Waukesha County, Wisconsin. The roads are real, the businesses are real, and the 213 license plate readers are at their real, surveyed locations.
Everything else is fiction. The cars, the plates, the drivers. Yours is invented too. Nothing here ever asks for anything real.
Drive, take work, get photographed, find the cameras. Or run the network and see what it sees.
Pick a plate and a four digit key.
