Its pretty common in poor areas not to drive.
To do lessons, tests, get a car, pay tax and insurance and fix the MOT faults (and I'm lucky I'm a super low risk insurance category so mines cheap for a new driver) cost me nearly £5k before ever even putting petrol in it than that was for a beat up old 15 year old car. It cost more than my IVF.
Millions simply can't afford that on something that is a 'luxury'.
I think circle effects views too:
my DH circle every household he knows has at least one car if not two (lots of medical receptionists, teachers, public servants, people in lower level banking and everyone has college or higher education).
My circle (ignoring the people I met in university) is opposite and virtually no one owns a car (lot of disabled, single mothers, trauma survivors, a few minimum wage retail workers and many are GCSE drop outs, none went to college).
Friends though my 15 year old banger was super fancy, everyone wanted to 'go for a spin'. Oddly I have know 3 that owned SORN cars (write offs they had put in their garden like ornaments) but had no license and they never ran. it was quite a status to say you 'owned' a car (even if it was useless).
In uni virtually no one owned a car either though (I'm sure many of their parents households probably did though)... students aren't very rich either.
