Car dependency is an enormous burden on the least well off
To eliminate the car, we'd need to move all of humanity into tiny apartments in super-dense cities, something that isn't practical nor desirable given the current design of cities and the current state of society.
(There's also the issue of 'where does food come from?', and the fact we can't fully automate farming yet, so still need people to live and work where the food is produce, in places where cars are essential)
Oh, and we could live in villages. Like we did before cities grew into such megaliths. That might work too.
There's plenty of land, plenty of places for people that aren't mega-cities. Those of us out here know that. And my commute? Down the hall to my computer.
Put small towns on train lines, the car issue is lessened. Make the shopping districts walkable, again lessened.
I do use a car out here - to get to a city center where I walk from then on. A train or bus would have worked too.
Is that appreciably different from driving to a mall and then walking through it to do your shopping? A quaint downtown square with a hardware store, a grocer, a butcher, and a barber shop is nostalgic but doesn't serve large populations as well.
Pretty different from driving to one mall I guess.
And who goes to 1 mall to do their shopping? I know people who visits three grocery stores and a big-box store to get their groceries. Different places have different stuff, different prices.
I guess that's all part of the car mentality. Takes as long to walk a mall, as drive to another one.
The village/train idea is, make geography meaningful. So you go to a place to do a thing, invest value in the activity.
This is a wildly disingenuous argument! Incremental change is possible. Partial change is possible.
