In Sao Paolo (BR) there is a test happening for traffic controls. A RFID chip is going to be insert into car's front window. The RFID antennas will be spread in some points in the city (like semaphores). So traffic management can check all registration information of the car, track it and a plus to Sao Paulo there is a traffic control in the city, a rotation, whose prohibiting cars riding once a week sorted by final number in the plate.

It sounds like a lot of improvement in traffic control and security, but anyway, I'm really worried about how to ensure data security... this is really an "Huge Big Brother"...

This is in portuguese but anyway: http://www.prefeitura.sp.gov.br/portal/a_cidade/noticias/index.php?p=13487

This reminds me of my dad, the most honest man you would ever meet. Never lied cheated and certainly never broke any law. But he would never get a vanity license plate with his name on it because he said it would be to easy for someone to remember.

It is a matter of how much privacy you want to give up for personal safety.

But the same is violation of personal freedom? I would not want to have such chip in the car.
