I don't drive, DH does, makes not one jot of difference anyway as we don't have a car and cannot afford a car let alone driving lessons/tests for me. DH passed before we had our DD's and we were both working and bringing in full time wages, still it was an expense that we struggled with.
DH walks to work, I walk everywhere, I NEVER beg lifts and use public transport if need be, very rarely do I use taxis.
It has never hindered my life at all (or DH's for that matter). If we go out for a drink/night out which is very rare anyway as we don't have the spare cash we walk, town is only a 10 minute walk from our house. If we go further we get a bus, train or occasionally taxi (I cannot remember the last time we used a taxi)
I have to go to a hospital outpatients appointment for myself twice a year, this hospital is not my local one but one that is a couple of hours away on the train. I love it I love being able to take a book and read in peace, or if I haven't got childcare for whatever reason I take the DD's with me and we have a day out.
I personally would be more worried about becoming one of those people who cannot cope with getting about without a car. Driving their DC to school when they can see the school from their front living rooms, how lazy is that; and before anyone pipes up about disabilities etc, the very same people cope perfectly well with walking their DC to school when they can be bothered to.
I would hate to be so dependant on driving/having a car that I never left my house because of it, like a friend of mine has done, they had two cars, hers needs fixing and is in-drivable. Her and her DC's haven't left the house for months other than at the weekend when her DH was home and they could use his works car. I asked if she wanted to walk with me to take the kids out to the library (10-15 min walk max) and she said her DC couldn't as they wont walk and she thought it was too far to push the pushchair. Her DC are the same age as mine. That worries me more than not being able to drive.
Oh and I don't drive as I am very nervous, I hate it and I am a danger to other road users so stopped taking my lessons.
