If you were alarmed by DEA license plate readers watching traffic on highways and recording the passing of every vehicle, that program is nothing compared to what will happen next.
You can bet these cars will each have a federally-mandated radio beacon by which cars can tell each other of their location, and by which our privacy of travel can be totally destroyed by government surveillance.
Actually it has already gone beyond the plate readers. Sniffing stations have been set up in certain states that appear to be just any road maintenance or construction sites but each car that goes by has their exhaust tested and if there is anything the gubment boys don't like you will have your plate scanned and a fine will be sent to you even if you have already passed the emission test for your state and purchased the sticker.
The slope just gets slipperier and more expensive
