innocent, for now
but once the system is in place, or close enough, I bet all types of "authorities" and "services" will very much gain access to such wonderful tracking system. And they will, quietly, under this or that pretence, and this or that article of this or that code.
Obviously, all those driving older vehicles will become likely suspects, and monitoring their movement will be so much easier (by other means).
Oh, and wait for the system development disabling cars which are deemed to drive "dangerously". Insurance companies, ahoy...
