In my experience, most people really do not understand how fundamentally unsuited cars are to solving urban (or dense suburban) transportation problems. Without really staring at the underlying geometry, it is hard for laypeople to understand that automobile-centric development patterns are by-and-large incapable of producing the kind of human-scale, dense, walkable areas that are (1) instinctively pleasing to be in, (2) generators of economic value, and (3) much more environmentally sustainable than the alternative.

All this being said, I find it hard to fault 'environmentalist' politicians for their embrace of the electric car: politics is "the art of the possible", and the conventional wisdom, at least in the States, does not yet recognize automobile-centrism as a key problem. There are a lot of entrenched interests in favor of the status quo - not just the traditional car lobby (auto manufacturers, suburban developers, oil companies), but the ~half of Americans who live in suburbs, hence having their lifestyle and wealth reliant on cars remaining a dominant form of transportation. If the choice is between gas cars and electric cars (as, for a mainstream politician it basically seems to be), I am at least happy we are moving towards the latter, even though neither are the right answer.

Shameless plug: I recently attempted to visually explain the first issue (why geometry makes cars unsuited to dense transportation) on my nascent blog: https://digital-cygnet.medium.com/a-quick-visual-illustratio...




How many people want to live in dense cities without any means of escape? It sounds miserable to me.

But I live in a really small city (< 250k) and drive maybe 3-5k miles a year (mostly to our cabin in a neighboring state) and bike a LOT. It's kind of ironic I am pretty far from your utopian dense dream yet largely living it.


It sounds like you bike for most of your transportation in your city? That's what "anti-car" people (speaking as one myself) want: to emphasize infrastructure that enables and encourages that. The "anti-car" thing isn't "ban cars entirely in all cases", just "stop assuming everything needs to be car-first at the expense of every other modality".


Yea my point is that if you want to be less car centric, maybe try moving out of the big city. It's ironically easier to obtain that lifestyle in a small city in America than the "walkable urban utopias" everyone seems to desire on HN.


Super obvious response, but it depends on the city. Smaller denser European cities that were not designed, but evolved over hundreds of years from earlier settlements, don't handle car traffic very well and are better suited to walking and cycling (or battery operated scooters). But even larger cities over here work well for walking and cycling because you tend to find lots of bars, restaurants, convenience stores and shopping malls all over them. In my home town, you can't walk a mile without passing a dozen bars, a dozen restaurants and two decent grocery stores.

But it's not just down to city size. Take a city like Provo in Utah. It's not large by any standard, but it's completely designed for cars. It has awful public transport, a grid 'motorway' system cris-crossing it, everything-as-a-drive-thru, lots of unused space, lots of parking lots... If you try walking around it, you'll just spend hours walking past nothing in particular to get to nowhere special.


It seems that everything is way too far apart because it's all separated by huge sprawling parking lots that are mostly empty. 50-70% of the acreage is devoted to cars not even counting the ultra-wide roads and only occasional pedestrian crossings every half mile. These roads usually have speed limits well above 45 mph. The worst examples I can think of are Scottsdale AZ and Irvine CA.

It isn't surprising that so many cars are on the road when just to cross the street you need to walk a quarter mile on average. Then you have to cross the death trap parking lots with zero shade and 120 degree black top.


Here in Europe it's often the opposite. E.g. in Austrian cities you have decent bicycle infrastructure and everything in reach in the cities while in rural areas that's often not the case.

I've been in the US once, 13 years ago, and it was pretty shocking for me to experience the concept of "car centric" in its full glory for the first time. I was at CES in Las Vegas and went to some club one evening with a friend. At some point I left and wanted to walk to the Hotel alone in order to calm down and enjoy the nice climate. Turned out, there was simply no walkable connection between the 2 locations. I couldn't believe it, but - being stubborn - walked anyway, in the dirt along some highway, a bit scared of being picked up by the police, not even sure if walking there was even legal.

Later that week I moved to LA and first saw the endless suburbs of an American city, from the air.

I don't know how representative those 2 places are for the US, but having seen that, I can totally understand why many Americans have a very hard time imagining life without a car.


Mostly only out of American big cities (at least in the developed world), the point is to fix that. A lot of big cities in Europe and East Asia do fine without being car-centric.


A lot of places depend on cars / 2-wheelers beyond American big cities. Based on my first hand experience - big cities in India and Brazil.


You're right, in my zeal I overstated a bit. But among the richest/most developed nations there are the US & a few similar countries (Canada, Australia, New Zealand) where a lot of people drive cars and on the other hand western europe and the reach east asian countries (Japan, Taiwan, South Korea, Singapore) where mass transit (and in Europe sometimes also bicycles) is the main form of transportation in the large cities.


I'm not sure I fully follow "I am pretty far from your utopian dense dream yet largely living it", but I think there are two potential points of disagreement:

1) Living in dense cities is not for everybody, but given that large and (at least pre-covid) growing majority of people in the developed world do choose to live in cities, I think it's safe to say that there is a very sizable demand. For an example of the benefits of density, see [0].

2) I'm not sure exactly what you mean by a "means of escape", but getting rid of cars of course necessitates replacing them with other modalities. If you want to go skiing does it matter to you whether you take a train or a car? Or, for further afield trips, take a train to a car rental far from the city center? (If you mean escape in a literal sense, like "evacuate in the face of a disaster", then cars are clearly not fit for purpose -- if roads can barely handle rush hour traffic, mass evacuation is a recipe for gridlock)

The pre-covid world is kinda over. Density has very clear downsides that have never been more apparent. I don't know how often you do the train + car rental thing, but the friction is much, much higher than driving (especially if you have any sort of gear like you would for skiing). Not everyone wants to be so contricted both in freedom of movement and in living space.


Blaming disease spread on density is kind of a cop out after how we saw the world respond to crisis. Singapore, Taipei, Hong Kong, and most Chinese cities are super dense places that, for most of 2020, I would have preferred to be living in compared to the US.


The success of these cities is due to political action that is unpalatable to most in the west. Hong Kong in particular demonstrates what happens when even vestigial western ideals and the necessary political structures for this sort of action mix.


You can look at San Francisco which did better than most places in the US. It was actually funny to watch tech bro's flee the city for places where the pandemic ultimately hit far worse.


The friction of owning a car is much, much higher than having to care a few times a year on how to carry your skis or sporting gear on a train and renting a car afterwards.

Personal anecdote: I was born, grew up and lived up to my mid-20s in São Paulo, Brazil. It's a city where a car is a basic necessity, much like in the US, public transportation sucks and is spotty, never on time. I owned cars, I loved the frictionless way to get out, getting the elevator out of my apartment, down to the underground garage, turning my car on and driving away, easy. But that car sat idle 98% of the time, I paid road taxes, maintenance, parking spot, etc. for the convenience of having a car ready to go at an instant time.

Nowadays I live in Sweden, I never need a car apart from moving houses or carrying some large furniture. A few times for a road trip here and there, I can just rent a car when needed and I come out on top of expenses still, the peace of mind of not having to take care of a car is another huge bonus.

The pre-COVID world will still exist, cities are a necessity if you want to have good public services, without higher density a city has no way to fund high quality public services.

I would like to know what clear downsides, apart from disease spread, has COVID showed from living in high density cities? And I mean cities like Berlin, Amsterdam, Paris, and so on.


I actually find renting a car offers me significantly less peace of mind, because while I don't care if my own car gets dinged, the rental agencies do. In my experience a weekend car rental costs about 3+ months of upkeep, so for me car ownership is an easy financial decision, even though I mostly walk and bike. I might have a different calculus If I had to pay for a parking spot, but this, along with other premiums for space, I feel is more accurately a cost of high-density living, not car ownership itself.

Some aspects of the pre-COVID world may make a comeback, but hopefully as a society we have realized the omnipresent threat of new diseases is very real. This will impact high-highdensity areas more than low-density areas. It is not just disease spread, but also the policies enacted to limit the spread. My friends in NYC tell me that exorbitant rents for tiny apartments they were forbidden to leave was not particularly enjoyable. Paris seems like an exceptionally bad place to be in 2020/21. Public services are nice when you have access to them and not-so-nice when you are dependent on them and they fail. Often access to services is limited based on economic factors in the best of times, much less in times of stress.


It really depends on where you live and what kind of car you own. My car is very low friction. I can just walk out my front door and drive my car wherever I want to go. Fuel, maintenance, and insurance are all pretty cheap.

By contrast renting is extremely high friction. Even if I reserve a specific type of vehicle in advance that doesn't guarantee that it will actually be available when I show up.


> The pre-covid world is kinda over

I really doubt this is the case. In fact people are placing large bets of the opposite. Just saw in the news that some texas developer is planning a new 23 story commercial building in Vancouver's downtown.

Cities have been the norm since humans started living together. They been been a success despite many, many pandemics. They are not going away.


The US isn't gonna change much. Don't know about elsewhere.

I was in a supermarket last Friday afternoon, in Michigan, and it was "I don't want to be here" busy for normal times, never mind during a pandemic. There were people with no masks and people going through the motions of having a mask and so on. People are moving on before they should! Another couple of months is likely all it will be.


People aren’t always choosing cities, there are greater work opportunities in cities and so that is where people have to go. This was true of factory work in the past when people migrated in droves from farms to work in factories because that was their only option and moving to work in cities for office jobs has just been the latest form of this.

Many people (although not all) would choose space in the countryside over dense in the city if they had a choice. I imagine this becomes even more likely as people have families and begin to prioritise other life aspects over and above work.


I live in Berlin with 2 little kids and have no car. We bike and take transit (including long-range trains when going out of the city). There's plenty opportunity to escape (corona lockdowns notwithstanding).


I’ve never owned a car. But somehow I’ve traveled all over my country and the world. And Australia isn’t small. It’s crazy, I know.


Did you rent one? Are you young and healthy enough to walk/bike everyone? If yes, then your assumption about the world is indeed crazy since not everyone would have the same abilities as you.


What do you mean “no means of escape?”

There are trains, buses, taxis, bikes, rental cars etc.

To me owning a car seems much more miserable!


Cars offer a level of freedom far beyond that of public transport.

That doesn’t mean they are the best vehicle to offer that freedom and electric vehicles will definitely be an improvement over ICE vehicles but in my experience as soon as you’re outside of major metropolitan cities public transport options fall apart and are often incredibly inconvenient compared to owning a car.

Maybe the solution would be to build better public transport systems outside of major cities but to do that requires funding and local governments (in the UK at least) seem to be chronically underfunded so I doubt that it will become a reality anytime soon.


In my experience, currently public transport works really well for high density routes, but no one has managed to solve the low density route issue. Take a bus going towards a leaf node at 10 pm on a week day, and you're often the only one in a huge bus with the driver (that's of course if you're in a place where such a bus exists). Environmentally and economically, that's dreadful, worse than a car. I don't think public transports running at 5% capacity is the solution.

The solution might be full self-driving cars, but we're far from it yet.


Ha, I totally agree with this. I have seen so many of those big empty buses with just 1 or 2 people in them. Perhaps self-driving cars and autonomous vehicles will be the solution to this.


>"To me owning a car seems much more miserable!"

Well you are free not to own it. Nobody's forcing you.

Actually my main mean of transportation in Toronto is bicycle myself (well I work from home for the last 20 years anyways).

I also own car (van actually) and it gives me great and hassle free degree of freedom. If I am in a mood and I often am I can jump in and in few hours be in complete wilderness swimming in some godforsaken lake. Or if I need to grab some heavy stuff and bring it somewhere which happens rather often. And I do not need to arrange / wait for anything. Just get in and go.

So no. Screw that dense car free living. To each their own.


Yes and you can say that a helicopter would offer you even more freedom, but does that mean we should build our cities so that everyone has there own helipad?

Ironically it probably would take up less space than the infrastructure build for cars.

But this is the point made by the OP, essentially for the convenience to jump into your car a couple of times a year and drive to the wilderness without having to walk or take a means of public transport, you require cities to be build around those cars. The issue is you don't directly see the cost associated with it, because you're used to it. The thing is, if you actually had to pay for that convenience (because if we would not have to build the car infrastructure cities could be much cheaper) directly there clearly would be a point where you would say it is not worth it.


Yes, too many people can't bear making anything they sense to be a sacrifice on their part. The solution is definitely to shift the car ownership economic burden more towards car owners instead of everyone. Giant empty parking lots and huge roads are an insane cost with a terrible maintenance story.

I like to think of it as moving away from a datacenter to cloud based solutions. You don't need to buy all that capacity ahead of time anymore just for those short bursts.


>"Yes, too many people can't bear making anything they sense to be a sacrifice on their part."

Sorry but I do not live to make sacrifices for the "benefit of everyone". I already left one country because of that. It was called USSR. And the first thing I did as soon as I could - got myself a car and traveled all over the places on my own.

My small software development company does not use cloud either. Self host and rented dedicated servers. Orders of magnitude cheaper that that cloud. I prefer to feed myself rather then keep filling pockets of FAANG and the likes.


But you are expecting everyone to make sacrifices for your benefit, because non-car drivers are significantly subsidising car drivers. Lets make car cost exactly what they should be then, things like lets make real-estate used for roads in cities go into rental costs for those roads (via taxes, road tolls etc.), lets price the environmental costs appropriately, including the health cost from noise etc. If you still want to pay for your car then, go ahead, but don't expect others to subsidise your living.


How can it be 'complete wilderness' if reachable by car? Isn't there some sort of infrastructure necessary in order to reach it by car which ultimately destroys nature?


Gravel / dirt road and then take canoe to some secluded spot. No one is around which to me is enough to call it "complete wilderness", does not need to be Ellesmere Island. No visible "destruction of nature" either.


Car centric infrastructure forces people to own cars.


And I don't know a ton of people that "buy" cars they can afford, they buy car payments they can afford. I just can't help but feel that breaking that cycle would be a societal good ( for people, sorry automakers).


And I buy used vans. Whet you know might not reflect generic situation.


>"Car centric infrastructure forces people to own cars."

Where? I live in Toronto and I certainly do not feel that I am forced to have a car.


Toronto where the previous mayor removed bike lanes, was caught reading a book whilst driving, and called cyclists "a pain in the ass"? That Toronto?

https://www.bbc.co.uk/news/magazine-17914504

Yeah, that sounds a welcoming place.


I do not give a shit what our previous world famous lunatic said. I just state my personal experience and I ride my bike everywhere nearly every day.


Everywhere where daily amenities are too spread out and the streets are too dangerous for children and old people to cycle on them. That's most of the developed world outside of some very large cities.


And because I do not feel forced it deserves downvote. Fucking thought police.


I would definitely agree with you about the merits of smaller cities, but half the value of density is that "escape" is easier. Driving for a solid hour through nothing but housing estates is not my idea of freedom.

It does depend on your idea of "escape" though. Good trains to beauty spots make a world of difference.


The no means of escape from NYC was what I could never handle (so got a bike, motorcycle, car and eventually just moved out) but there are many people who grew up in big cities for whom the endless concrete blocks is just the normal environment, though I think its kind of sad.


> How many people want to live in dense cities without any means of escape? It sounds miserable to me.

Some 30m people in Tokyo seem to be doing fine.


Doesn’t mean they actually want to be there though.


Nice blog post. It really does come down to just how big cars are and how much space they take up. A car in motion takes up a ridiculous amount of space factoring in stopping distance.


The coming sea change in electrifying transportation will include roads just as much as cars. Right now we are just barely off the bottom of the 'S' curve of transitioning from ICE to electric. But in about fifteen years we'll be near the middle of that curve and that's when we'll realize roads could be much better if the ICE cars where banned. With only electric vehicles the air will cease to be continually poisoned by emissions and then roads and streets will start to move indoors. Covered roads will become practical with electric only vehicles and the majority of those e-vehicles will be a lot smaller than the current average ICE car because electric technologies make smaller vehicles much more practical. The current boom in e-bikes is just the beginning of a major trend to electric smaller vehicles.

A lot more quickly than you expect ICE vehicles will be restricted to the highways and periphery of towns and cities because they'll be too big, heavy and poisonous. In a word they'll become unsafe for urban transport and our cities will become much more healthy and livable.


The trend has already started. E.g. in Germany, some cities prohibit older Diesel engines within city limits.

This has lead especially commuters of low-wage jobs quickly being forced to buy a new, more environmentally-friendly car (and their Diesel car just lost a lot of value in the market), so they have no option other than switch to gasoline engines - which are usually OLDER cars than they used to be with WORSE pollution statistics.

Buying a new car is not affordable to them. Public transportation is a lot better than in the US, but still will not solve the issue completely, and where it is a viable alternative, it's expensive both in time consumption and in money spent.

With a new law that was meant to lower pollution (and the jury is still out on if the goal was achieved, as during the corona crisis, pollution sank overall), we've created worse conditions for the underclass and lower middle class.

This is how you destroy support for ecological policymaking. If you want a better world for yourself and your children, you cannot achieve it by making it worse for others and the present.


The change won’t be for free (even though it probably in the end will save us all a lot of money), and unfortunately, everything that cost money will hit the poor hardest. But that is a problem that is solved with progressive taxes and redistribution, not something that should stop us from saving the environment.


The change won't be for free. But rather than lower the usefulness of cars, make sure new cars have better fuel economies (which directly translates to lower pollution). Within 10-15 years, clunkers get replaced anyways, so a general policy of "by 2027, all newly-registered cars must have a maximum amount of X litres per 100 kilometres" or a ban of Diesel engines outside of speciality markets (military, agriculture, trucks) would hurt virtually no-one (but inefficient car makers, who should improve).

If you hit the poorest, you won't get a ecological paradise, you'll eventually get the next iteration of an autocratic dictatorship (either left-wing or right-wing) - now with the extra support of the industry. No-one needs that.


You clearly don't understand the urgency of the matter. Maybe if you wrote "by 2027, all newly registered cars must have a maximum amount of 0 litres per 100 km". Cars, of all sorts, is fundamentally unsustainable in urban areas. They take too much space, they forces spread, they are too loud, they use too much energy and they polute too much (that includes electric cars). So we have to lower the usefulness of cars to make our cities more useful for the people that live and work in them.

(Electric cars might be the best alternative in rural and even some suburban areas. But they don't belong in a city.)

The reason diesel engines have been prohibited in certain city centers is because they have been shown particulary bad for people's health [0]. That is usually also something that hits the poorest people hardest. Rich people choose to live somewhere else.

Your last paragraph is just non sequitur. If you want to, you can try to explain why you think that would be the case.

>In my experience, most people really do not understand how fundamentally unsuited cars are to solving urban (or dense suburban) transportation problems.

In my experience, most people who are against cars really do not understand how fucking awesome it is to drive a car and how well it works in terms of getting me from A to B in the minimum time with the minimum fuss with plenty of space for my shopping. Nothing else comes close unless you are only going around an uber dense area in rush hour.

Yes, there are issues with cars. I will still rather be stuck in traffic, sitting in my own comfortable indoor seat than riding a bike to work or taking the bus with no guarantee of a seat, nor enough space to sit even if I get it. A little planning and I am at work before rush hour and it isn't even an issue.

If I was to take public transportation it would need to not take twice the time (I measured it from the time I was outside my building to the time I was inside at work), it would need to be far more comfortable and I would need to be certain that there wouldn't be trouble in the bus.

But most of all? I would need to be certain that the people who made the changes were previously happy drivers and are now happy public commuters.

I did just buy a nice bike for the exercise and the ease of parking, but it only makes sense for short journeys to dense places where parking is the major issue.


The key driver of our apparent disagreement is likely the definition of "urban (or dense suburban)" in my post. There are plenty of places and use cases for which cars are magical things, whisking you from place to place with no effort and a minimum of cost. However, the important things to understand are:

1) Many countries effectively subsidize cars over public transit in ways that are non obvious (not charging for externalities, minimum parking requirements, huge comparative investment in automotive public works), so your accounting of the costs you see (insurance, gas, depreciation) will likely underestimate the true societal cost.

2) The problem that cars seem to solve (getting around a sparse world) is also _the problem that cars cause_ (sparsification). If you have to drive three miles to get to the grocery store, you could think "thanks cars for making this drive easy", or "boo cars for making this drive necessary". In the city I live in there are 3 grocery stores within a 10 minute walk of my apartment.

3) Some people truly do prefer the spread out, population-sparse lifestyle enabled by cars. But some other people truly prefer the dense, walkable urban lifestyle that, as I have mentioned, cars seriously disrupt. The damage comes when people in one group try to force the other to adapt to rules that make sense in their preferred environment (e.g., if Urbanite A wants to ban cars while Ruralite B wants to put highways through the urban center so she can get to work via car). I tend to side with the Urbanites on this issue at present, because it doesnt take much to see who has the upper hand in American cities right now. (viz: Rober Mosesization of most major American metros in the 60s-80s)


The issue boils down to roads and parking more than cars. Trees need sunlight, but cars don’t so roads work just fine segregated below street level away from pedestrians and inclement weather. It sounds expensive, but work out how expensive NYC’s above ground road network costs both in terms of land value and ongoing property taxes and you see just how pricy cheap roads end up.

Go 3D to segregate N/S traffic from E/W traffic thereby eliminating traffic lights and things really pick up. Of course it’s much easier to blame cars, but counties only have so many people you can actually build enough infrastructure to solve the root issues.


lol ok elon



Love the explanation. But what about adding some underground parking?


It's a fix but a costly one. An underground car spot costs in the tens of thousands and so this ends up boosting the price of housing in addition to making construction more complex and time consuming.

As well there's the environmental impact. Concrete creates a lot of CO2 and we actually need to use less of it going forward.


Issue is, cars are incredibly convenient.

Need to get somewhere in the suburbs? Carry large items? Go in the nature for the weekend? Any route that's not been anticipated by the central-public-transport-planning-committee is probably way better done with a car latency-wise.

Above a certain income threshold, it'll be really hard to convince people to ditch their car completely. You might get away with reducing car footprint from one per adult to one per household. Any dense development should have some sort of underground parking planned for it. Then it makes it much easier to get rid of on-street parking and convert the space into safe cycling infrastructure.


It's no real argument that cars will always win the day on the edge cases, though the real question is whether we should be designing our cities to accomodate the edge cases for the majority cases. The majority of transportation uses are much more mundane and can be well served by active transportation and public transportation.

For example creating a bus route to the base of the mountain so that hikers and snowshoers can access the wilderness is a big win for the public at large, but nonetheless there will always be a group of enthusiasts that want go on a further flung mountain hike, and they'll need to use a car to get there. Doesn't mean it wasn't a good idea to create the infrastructure that accommodates the bigger group.

Building big expensive concrete car lots, assuming everyone has a car, is an example of building for the edge case. In Vancouver, a city that has done not a bad job of building protected bike lanes, there's data out now to support that the parking lots that it has mandated in new apartment buildings are in fact overbuilt, under utilized and part vacant!


> whether we should be designing our cities to accomodate the edge cases for the majority cases.

Edge cases will always need to be accommodated. That's one of the foundation of engineering and good design.

> In Vancouver, a city that has done not a bad job of building protected bike lanes, there's data out now to support that the parking lots that it has mandated in new apartment buildings are in fact overbuilt, under utilized and part vacant!

In a city that's famous for having real estate sold for investment purposes and not actually occupied? Shocking!


If they started to charge the same for parking and street space as for any other property in places like NYC, the problem would disappear rapidly.


Is parking possible on both sides of each apartment block (re: your blog post)?


Thanks for the comment -- yes it is, but all sides also have more apartment buildings on them so it doesnt change the analysis. I probably could have explained that better in the post
