on holiday last year we were pitched opposite a couple who were both 85, they had towed their caravan from england to the south of france. they both looked really doddery but were sharp as a new pin mentally and we had many an interesting couple of hours in their company. their car broke down in france and their insurance company provided them with an audi Q7 to tow their caravan home, a car they were completely unfamiliar with.
on the surface, these two looked as if they shouldn't be allowed anywhere near a car, but the reality was they were perfectly safe, confident, competent and able drivers.
