Cloning is such an easy thing to do & so difficult to prove.
5 doors away from me they have a similar car to mine, albeit a saloon not an estate & 3 years older, but it is a similar colour & from the front looks exactly the same as mine.
If I were to have a set of plates made up in their reg & fit them to my car I could go out & commit lots of motoring offences & they would receive all the fines/points.
As long as the photographic evidence was pictures of the front of the car (like my offence is) then it would be virtually impossible for them to prove it was not them committing the offences.
