even better, subways?)
