Flock cameras are oriented to read rear plates. One would need a camera similarly configured + a billboard some distance in front, or perhaps 2 billboards, a 1-2 setup + payoff combo, the camera behind the first billboard, and the dynamic text on the second. Pulling up other public data correlated to the plate - where legal - may make a splash. I'm thinking addressing the car owner by their first name.
Right, but also remember that they're set up to analyze other vehicle traits, including but not limited to: color, make, model, body damage, panels that are a different color to the rest of the body, wheels, decals, bumper stickers, tow hitches, roof racks, etc., so even if they can't read your plate they can try to build a vehicle identity, and when they do get a plate capture, they can retroactively apply that to all other sightings of the vehicle.
