I think as people have implied, this does differ hugely depending on where you live. As I’ve mentioned on the EV thread, we went car free for nearly 5 years, until last September. However, we live in London (Newham) & I think it’s a lot easier in a city. I commute to work by bike (11 miles each way) and on the very rare days that I don’t cycle, I can get on the train. We do a huge amount of our shopping for small bits and socialising locally and we have been having our main grocery shop delivered for years, plus we get a veg box delivery. During the time with no car, we occasionally borrowed one from my father-in-law and probably hired one about 3 times for holidays. Our main reason for going back to having a car (Nissan Leaf EV) is down to ageing parents living outside London and having a dog (travelling by train with a dog and luggage is not a friendly experience). Having said that, the car still sits around a lot. It doesn’t get driven during the week (I’m thinking about getting a pool of local friends together to do a car share) and 99% of the time it’s used to go out of London - i.e. I don’t drive in the city. I would say that for most of us living in cities, with more and more car share schemes coming in, it is entirely possible to live car free (probably more so if you don’t have kids - but I know several local families that don’t have cars).
My sister on the other hand, lives in Wiltshire and travels to work in Cheltenham. The roads are not friendly for cycling where she lives (unless you’re an experienced road cyclist - you will see plenty of lycra out there) and certainly not suitable for riding with her 10 year old son. So… whilst I’m persuading her to go EV on her next car, she is my example of the impracticalities of car free life outside big cities.
