Driving lessons

No, I learnt very early on as my mother was an only child and her father taught her to drive and she was a driver in the 2nd world war and she made sure that all three of her girls could drive - best thing she could ever have done for us as it gave us independence.
I did have a friend who learnt to drive probably in her 50s and she was never a confident driver.
These days I don't really like night driving, although that used to be my favourite time of driving when I was a lot younger, and that is because I now wear glasses for distance and I find car headlights very offputting.
Give it a go, if it's not for you, then at least you have tried. Being that you have had driving lessons in the past it won't be totally new to you. It does mean if you pass your test that you are your own person in that you don't always have to rely on somebody else. It can open up your life to a whole new world.
Good Luck.

I think a better idea would be to calculate the cost of learning to drive, buying a car, insuring it and maintaining it and put all that money into a taxi fund. You say you want to go out in the evening, but many of our friends in their 60s and 70s say that they no longer drive at night.

A colleague in her late fifties is learning to drive, she loves it, if you want to give it a go then why not? It might be worth thinking about whether an automatic would more suit your needs if you want to simplify the process a little.
