Not read anything beyond the first two pages so apologies if this has been covered before.
I'm all for mandatory retesting of all drivers at an interval to be defined. If stat show 5 yrs is best then why not retest then? Alternatively the photo license gets renewed every 10 yrs so why not make a retest a mandatory requirement at that point?
As a young kid I recall my alcoholic father was disqualified from driving for one year due to excess alcohol. Due to self imposed changes in that year he then didn't drive again until 32 years later when he hired a car to attend a funeral held at a location difficult to reach by public transport.
The fact that any individual is able to get in a car and drive after such a time gap simply should not be allowed to happen. If I had been aware he was even thinking of doing so I would have been compelled to stop him.
I know people will argue that why test everyone because of a thoughless, reckless few but who decides which individuals fall into that group without some form of testing? I also know that not having a license doesn't and can't stop selfless people physically driving but it this day on ANPR and real time access to DVLA records by the police enforcement could be semi-automated to some respect with the, over stretched, police force stopping cars picked up by the system.
