That article is 'utopian'. All the uses now for the 'public good' also include the ability for these services to provide surveillance.
The 'smartphone' and 'smartcar' - can be tracked, on or off

Bridge Toll device on your windshield - can track your car on the highway
Street light cameras - can photograph driver and passengers - facial recognition
License plate readers mounted on police car bumpers can check parked cars
In Oakland, gunshots are identified by microphone and postition triangulated.
