Driving:when will you stop?

[shootingstar]

Just found out my father had his driver's license renewed after he got himself retested. He will be 80 next month. Been driving since his mid-30's. For past few years he has quietly and voluntarily withdrawn from driving in situations that he feels abit less comfortable due to age: ie. he no longer drives at night, no longer on expressways and high speed major highways and no longer out of town. He does live in a city of 2 million people.

We are secretly glad he has quietly and voluntarily withdrawing himself slowly from driving all the time/alot. He has no respiratory nor heart problems at this time. He is mobile and only requires reading glasses.

It got me thinking: As cyclists, we might tend to pride ourselves as being independent and free on our choice transportation. Same perhaps for those of us who are car drivers.

So when do you think you would stop driving when you get quite old? On doctor's/family's orders? Or voluntarily withdraw?
