But why should it even be in cars so you can be tracked? People think as the commercials intend you to think - that this will keep you "safe" and you will be "rescued". They don't think about the fact that it's always there.
Watch for e-plates:
Excerpt:
The new e-Plates project uses active (battery powered) RFID tags embedded in the plates to identify vehicles in real time. The result is the ability to reliably identify any vehicle, anywhere, whether stationary or mobile, and - most importantly - in all weather conditions. (Previous visually-based licence plate identification techniques have been hampered by factors such as heavy rain, mist, fog, and even mud or dirt on the plates.)
The e-Plates project has been under development for the past three years at a cost of more than £1 million, and is currently under consideration by a number of administrations. It is hoped that e-Plate will be one of the systems trialled by the UK Government in its forthcoming study of micro-chipped licence plates.
Chipped plates
The plates are the same shape and size as conventional plates, and are permanently fitted to the vehicle in the same way. But each e-Plate contains an embedded tag with a unique, encrypted identification number that is transmitted by the tag for detection by RFID readers. Multiple tags can be read simultaneously by a single reader at speeds of up to 320km per hour (200mph), up to 100 metres (300 feet) away.
The reader network, which includes fixed location readers (for use on the roadside) and portable readers (for use in surveillance vehicles and handheld devices), sends the unique identifier in real time to a central system where it is matched with the corresponding vehicle data such as registration number, owner details, make, model, colour, and tax/insurance renewal dates.
