I think that there's something cultural going on, as well. I am from a country where everyone is expected to drive and the majority of people get their licence at 16. Because it's simply expected, people who don't are very rare. Obviously, there are people who have very legitimate reasons to not drive,due to physical disabilities. (But I have literally seen a woman born with no arms drive a car.) Driving in my home country is the first rite of passage into adulthood, and I would say that someone who cannot drive for any reason other than medical disability would be considered somehow not quite a proper adult.
I also notice that women in the UK are less likely to drive than men. I have looked at the statistics... In the US, the number of women with licences is also less than the number of men, but in the UK the difference is significantly greater.
I have seen posts on here over the years from womwn saying "oh, I can't drive. I get too nervous. I can't focus." For some reason, this exasperates me. I don't necessarily blame them, but I blame the culture that I suspect has contributed to the situation.
I also remember a discussion of whether it makes sense to pay for a teenager's driving lessons. Many posters said that, as their teen can't yet afford to pay for the car and insurance, they didn't see the point. Just let them do it themselves when they're older if they need to.
I think that's how some women end up not being able to drive. "Later" has a way of being postponed and then children come along and then, of course, everything is put on hold.
I think learning to drive is best done when you're young, because young people are generally less timid. They're accustomed to being taught, to making mistakes, and to being corrected. I think we lose that with age.
For this reason, I will absolutely insist on my children taking driving lessons as soon as they're old enough. I will pay for it. I will pay for them to be on my car insurance, so long as they behave maturely. I believe in doing that in the same way other parents might pay for private school fees.
