I used to work for a Belzer family (the Chassidic sect named in the article). The wife drove, though not often - she didn't need to. There wasn't an eruv at the time but the wife also went out on Shabbat if somebody else was around to mind the baby (because pushing a pushchair on Shabbat in a public place with no eruv is a no-no - yeah, I know it sounds bonkers, but it makes sense to those who live by those rules). The wife also felt able to have a go at the husband if she thought he'd got something wrong.
When my mother came to collect me to go home one weekend, the DC were all over her and my mother came away impressed by what a lovely woman their mother was. I lived in their house for a summer, looked after the DC (lovely kids), and kept in touch for several years afterwards. I had proper conversations with both of the parents - the husband as well as the wife. As a family they used Yiddish a lot, but conversations around me, about me etc were always in English (except one phone conversation where I knew I was being talked about and understood enough Yiddish to understand it!: 'She's so good with the children.') When I left I had taught the DC the joy of a fried egg with an intact yolk - 'bubble eggs!' - which the mother, who had always made omelettes, was now obliged to cook for them.
It's true that it is very hard to leave that kind of life, after that sort of quite sequestered upbringing, and those who do get out tend to see themselves as having 'escaped' and can be pretty angry about it. That said, the couple I worked for both seemed pretty happy with their lives and each other, and I have heard of people who have opted into it, as adults.
I'm not Jewish, by the way. Those are just my own experiences.
