I didn't learn to drive until my 20s. Everything took so much longer on public transport. I had to get lifts to work, Wenden I got my first job, as there were no buses there.
I think many people who decry car use are lucky enough to wfh or live somewhere with good links. I also think a lot of mn has no idea about the places where pt assumes you all live and work fairly local, so doesn't link up across counties.
My journey to work is about 20 miles. Takes me about 40 minutes in the car. I do not live rurally. No one I know works near me, so car sharing is out. Not allowed to wfh.
By pt, I would have to get a bus to the train station (if any buses were running at 530), then a train. Then another train, to be in work by 8. Then in reverse. Not sure how I'd get dc to the cm by 7am in any of that though. Or how I'd do pick ups.
Where I live, I can get a bus to one town (10 miles away) every 30 minutes. No buses to another town(11 miles away). One bus an hour to a closer town(6 miles away). To visit parents (12 miles) it's a 20 minute walk to a bus stop, then 40 minute bus ride. I can drive it in 20 minutes.
Like someone upthread said, it's not just getting places but how much time you actually have. Even with 2 adults living here and driving, the kids can't do the activities they want, because of time. Without cars, they'd do nothing during the week. And dc 2 wouldn't be able to theirs at all.
