We now know that we really do need church. Not necessarily Christ, though they're probably the ones with the best set of morals
Citation please. On BOTH of these points. IMHO, I now know that church (note that you didn't say religion) willfully blinds one to evidence based decision making. And the Magdeline Asylums in Ireland sure put a lie to your second point...
ANPR has several problems - you need cameras on every street corner, it lets the government know everywhere you go, people can put false plates on their cars, etc.
(No, the government probably won't see any of those as a problem, but their opposition will...)
A GPS system could just measure distance traveled, not locations or any other data. The car could refuse to work if it doesn't receive a GPS signal that makes sense. If it's in a tamper-proof box then hacking it could be difficult enough that most people wouldn't bother.
So you don't trust plate readers, as the government can track you, but you believe that a GPS system will be used to ONLY measure "distance traveled, not locations or other data."
Do you have any basic understanding on how GPS type systems work?
Anything cut to length will be too short.
