As of 2 or so years ago, there's a bright flash every time a car drives through (taking the pic from the front). In PA, license plates aren't required on the front of cars...so what's the point of taking the pic from the front? I also haven't noticed any pictures being taken from the back. My assumption of why they're doing this is to compile nice clean labeled facial recognition data for ML training. Not only that, they can scan other faces in the car to see who you're traveling with.
