Yeah and it’s simple to reidentify anonymous location traces. The simplest way is to buy cell phone location data from apps, which is generally intermittent, but even with just 5-6 location/time pairs, you’re going to be able to positively identify someone, with the small caveat that there will be some ambiguity with members of a household that share a car.
