It's not a key life skill if you:
- live in central London (we had nowhere to park a ruddy car and even if we had, it would have been nicked/broken into)
- are extremely committed to limiting your impact on the environment (I can't claim this one, but am sure there are people who do).
It would be handy to be able to drive and I was having lessons (having sorted out medical grounds) but they are far too expensive - just can't afford it atm with dh being made redundant and freelance work for me much harder to find.
As for little old ladies, my MIL has to rely on lifts from members of the church to get to the doctors etc. - she did drive, usually drove herself as she didn't like FIL's driving, but has given up as she's old and frail and it just would not be safe.
I think it's far better for everyone else if she keeps off the road!
