I work full time, have 2 children, a disabled partner, and live in a rural area. There is 1 bus an hour to the train station.
I can't drive, but I don't have any problems getting anywhere. In an emergency or for awkward journeys I get a taxi. My commute to work takes an hour on public transport, but that is mostly on the train. I get 2 hours work done sitting on a train. Driving would waste my time.
I am attempting to get my household carbon footprint below 8 tonnes for all 4 of us. I think I can manage it, even though I have to fly due to work at least twice a year. One of the reasons I manage it is by not having a car. That is not just about petrol consumption; it is about choosing not to travel as much for leisure and about choosing local leisure activities such as walking that are not bad for the environment; going local is linked to not driving.
It is all very well saying you can learn the skill without then getting a car, but once you can drive it does become a temptation to do it all the time. I do believe it deskills people in other ways. Some people can't organise themselves, because they think they can always just nip back out in the car for whatever it is they've forgotten, and they stop walking short distances. My children walk all over, cycle to friend's houses, and my 8 year old can travel from school to the train station to meet me on my journey back from work; she does this on a public bus on her own, including waiting at the bus stop on her own, paying the driver, behaving sensibly on the bus and getting off at the right stop.
I know people will come on here with anecdotes to the contrary, but the reality is that on average, children walk, cycle and navigate rural and urban environments on their own less now than a generation ago. A major part of that is reliance on the car.
So, to you it is a skill, but to me it is the start of an anti-social addiction.
