It’s not entirely clear that racial animus was the primary motivating factor. Once civil rights legislation was passed to stop housing discrimination, for instance, there was also black flight, when middle-class black families also moved to the suburbs. It’s also not clear how one is supposed to reverse the effects of white flight; when middle-class whites move into a majority-nonwhite urban area, this is usually con…

I recommend reading Ta-Nehisi Coates on this subject. He's done terrific work on the history of redlining, and also talks about the impact of educated, successful families moving out of historically black neighborhoods.

I'll have to check that out.

> also talks about the impact of educated, successful families moving out of historically black neighborhoods

Yeah, from what else I've read, that is one of the saddest parts of the story. Economic diversity is a hugely important part of a healthy community, and it's pretty uncommon in America.

I think the issue is that public transportation is rarely point to point. A point to point self-driving transportation capsule could be more efficient and be better utilized than public transportation.

Point to point is by definition wasteful. Look at how goods are moved around the globe: it's always hub and spoke because that's what works best rather than an infinite number of dedicated routes. Walk on foot, bike, skateboard, take a bird or lime to a hub and you remove a ton of engineering headaches. You could have the hub to hub route be completely isolated from traffic and pedestrians and many of the highly publ…

The hub-and-spoke model is great for moving goods (and people) between cities, but you'll note that pickup and final delivery are still handled by fleets of trucks. Mass transit is well-suited for routes shared by masses of people with minimal luggage all wanting to transit on the same schedule; point-to-point transportation is needed to handle the rest.

What's really wasteful is using point-to-point transit for a task better suited for mass transit—or vice-versa.

> in a society dominated by cars, there are going to be people without cars that can't easily get to work. You didn't have that problem pre car, "pre car" people would walk or ride horses/bicycles for hours to work. You can still do that now, or go faster by bus. > Cars create sprawl, Growing cities create sprawl. Necessary infrastructure for large cities (yes, you need fire trucks, garbage trucks, buses) as well as…

You'll find that commuting time has stayed fairly stable, we just travel further now. Poor policies and the car create sprawl, not growth. Visit a city that developed pre car, no sprawl. New York was designed with massively wide streets, space for all the things you cite and didn't suffer from sprawl. "parking space for convenient door-to-door transport slightly increases it." Slightly? I can't think of any shop with…

I find the assertion that NYC didn't sprawl somewhat odd. Weren't all the city's parks on the frontier of the city when Olmstead laid them out? (and, in the process, invented the "parking space")

"Slightly? I can't think of any shop with dedicated parking where the shop is bigger than the car park."

WalMart? Home Depot? Kroger? IKEA? I can show google maps if desired, but that's definitely not uncommon in the U.S.

That extra 8ft of frontage is also extra backyard, which many people enjoy. I don't think people choose to live so far apart because they have cars, they live so far apart because they want to, and the car makes it possible. I suspect many would love to live even further apart if they could.

You can get easily insulted for proper choices. Homophobic comments on cycling and veganism are common. I rather believe that we are doomed - that we will destroy nature sufficiently for it to stop producing enough food to sustain us as species - than that we will change.

Humans tend to make changes when there are no other options... and often, after significant damage has been done. Presumably if we "stop producing enough food to sustain us", a lot of humans would die off, but some would survive on the reduced food supply, and make changes to prevent further loss of food. Bear in mind, it's incredibly unlikely that all possible human food sources die off simultaneously. A good exampl…

...until you have a world leader who wonders why we can't use them if we have them.

Today's environmental causes suffer from a credibility problem imposed by the mountains of failed breathless malthusian doomsday predictions from yesterday's environmental causes. I've seen the science and believe it, but the boy who cried wolf was also correct, in the end. Please don't be a credibility problem for tomorrow's environmental causes.

A few decades ago there were hoards of people breathlessly demanding that something be done about the hole in the ozone layer or else we're all doomed. Then we banned CFCs and now the ozone hole is starting to heal itself. But if we hadn't banned CFCs we would have been doomed. The ozone layer actually is really important. Now the danger is climate change and what we need is to stop burning carbon. The lesson from pa…

Except for your extrapolation, that's an excellent example, and it needs to be brandied about a hell of a lot more than it is because doing so builds credibility!

My high school science teacher telling me that we were running out of oil and that gas would be $10 a gallon by the time I entered the workforce did not build credibility.

This is an iterated game. The takeaway is that it's important to be right, important to not be wrong, and important to make sure people know it, not that it's important to lie your ass off (sorry, overstate your cause) in a misguided attempt to help.

4 million a day is full capacity in a city of Delhi’s size? They better start building then https://m.hindustantimes.com/delhi-news/capital-chaos-delhi-...

4M what? Delhi doesn't have 4M cars. It's pretty much bordering on 9M cars, 10M if you include the greater NCR area. The closest number I can find is 31.8L daily ridership in the metro which seems reasonable. The metro had an annual ridership bordering on 1B in 2017-2018. Given a population of 20M, the whole city doesn't travel at once. Add on other factors like - * 30% people (kids, housewives, elders etc etc) do no…

Yes, daily metro ridership

Downvoters, wouldn't you like to know who the avowed racist is? I for one wouldn't want them near by company -- we work with a lot of clients of color, and that's a bad look.

Would you please stop it with the flamebait on divisive topics? The account was an obvious troll. If you want to help combat that kind of thing, why not flag the comment? Other users did, which (a) killed it, and then (b) brought it to our attention so we could ban it. That's how to contribute positively in a case like this. Taking HN threads further into flamewar and political rhetoric is exactly what the guidelines…

Banning unpopular opinions and fostering echo chambers?

> US car manufacturers are doubling down on large trucks and SUVs Manufacturers are building lots of SUVs because this is what people in the US prefer to buy. If manufacturers build tons of subcompacts instead they would have to drop prices and probably sell those subcompacts at a loss. If you wanted to sell more small cars instead you should convince consumers to buy them (e.g., via end user incentives), which would…

Is this really surprising? The benefits of driving a large vehicle are all internal (comfort, safety of vehicle occupants, cargo capacity, range between fueling). The costs, however, are mostly external (road maintenance, emissions, safety of non occupants, space consumed for parking). You'd need to substantially incentivize smaller vehicles to overcome these things, but we actually incentivize larger vehicles (throu…

I think you really touch on the core problem. All the negative externalities are eaten up by the community. The obvious solution is to stop subsidizing cars and instead start teaching the negative externalities. Ready first steps: 1. massively increase gasoline tax. 2. Get rid of all street parking.

I personally would prefer to just ban all combustion engines, but people seem to think I'm insane when I propose this.

If our species is to survive this century we have to get out of our cars. There is no way to sustainably build billions of electric cars- we need to consider that our existing ICE fleet needs to simply be retired and not replaced. Cars are one of the ultimate symbols of the consumption that needs to end if we are to address climate change. Between the asphalt and concrete needed to build infrastructure for them to th…

Public transit generally uses all the same materials, just less of them.

Funny how the loudest voices in these sorts of articles are always from places with temperate weather.

In the midwest you still see people clad head to toe in goretex waterproof gear biking to work in a blizzard. Doesn't matter how the weather is if you've prepared for it.

As a certified goretex biker, there are a few things that are hard to prepare for. High winds and ice or slush can be downright dangerous.
