We aim for a single, publicly controlled, easy-to-use toll satellite system for commercial transport on highways, allowing the use of open source apps, enabling to process anonymised big data and thus improve both municipal and interstate traffic management. We insist that eCall and other similar movement recording devices have to remain optional and their data strictly anonymous, so that participation in any such transport monitoring activity remains a transparent tool of choice with public benefits, not compulsory means of government surveillance using outsourced contractors and opaque control mechanisms.
