Yes it is a tracker,compulsory from next year. It tracks your driving , where and when you go and how well you drive, lets your insurance / car owner / employer know if you exceed the speed limit as well. Big Brother has arrived!
They will soon be connected to the police as well and will track your car if it is stolen. (as well as automatically issuing speeding fines without need for speed cameras.)
I would have said Tony, Another EU Law that this weak Government fails to challenge like everything else, Did we win the 2nd World War? I am beginning to wonder.
