We have legal precedent that the police cannot use GPS trackers. A similar case was opened for the APLs in traditional speed cameras, but they were determined to be constitutional since you have no expectation of privacy on a public road and a camera can’t be used to track you like GPS. The networked APLs accomplish the same result as GPS trackers just without technically using a GPS tracker.
