Dang. I've had a fantasy of painting several fake license plates all over the back of my hatchback to help confound these cameras, but:
'Part of Flock’s proprietary tech determines the make and model of the vehicle and also notes if there are bumper stickers, bike racks, any other unique markings that would help identify that vehicle. That generates a "vehicle fingerprint" for every car or truck'
So in just the same way that ad blockers and other anti-surveillance tech actually make your browser stand out, obfuscating your license plate would also make you stand out.
