The difference is public transport, ease of transport, etc.
Distances may be short, but when there isn't a cheap "every 5 minutes" bus or underground train, even short distances become a problem. A few miles by car can take a long time at busy times of the day with nose to tail queuing traffic a daily occurrence. Just going a few miles by public transport can mean studying timetables which is necessary when some trains/buses are only every 2 hours, don't run in the evenings, don't run on Sundays, etc.
That makes people more insular. Add into that recent (last few years) problems with train unreliability, then more recently, public transport strikes and staff shortages, etc., and even relatively small journeys previously fine by public transport are now problematic.
For a job I used to have, just 20 miles from home, I had to drive because public transport would take 2 hours and I'd have to set off at 6am to arrive there at 8am - there was no public transport to get me there closer to our 9am start. Same coming home, for a 5pm finish, the train left at 6pm and got me home for 8pm. Just 20 miles! Driving was fine until the Winter, when roads were awful with flooding, blocked by snow, etc. And, no, I didn't live nor work in small villages - these were significant towns, the closest next to each other, just with poor transport links between them.
I don't think that people living in areas with a comprehensive, plentiful, cheap, public transport network, can even start to comprehend what life is like outside those big cities, when every journey needs to be planned carefully, rather than just hopping on the next train/bus that you know will be along within 10 minutes or so, and that will contact with other routes etc., likewise with just a 10 minute or so wait.
For my son to get to school, just 5 miles away, he had to leave home at 7.30 because it was an hourly bus that went, literally, everywhere (no direct buses), that took forever, and then inevitably got stuck in the grid locked one way system. If he'd got the 8.30 bus, he'd never get there before 9.30! Just 5 miles. Then you wonder why people say "around here" as meaning just a few miles! That's the reality when transport is crap!
