The real conundrum is: once you have unique identifiers on vehicles - which pretty much all countries with cars have - where’s the line? Do you require people to visually read the plates and write them down on paper? Who is allowed to keep databases of the information? How do you prevent people from keeping their own private databases? How do you prevent someone from creating a dash-cam app that does GPS/time coded databasing of all plate numbers it observes while driving? If a neighborhood HOA wants to network all their dash (and fixed location) apr-cam information into a central database, when does it become too much to allow? And how do you possibly enforce overstepping of the limits?

Scenario: A HOA has fixed cam automatic plate reader information and video evidence that proves XM3 5D9 was out smashin’ mailboxes on Friday night. The HOA president is cruising downtown Saturday morning and finds XM3 5D9 parked on the street, using his dash mounted apr software, calls the cops (in a vain attempt) to have them come arrest the mailbox smashers who were recorded in close-up 4K high def night vision doing the deed from the window of their car. This feels close to the over-stepping limit, but what if there were no cameras or software involved and the same XM3 5D9 plate ID was used by the same people to make the same accusation of the same mailbox smashers, this time based on telephoto chemical film pictures?
