Some U.S. states are doing away with license plate registration stickers; instead, police cars will automatically scan every license plate they see and check the owner for expired registration and any other violations or crimes. In other words, police will investigate everyone they encounter (on the road), with no probable cause or other requirement. The technology to do it is not news; it already exists and will improve. Only laws can protect you.
