Why have the driving licence photo renewed every 10 years? Do people really change that much in 10 years? I think not! This could be extended to every 20 years or preferably abolished all together, with the exception of a new licence at retirement / 70 or whichever was deemed most appropriate.
Why does this idea matter?
The administration of this new process is a job, created by the previous government as part of a red tape, personel tracking system and would save money in the DVLA department, as the department administering this could be reduced in size.
