"...It’s equally easy, though, to see how tech companies and techno-utopians will justify collecting and analyzing this data. Just imagine this future scenario: You drive to meet up with friends at a bar. Your phone/smartwatch senses you arrived in a car. After a couple of hours in the location it notices erratic movements and gesticulations out of the ordinary. The conclusion: You’ve had a couple of drinks and you might be driving soon, so maybe you get a push alert with the number for cab service later on in the evening when you walk out of the door. It’s an entirely hypothetical and invasive-sounding scenario, but one that’s not far from being plausible — at least from a technological standpoint."
