It's unnerving to head to Google's location history page and see a map tracking your every movement. Although the location tracking can have a useful purpose (e.g., to map your outdoor walks for exercise or, I suppose, remind you of where you've been recently), if you don't have a need for this location tracking or reporting, you can turn it off.
To be honest, I'm not really concerned about location reporting -- I use Google Now and Google Maps' location data a lot -- but I'm not sure how many benefits there are to having Google save my location history.
In any case, thankfully you can delete this data or turn it off, if you're so inclined.
