Many of us are aware that, when in use, our mobile phones can be used by telecoms companies and security agencies to trace our whereabouts. However, few of us are likely to have been contemplating a scenario where our cars would contain built-in tracking devices enabling state authorities to have, in effect, a system of near total road surveillance. However, a new EU backed project, known as the Cooperative Vehicle-Infrastructure Systems (CVIS) project, may go a long way towards achieving that result. In particular, it is understood that the project, which is due to be unveiled later on this year, envisages that, by 2013, such devices would commonly be built into newly manufactured cars and that a universal frequency will be made available so as to enable state authorities to monitor the location of all cars fitted with the device. As one might expect, privacy and civil liberties groups are said to be up in arms about this development. It is understood that the European Data Protection Supervisor will make a formal announcement on the privacy implications of CVIS technology soon.
