As I understand it, that’s not _strictly_ true. 17% live in “rural” areas, but this includes towns and villages in rural areas. It’s 8% for “rural village and fringe” [0], or much less for actually outside of towns and villages. Unless you have other stats to share?
I have lived in several towns and cities in the UK.
The problem is that even in reasonable sized towns not having a car is very limiting. The solution is much better public transport - more frequent is the big thing. That is the difference
On the other hand I did not have a car in London (which has very frequent public transport until quite late in the night), nor in Manchester (not as good, but OK) until I had a child. It was no problem. paying for the occasional taxi and hiring cars for trips when needed was a lot cheaper than running a car and more convenient too.
There is no way to provide a public transport service from the village 9 miles away with 4,000 people to my village of 150 at 2145 on a Friday night. It would have to literally be a taxi going out and back to transport one person.
