One of the most common methods of tracking is using a device called, Automatic license-plate recognition (ALPR), Automatic license-plate reader (ALPR) or Automatic vehicle identification(AVI) depending on your location.
This device automatically records every license plate number it encounters. It is now being mounted along roads and in police cars/private vehicles in the US, UK and around the world. A police car on patrol can record 30000+ license plate numbers a shift. That data is often stored for years and can be used to create a detailed travel record profile of the vehicles it records.
ALPR, and most traffic enforcement cameras, usually use Infrared cameras to record this data. So we have created a special license plate frame that emits a high intensity IR light that effectively blinds the device's camera. This light is invisible to the human eye.
