"I never saw the programme (I'll find it on Catch up later).
Personally, I'd like to see a Medical for anyone over 65, renewable every 5yrs at least.
Before I retired I held a PCV/PSV for about 33 years. I had to have a strict independent Medical every 5yrs until I was 60, thereafter it was every 3 yrs. My driving skills were assessed at least three times a year by 'hidden shoppers'.
If a re-test might become compulsory I think it would be unfair. I've seen many people from 30yrs old and upwards who would have severe problems doing a re-test. "
