lol I think they mean the car, since it knows where it is, can help car companies figure out who you’re banging because you end up in the same room as the other person’s cell phone a lot of the time while you’re at that address. (Cell proximity is already used heavily to correlate data points, so it can pitch birthday present ideas to you for your mistress.) In this sense it’s really no different than knowing what your favorite shoe store is, but they mention applications for abusers to track their exes and partners: thus sex life in itself becomes important.
