I know the demographics around here, so I know everyone’s just going to put “nothing lol”, but please understand what I’m asking first.
I’m physically incapable of driving a car. I stand to gain immeasurably from a world that didn’t assume everyone owned one. Having loved-ones with respiratory issues aggravated by car exhaust has made me very aware of the health issues surrounding the burning of fossil fuels, and having to navigate sidewalkless suburban stroads on a regular basis and juggle poorly funded public transit has made it very clear to me that pedestrians are second class citizens. I could go on and on about the mess cars have made of urban planning, and the number of jobs I couldn’t take because they required driving, but I digress.
In short, I hate cars just as much as the rest of you. But I’m also conscious that a lot of other people feel differently. What does widespread car ownership enable that would be difficult or impossible otherwise?
As an American I’m familiar with the cultural aura that surrounds the automobile. One of the early episodes of Mythbusters explained this pretty well while digging into the folklore surrounding a particular car-related urban legend. Cars represent freedom and self determination, two qualities highly prized in American society. You can go where you want when you want, without relying on schedules and routes mandated by public transit[1].
Looking at more tangible things, I suppose hauling a bunch of stuff from point A to point B would be hard without a car.
But what else am I missing?
Ignoring the fact you can only go where there are roads, and someone has to build and maintain those roads. ↩︎


Whole sections of the country that are zoned for suburban single family housing would not exist as they are today. Not because they’d be illegal or anything, but they’d be incredibly unpopular if most people didn’t own a car, which is needed to basically get to or from a suburban neighborhood.
I understand the question to be something like: what happens if a majority of people are absolutely dead-set unwilling/unable to own a private automobile. And I think the immediate answer is that suburban neighborhoods cease to exist, at least at the current density levels. Either a neighborhood must densify so that transit options make sense, or they must aim to become rural living. This also means that things like suburban schools either turn into walkable urban schools, or into small one-room rural schools.
I don’t actually think rural living will go away, because the fact is that the grand majority of people – USA and abroad – do not prefer rural living. The 18th, 19th, 20th, and 21st Century trends are that people tend towards urban areas, where services and jobs exist. That said, there will always be people that want to live in the hills on 20 acres, and therefore need an automobile. And it’s certainly sounds appealing to some, myself included. But that has never been the majority, so if a majority of people refuse owning an automobile, they will also mostly refuse rural and suburban living.
There is no plausible situation where over 50% of people willingly decide to: 1) not own a car, and 2) live in a suburb or rural area. This is from the fact that all other modes of transport into a suburb or rural area are either: 1) nonexistent (eg metro rail), or 2) ludicrously expensive (eg Lyft, or transit with 15% fairbox recovery) if the cost was borne by the people living there (as opposed to being subsidized heavily by other taxpayers… Ahem, America).
Edit: some more thoughts: standalone strip malls would also change character, because the smaller ones that aren’t on a rail or bus corridor would be undesirable commercial real estate. If they still exist, they’ll likely be integrated into housing, so as to become the #1 most convenient option for people living there. Captive audience, indeed.
But larger strip malls and shopping centers actually might florish: they usually have enough stores and services that transit already makes sense. Indeed, shopping malls are actually really good transit center locations. But instead of giant parking lots, there would be housing, because why not? People who reject cars have every reason to live next to, or on top of, a mall: fully pedestrianized, air conditioned, lots of stores and dining options. Some places even put schools and post offices in their shopping malls. I would also expect that dwelling soundproofing to get better, because the paper-thin walls of American homes and apartments are awful.
In this way, malls are no different than casinos, cruise ships, and downtowns: a small island of paradise to visit, and is distinct from home. Malls will still exist after cars, the same way that Las Vegas exists in the middle of a desert: it is a big enough anchor that draws people.
