Exempt road tax also applies to road registered farm vehicles. It's not a new concept but allows confirmation of ownership annually.
As already mentioned - taxation was always inevitable and as ICE reduces in proportion gov will need to find an alternative to fuel duties. Road pricing is the likely method - because gov is stupid and it'll cost heaps to implement. The simplest answer would be a tax based on annual mileage read by an MOT garage (even if the car doesn't actually need an MOT) - prepay monthly and adjust the difference at year's end.
