Vehicle location data
Vehicle location data is the big data collection of vehicle locations, including automatic vehicle location data. This usually includes times and often photographs as well.
Automatic number plate recognition
Vehicle registration plates may be automatically scanned with equipment, mountable on vehicles, that identifies an image characteristic of a registration plates, takes a photograph, and reads and records the registration number. Such scanning may be done by government  or private industry. Private industry collects this information for profit through, directly or indirectly, activities such as consumer profiling and repossession. Companies have collected over 1 billion scans of registration plates in the United States, stored in multiple national databases.
Radio-frequency identification (RFID) read from dedicated short-range communication transponders voluntarily obtained by citizens for electronic toll collection enable recording of time and location data at toll crossings. Scanning equipment has also been installed at additional, non-toll locations, enabling further data collection. Transponders have also been hacked, allowing reading and tracking by unauthorized parties. 
The American Civil Liberties Union issued a report on license plate tracking, finding that the vast majority of scans collected are the vehicles of innocent persons.
