Beyond Driven
Yup, I understand that part and can see why that is attractive. The bit I'm not understanding is why your nation chooses to trade that in preference of having better law enforcement.
One of the things that the number plate recognition has been used for, over here, is finding cars that either have no Road Tax or no Insurance. As prices of insurance rose it became more common for people to drive without insurance - which then meant that the chances of getting hit by an uninsured driver were higher, and then your insurance company couldn't reclaim any cost from the other party so insurance costs went up again! Number plate recognition has enabled the police to find such vehicles, and clamp down on uninsured drivers (Google says uninsured vehicles in the UK have fallen by 50% in the last 10 years )
All of which can be and is done already in parts of the States by reading the rear plate.
When a vehicle goes through an intersection that has camera coverage, images are taken of the front, side, and rear. Depending upon the quality of the equipment, the images from the front are clear enough to facilitate facial recognition. These images are stored for years.
Unless and until there is a set of national standards, the biggest problem is inconsistency across jurisdictions.
That said, as has been amply confirmed time and again, a front plate is utterly unnecessary. It is convenient for revenue generation, but hardly necessary.
Transit a toll road in a state that doesn't accept cash payments at the tollbooths (i.e., Florida). As if by magic, a bill will arrive at your home address in your home state (i.e., California). So simple.
Requiring just one plate and no silly HOV stickers would be efficient and sensible improvements. Bureaucracies don't like efficient and sensible. Less ways to assess hidden taxes. At the least, throw the money at technology. Simply scan rear plates in HOV lanes and mail the tickets. The first outcry you'll hear is from labor unions. And so it goes.
