A car says a lot about its owner, perhaps a lot more than the owner might suspect.

In an extensive examination of automated license-plate tracking technology, the Wall Street Journal reports that the new tracking devices have the capacity to do more than a one-shot confirmation whether a car is legally registered.

Over time they can build a picture of the driver's habits, travel routes and destinations. And there is now the capacity to store the information cheaply and in huge quantities. One plate-tracking company, according to the Journal, has 700 million scans on record.

As the cost of plate-tracking technology has dropped, more and more police departments are acquiring the devices -- more than one-third of large U.S. police agencies in 2012 by one estimate -- many of them paid for by the Department of Homeland Security.

Law-enforcement agencies say they use the devices to identify stolen cars and ticket scofflaws and to track the vehicles of suspected criminals.

The privacy implications are chilling, especially to the International Association of Chiefs of Police that cautioned the devices can record "vehicles parked at addiction counseling meetings, doctors' offices, health clinics or even staging areas for protests."

In the course of their analysis, Journal reporters Julia Angwin and Jennifer Valentino-DeVries found that data about a typical American is collected in more than 20 different ways during everyday activities. And there is a growing capacity to match this data with credit card, cellphone location, online searches and social-network databases.

Privacy stands little chance where there is an economic incentive to intrude upon it. Indeed, privacy seems more and more like a quaint notion left over from the 20th century.
