"Millions of drivers have signed up in recent years for electronic devices that allow them to forgo cash at tollbooths. The system makes toll-paying fast and convenient, but also creates a rich database of your whereabouts down to the exact second. And soon it may follow you to more than a tollbooth. In the Northeast, the E-ZPass system, which has six million tags in circulation, is being tested at the drive-through windows at two McDonald's locations on Long Island, and the agency that oversees the system is studying whether to expand elsewhere, including gas stations and parking garages." |
