Gatso 2: rollout of UK's '24x7 vehicle movement database' begins

A "24x7 national vehicle movement database" that logs everything on the
UK's roads and retains the data for at least two years is now being
built, according to an Association of Chief Police Officers (ACPO)
strategy document leaked to the Sunday Times. The system, which will use
Automatic Number Plate Recognition (ANPR), and will be overseen from a
control centre in Hendon, London, is a sort of 'Gatso 2' network,
extending. enhancing and linking existing CCTV, ANPR and speedcam
systems and databases.

It doesn't mention the impact on other road user types.

Parts of the system appear to be working already:

track a vehicle apparently involved in the murder of a Police officer
in bradford this weekend.
