[Peter B - CV8]

My (late) Dad drove until age 96. Never had an accident or speeding fine in all that time. He did however start to misjudge things in his last 6 months & put a few scrapes on the car... We had a quiet word with his GP when it was time for his annual Drivers/Medical Cert time & the doctor told him it was time to give up driving. Dad was upset - but understood that it was getting a bit beyond him.
I then took him shopping once a week, Bank, Doctor, chemist etc & continue to do so for his widow. Luckily I'm self employed - but it does chew up a full day once a week & not everyone would be able, or willing, to do this.
