I am less worried about Flock ALPR (which are aimed in the direction of traffic flow to read rear number plates) as I am about the THOUSANDS of facial recognition cameras installed in the last year in all four directions at nearly every intersection in southern Nevada and many many cities in southern California (LA notably excepted). These are mounted above the stoplights and aimed against traffic at stoplights to read faces.

I mention these locales specifically only because I have directly observed them. I would be surprised if this isn’t also happening in many other US metro areas, given how eagerly DHS/TSA/CBP/ICE are mass collecting facial geometries at every available opportunity.
