It seems the network of roads built in the 40s, 50s and 60s just can no longer be done efficiently.
Of course they can, we have not lost that capability. It's not a matter of efficiency but effectivity. Road constructions of the 1960s are not effective for 21st century traffic demands. Today's level of traffic far exceeds the anticipated level of traffic at the time of construction. Germany sees this all the time, esp. with regards to bridges. Maintaining a road or a bridge to be effective at supporting the original traffic levels is easy but under today's load would require constant maintenance to not deteriorate immediately. Those constructions need to be upgraded which is hard to impossible to do in situ.
Let's take a well-known construction in Germany, the Leverkusener Brücke an der A1. It was originally built in the 1960s for a traffic level of 40,000 cars (and trucks) per day. It was upgraded and refurbished over the decades (meaning almost constant construction work happening) to a level of 100,000 cars per day. It wasn't enough, in 2016 about 120,000 cars crossed the bridge per day. At the same time trucks got about 30 % heavier from 1960 to 1990 and we all know that passenger cars got heavier, too.
So the whole bridge was replaced, which took 7 years, ending in 2024. During that time traffic was rerouted over two nearby bridges in Cologne and Düsseldorf. The Cologne bridge was so badly damaged by the additional load that it had to be partially closed down and now is up for refurbishment or, maybe, replacement. Network effects at work ;)
Anyway, what I'm trying to say is: we are actually better at building stuff than our predecessors but the demands put on our constructions are much, much higher. I don't dare to say if our capabilities have grown as much as the demands require.

As I see it, the US is still riding on the coattails of 1960-s road construction. We should be doing more of it, in fact, not sabotaging it with bike lanes and road diets.
See: https://www.theguardian.com/cities/2017/sep/19/britains-1960... Another example is China, it had bikes as the main transportation mode in many cities, but it abandoned them as soon as they could.
Bikes are a freaking _miserable_ transportation mode. Try biking in subzero temps, or during rain/snow.
> Bikes are a freaking _miserable_ transportation mode. Try biking in subzero temps, or during rain/snow.
Your entire argument seems to revolve around car vs bikes. I am arguing for prioritizing human-centric infrastructure over car-centric infrastructure. This simply means not prioritizing cars above other modes of transit. For urban environments (high density areas) cars are sub-optimal at best and other alternatives like rail, buses, bikes, and trams are simply better. Granted, sometimes cars are appropriate, but I would not use those minority of cases as an argument to justify having a city designed around cars.
> Another example is China, it had bikes as the main transportation mode in many cities, but it abandoned them as soon as they could.
Because Chinese cities now have better public transit. Just look at the size and ridership of their suburban rail and metro networks.
And here comes the propaganda. Why is your (failed, btw) idea of infrastructure is called "human-centric"? What makes it _human_?
I fail to see anything human in dense cities like Tokyo or Manhattan.
> Granted, sometimes cars are appropriate, but I would not use those minority of cases as an argument to justify having a city designed around cars.
If cars lead to better outcomes (and they do, once self-driving is deployed), then why not? Why force people into densified anti-human hellscapes?
> Because Chinese cities now have better public transit. Just look at the size and ridership of their suburban rail and metro networks.
Yes. And once people can, they opt out of transit as well.
Great question. No strict definition as such for me, but in the context of transportation, it loosely means that it must be 'easy' for most people to get from point A to point B, using the least amount of time. Ideally it must must be accessible for all people (so teens without a licenses, legally blind people, or anyone without the means to get a car etc). From a non-transportation context (just adding, not very relevant to the answer), places with no loud traffic noise and just a nice general atmosphere of people around. Think streets with trees, and lively public spaces for people to hang out.
> If cars lead to better outcomes (and they do, once self-driving is deployed), then why not? Why force people into densified anti-human hellscapes?
No one is being forced. If anything, these measures only makes the cities with high urban density more livable for people. The 'hellscapes' have more to do with the housing crisis and zoning laws than transit infrastructure.
Idk why most people think urban density is a problem to be solved (using tech like self driving for eg), because it ultimately always circles back to the fact that density is the only sustainable way for cities to develop and grow in the long run. Even if it is not perfect.
> I fail to see anything human in dense cities like Tokyo or Manhattan.
It would be even more dystopian if Tokyo didn't have a great metro and people had to wait in traffic for hours. Imagine the increased stress, lesser free time, and lower quality of life from all the noise and pollution.
> Yes. And once people can, they opt out of transit as well.
When exactly will most people have the option to opt-out, and how likely and how exactly will it happen?
I also feel like you're arguing just for the argument's sake. If not, we probably have fundamentally different views on what's 'better' and I don't think any amount of convincing will change either of our minds.
OK. Drop 10 random points in a city and then map routes between them using transit, cars, and bikes. You'll find that cars are around 3 times _faster_ than anything else on average. Even in dense cities. I'm going to call this "Cyberax's constant"!
> Ideally it must must be accessible for all people (so teens without a licenses, legally blind people, or anyone without the means to get a car etc).
This means that bikes are right out, they're horribly anti-human. And transit is barely OK.
> From a non-transportation context (just adding, not very relevant to the answer), places with no loud traffic noise and just a nice general atmosphere of people around.
So, EVs are perfect? They are quieter than buses.
> No one is being forced.
People are. By economic forces. Japan is a GREAT cautiounary tale here.
> If anything, these measures only makes the cities with high urban density more livable for people.
No, they make it more inescapable.
> It would be even more dystopian if Tokyo didn't have a great metro and people had to wait in traffic for hours.
Wrong. A Tokyo without transit wouldn't have become so dense.
> I also feel like you're arguing just for the argument's sake. If not, we probably have fundamentally different views on what's 'better' and I don't think any amount of convincing will change either of our minds.
You simply have never thought about the _effects_ of urbanism. Go on, think about it and actually investigate your assumptions.
I got my driving license at the age of 27 and I lived in multiple dense cities.
From some level of experience doing just this all my life, this probably depends a lot on which city, how it's designed, and the time of day you do it at. There's some cities where you can actually get better results I'm sure! And there's some locations where I bet you'll get drastically worse results, especially during rush hour.
I'm really curious where you're living at the moment! And have you considered making counterpoint videos vs NotJustBikes? ;-)
This gives off "I have experience, so I must be right." vibes. There's no reason you can't be, but this goes against what most other urban planning experts and studies have to say.
> Go on, think about it and actually investigate your assumptions.
I feel like _you_ are the one who is only addressing the points that are the easiest to argue using unverified numbers and hypotheticals that would never be practical, just to support your claims, instead of addressing the argument as a whole.
> OK. Drop 10 random points in a city and then map routes between them using transit, cars, and bikes. You'll find that cars are around 3 times _faster_ than anything else on average. Even in dense cities. I'm going to call this "Cyberax's constant"!
I would like to see you prove it. Even if true, no one is actually going from a random point to another random point. Most people have overlapping commute routes, which are anything but random. It is proven mass transit reduce collective travel times, and which is why I mentioned the least amount of time for _most_ people, which you conveniently didn't account for.
> This means that bikes are right out, they're horribly anti-human. And transit is barely OK.
Again I never argued for _only_ bikes, you're dragging your own assumptions and hatred for bikes into the argument. I also don't know why you think bikes more anti-human than cars. Anyway, how is a city that needs cars to get around better than a city that doesn't, better in terms of accessibility? And again, "transit is barely OK", but you conveniently did not mention about the accessibility of cars.
> So, EVs are perfect? They are quieter than buses.
EV buses have all the advantages of being an EV and none of the disadvantages of being private cars (aka more efficient, cheaper, and more accessible). Idk why you would use EV for cars, but not do the same for buses when comparing them (if not just for pushing your agenda). If anything, I would guess the percentage of EV-to-ICE ratio for buses is higher than for passenger cars in most high-density cities (except for the US, ig idk).
> People are. By economic forces. Japan is a GREAT cautiounary tale here.
Economic forces will always end up pushing for more and more density. Pushing for car dependent cities may mitigate this to a point, but it does not create better cities. Good zoning laws have a much higher probability doing that.
> No, they make it more inescapable.
As mentioned, I fail to see how good public infrastructure is stopping a person from leaving a city more than other economic forces, if it is so insufferable.
> Wrong. A Tokyo without transit wouldn't have become so dense.
Great point. It would have become LA. Where your ideas (at least from what I understand about your ideas) have already been implemented. A place known for zero traffic, that consistently comes on top for best cities to live.
I think I am done with this, have a good day bro
It doesn't depend on the city, if we're talking about cities with population more than 2 million!
It's just the result of the inherent inflexibility of fixed routes. If you pick random points, most likely there won't be any direct route between them. So you'll have to do at least one transfer, and this just kills the average speed.
That's why large cities tend to gravitate to the "hub-and-spokes" model. It's simply the only model that works. Look at the transit map for large cities: Tokyo, Berlin, Moscow, Beijing, and you'll start seeing it everywhere.
BTW, it's also the reason bikes work well in Amsterdam.
> And there's some locations where I bet you'll get drastically worse results, especially during rush hour.
For this particular test, it actually doesn't matter that much, due to randomness of the chosen points. It's likely, that at least some routes will bypass the traffic magnets and chokepoints.
> I'm really curious where you're living at the moment! And have you considered making counterpoint videos vs NotJustBikes? ;-)
Yeah, I'm thinking about it.
You know, I'm not saying _anything_ that experts disagree with. And I talked at length with more than one expert, and I had taken a university course in urban planning and demographics.
I'm just not considering the outcomes of urbanization to be positive. And I try to highlight things that urbanists tend to sweep under the rug. E.g. that bike lanes or rapid transit lines do not decrease congestion in most cases (see: https://www.nber.org/system/files/working_papers/w18757/w187... ).
> I would like to see you prove it. Even if true, no one is actually going from a random point to another random point.
Will write a blog post. I've plenty of notes and code for the experiments that I need to organize, instead of doing flame wars. Although sometimes I do hear new arguments.
> EV buses have all the advantages of being an EV and none of the disadvantages of being private cars
Buses are terrible for commutes. They are rolling lifetime destruction machines, with more than one lifetime wasted on commute, every day, for large cities.
They are also terrible for roads (look up the "fourth power law"), and are way too expensive.
Self-driving personal EVs and mini-buses will kill all the rest of transit.
> Great point. It would have become LA.
Or Houston (population 5 million) that still has a faster average commute than ANY large European city.
