This is a big deal because I was told ( unofficially, grain of salt ) that Niantic was specifically collecting the location data from Ingress and Pokemon Go in order to map all types of travel routes for certain defense operations. For example: if 20 players walked 20 different routes through a park while playing, all 20 routes and their overlap is now mapped as foot paths. If it thought you were on a bike, in a car, etc. those routes are mapped, regardless of whether they were on actual trails or roads or private property. See where I'm going with my concern here?
