99% of the population is voluntarily carrying sophisticated tracking devices with self-reporting always on
even if the signal is off it catches up later
with SEVERAL layers of tracking

even phone makers have their own tracking layer sometimes
we know EVERY person that went to Epstein Island from their phone tracking and they didn't even have smartphones back then
Flock is just another lazy layer/databroker
The fact that driving is a 'privilege' doesn't negate your rights to be secure in your papers, the police should have to have articulable suspicion that your car is unregistered or unlicensed before they can demand you to display your plate.
