[jdkardia]

I would beg to differ. 3 season biking is easy as pie, and 4 season with just a little effort. there was only maybe a month out of the year I couldn't bike to work in Minneapolis or Chicago, all it takes is infrastructure and the right gear.

[jupp0r]

True for you and me, insurmountable inconveniences for the average person.

[jodrellblank]

As easy as pie, all it takes to bike to work is all the tarmac and smooth roads of a car world, all the parking space of a small car world, all the maintenance of a small vehicle, and a car/bus/taxi/train system for when you can’t bike, and their infrastructure, parking and maintenance.

Do bikes have the largest amount of unmentioned externalities of any form of transport?

[dahart]

> all it takes to bike to work is all the tarmac and smooth roads of a car world, all the parking space of a small car world, all the maintenance of a small vehicle

You are just joking, right? You’re exaggerating by an order of magnitude, you can literally fit 10 bikes in the space of a small car, on the road and when parked. You think bike maintenance is the same effort as car maintenance? I’m baffled by this claim, and I maintain several bikes and several cars. Cars are much harder, much more expensive to maintain, and require far more resources. Bike maintenance is something most riders can do on their own, while car maintenance is something people take to a shop.

> Do bikes have the largest amount of unmentioned externalities of any form of transport?

What on earth are you referring to? Are you comparing a few sidewalks and bike lanes in select metro areas to the 3 million miles of paved roads in the US? Are you suggesting the 1-2 ounces of oil I use on my bike chain per year is somehow worse than the average 2 metric tons of gas and oil used by the average car in a year? Are you including pollution in your list of externalities? Are you including accidents and fatalities in your calculation? I’m confused, I really can’t think of a single unmentioned externality where bikes don’t compare favorably to cars by a very wide margin.

So, it seems like the answer is a really clear and obvious no, there are other forms of transport with externalities so much larger than bikes that it makes the mere suggestion seem pretty absurd. Examples include but aren’t limited to: cars, airplanes, and cargo boats.

[jodrellblank]

> You are just joking, right? you can literally fit 10 bikes in the space of a small car, on the road

You are just joking, right? A Fiat 500 is 3.5 meters long and 1.6 meters wide. No way can you "literally" fit 10 bikes being ridden on the road in that space - or even 3. Parked, you might be able to fit 3 if they're staggered, but if you're going to tell me you can double-decker it, you won't also fit the stairs/ramp/elevator mechanism in that space as well.

> You think bike maintenance is the same effort as car maintenance?

You take it to a shop, drop it off, and leave it there, then get it back later? Yes, that sounds about the same effort. Except a car usually needs servicing and is still drivable, a bike is probably punctured or chain snapped and unusable, making it more hassle, and if you decide that means you have to do it yourself, more effort. Everyone remember how fun it is to take a bike wheel off and run it through the bathtub to identify the location of a puncture, yes? Never spent that much effort on taking my car to a garage.

> Bike maintenance is something most riders can do on their own, while car maintenance is something people take to a shop.

You've gone from "baffled by this claim" to "most people spend more effort on bike maintenance than car maintenance" in the space of a paragraph. No comment.

> What on earth are you referring to?

I'm referring to the things I said. If you didn't have paved roads made for cars, you would need to build them for bikes. You wouldn't need to build them for walking. Bikers never ever mention this, it's a kind of parasitism on the car infrastructure - a cost that bikers don't consider. If there were no cars, but we needed to upkeep hundreds of miles of tarmac roads, bikes would need to be taxed hugely. It's an externality in the sense that bikes need it, but aren't paying (directly) for it, and are offloading the cost onto car drivers (who currently need it more and do more damage to it).

> Are you including pollution in your list of externalities?

No I'm not including the cost of container shipping enough bikes for 500,000 people from China, or the cost of digging up the iron ore and making the steel and carbon fibre to build them, or the trash heaps where hundreds of thousands of bikes rot. Good point though, neither do bike enthusiasts.

> Are you including accidents and fatalities in your calculation?

The kind where a big heavy fast moving metal lump collides with a soft squidgy easily damaged slow-moving pedestrian? I'm not including those either, but I am against bikes being allowed anywhere pedestrians are, so let's add that in as well.

> I’m confused, I really can’t think of a single unmentioned externality where bikes don’t compare favorably to cars by a very wide margin.

Neither can I. That's a totally cherry-picked comparison because it's like saying "being stabbed compares favourably to being shot by a very wide margin". There's no unmentioned externality where walking doesn't compare favourably to bikes by a very wide margin - in a place which is designed and built for humans walking -- which all places should be because humans are more important than vehicles. Walking needs less tarmac, less machinery, less maintenance, less money, is more accessible to people of more abilities, takes less parking space, less infrastructure, causes fewer accidents, places fewer restrictions on clothing, has lower environmental cost, lower pollution, less waste, doesn't need helmets and high-visibility clothing and bike-locks, doesn't need insurance and breakdown recovery and loan-cars...

> So, it seems like the answer is a really clear and obvious no, there are other forms of transport with externalities so much larger than bikes that it makes the mere suggestion seem pretty absurd.

Cars pay for roads in terms of fuel taxes and vehicle taxes. Bikes don't pay for either. Cars often pay for car parks, bikes often use sidewalk, or car parks. Cars pay for accidents with mandatory insurance, bike riders are uninsured. That other things are worse was not my point, my point was that bikers gloss over needing roads and the cost of that, car drivers don't.

[dahart]

Look I don’t know what has you so triggered and angry about bikes, but your hyperbole and exaggeration is undermining your arguments, you’re making your points weaker by trying so hard to prove your point. A good example is framing fixing a bike flat to be more effort than taking your car to the mechanic. Fixing a flat takes roughly 5 minutes if you’re slow, which is less time than it takes to drive to the shop (by approx. 1 order of magnitude), and a lot less money (by approx. 2 orders of magnitude). I know it happens once in a while, but I’ve never snapped a chain in my life. On the other hand, I have had a car engine blow out, more than once.

It’s just us here; acting like a bike is soooo hard to deal with isn’t going to convince me, since I know how much effort bike maintenance takes and how much car maintenance takes. I know from experience that cars are the bigger drain on time and money by many multiples. Pretending otherwise is just ensuring I have more reasons to discount what you’re saying.

> A Fiat 500 is 3.5 meters long and 1.6 meters wide. No way can you “literally” fit 10 bikes being ridden on the road in that space - or even 3. Parked, you might be able to fit 3.

Standard bike rack spacing is 12-16 inches. Mine is 14 and fits mountain bikes side by side. I’ll give you a generous 15 inches, in which you can comfortably fit 8 bikes in 3.5 meters. 1.6 meters wide is a tad narrow, but many full size adult bikes come in at just over 1.7 meters long. You ungenerously picked one of the smallest cars ever made to attempt to prove your point, but I’m happy to concede that you were wrong by 8x rather than 10x. If you picked a Honda Fit, which is on the small side of small cars, then 10 bikes actually do fit in it’s 162 inch length.

Lanes aren’t 1.6 meters wide, they are wider, and bikes don’t need to be spaced out as much as cars. The throughput can be much higher than 10x due to slower speeds and the higher density in both directions, sideways and front to back.

It seems like you decided the outcome before you thought about this very carefully.

> No, I’m not including the cost of container shipping ...

There’s a lot of snark in your answer, but you fail to acknowledge that there’s no winning the comparison against cars, which is what I was talking about. Whatever the costs of shipping and materials, cars are 20-40x the mass of bikes.

Hey, I agree with you that walking is cheaper than bikes in all ways, and I surely advocate walking. I don’t get your rage over bikes though, they’re a huge improvement over cars, and they are not otherwise causing problems relative to walking.

> my point was that bikers gloss over needing roads and the cost of that, car drivers don't.

One tiny little nit you seem to have overlooked: walkers need and use sidewalks too, so for the one “externality” you’re considering (while selectively ignoring the larger and more important ones like pollution, oil & gas, and accidents) pavement is an externality for walking too. You could claim walkers don’t need sidewalks, but bikes don’t really need sidewalks either, plenty of bikes will ride on dirt paths comfortably.

[dahart]

> Hey, I agree with you that walking is cheaper than bikes in all ways, and I surely advocate walking.

I'm going to back-pedal just a little bit. Pun intended :P I love walking as a means of transport, but...

Biking is the most energy-efficient form of transportation by a long way. https://www.exploratorium.edu/cycling/humanpower1.html#:~:te....

That answers a bunch of the questions asked in this thread. Another relevant answer to why biking is useful is that it extends the range of accessible daily activities around 10x compared to walking. You can bike further than you can walk in a given period of time.

So one of those hidden externalities you like to account for @jodrellblank, of walking vs biking is that walkers require more food consumption to sustain a daily commute of a given distance compared to bikers commuting the same distance.

[jodrellblank]

This is the kind of thing I'm talking about with unmentioned externalities.

Biking is the most energy-efficient form of transportation, if you ignore the fact that to get such a result you have to make bikes and make steamrollers and concrete mixers and tarmac and roads first.

> Another relevant answer to why biking is useful is that it extends the range of accessible daily activities around 10x compared to walking. You can bike further than you can walk in a given period of time.

But not 10x compared to walking + bus or walking + taxi or walking + train, and not without added inconvenience of biking; and also not if you've built your environment so plenty of daily activities people want are close enough to comfortably walk to.

> So one of those hidden externalities you like to account for @jodrellblank, of walking vs biking is that walkers require more food consumption to sustain a daily commute of a given distance compared to bikers commuting the same distance.

And walkers require paying more taxes for the infrastructure to subsidise bikers.

[jodrellblank]

Any argument which makes bikes better than cars, makes walking better than bikes; you keep ignoring that and diverting back to "bikes are better than cars". Yes bikes are better than cars. Walking is better than bikes.

> Fixing a flat takes roughly 5 minutes if you’re slow.

I googled "how long to fix a puncture" (it's a long time since I had to do that) and CyclistResource.com[1] says puncture repair glue takes 5-8 minutes to dry. My proverbial mother is not going to have her puncture fixed in the middle of a pedestrian street in 5 minutes, and when she ends frustrated and with chain oil on her tidy clothes and muddy wet hands with nowhere to wash them and I call her "slow" that will earn me a proverbial slap. Assuming she even knows what quick release is, and can find the tiny inconvenient weight-optimised tyre levers which she's sure are in her bag somewhere under all this stuff she actually cares about. It takes 5 minutes maybe true for a certain kind of bike enthusiast mechanically interested person, I doubt it's true for a majority of the population.

Going to a garage is less effort even if it takes more time. That's usually the trade off - longer, less effort. But even so that's you redirecting to cars away from walking. Nobody has to carry tyre levers and a Nike Air pump to fix even their fancy airwalk trainers, let alone their ordinary tidy going-out shoes.

I'll concede that you can pack more bikes into a parking space than I counted for, but even your estimate of approx 10 bikes per 4 meters means a city like Amsterdam of 800,000 people would need a row of bike parking 80km long just to cover a quarter of its population having a single place to park their bikes. No matter how multistorey that gets, by the time those people can park in many places (at home, work, green park, shopping, entertainment) it's a lot of city space for a benefit of a minority of people. And yes, before you say it, cars are much worse.

> It’s just us here; acting like a bike is soooo hard to deal with isn’t going to convince me, since I know how much effort bike maintenance takes and how much car maintenance takes

I also know how much effort bike maintenance takes, which is not a /lot/ but is more than I can be bothered with for the few situations they have value in. If a journey is short, walking is more convenient. If a journey is long, cars are more convenient. If there's something to carry, cars are more convenient. If there's a destination I need to go inside, walking is more convenient. If there's multiple people to go with, walking or driving are way more convenient. If there's a chance plans will change and I'll get a lift back or we'll meet up with other people, walking and cars are more convenient. Bikes only win out for people who want to ride a bike for the purpose of riding a bike (fun, exercise) or for people who have a short-car-journey distance to travel with little to carry, alone or with another biker, but don't want to use a car (for environmental, cost, or idealism reasons), or a blend of the two (a single digit mile commute they'd rather not drive).

> I don’t get your rage over bikes though, they’re a huge improvement over cars, and they are not otherwise causing problems relative to walking.

They are an improvement over cars. They aren't a huge improvement. Instead of a roof, you have to change your clothes and carry a change of clothes with you. Instead of a trunk you have to arrange your life around the limits of a bike to carry less stuff. Instead of an engine to go any distance comfortably you have to pay attention to distances and hills and how sweaty you are willing to get. Instead of freely wearing what you want, you have to wear clothes suitable for biking. Instead of having a lockable metal storage you have the inconvenience of not having that but still needing to carry bike things (helmet, lock, toolkit). Instead of being comfortbly on a sidewalk as a pedestrian or on a road in a car, you have to be annoyingly (maybe illegally) on a sidewalk or in danger on a road full of cars, or be lucky and go a diversion in the few places there happens to be a bike path.

They're a "huge" improvement over cars only if you take away all the conveniences of a car, and offload those things onto the person while pretending you aren't doing that.

> One tiny little nit you seem to have overlooked: walkers need and use sidewalks too

Walkers should get sidewalks without bikes. If I say you walk at 4mph and bike at 6mph you'll probably tell me you can average 20mph on your bike. If I say bikes don't mesh with people, and are an accident risk, you'll say bikes "use sidewalks too" and point to people sedately biking at 3mph among strolling pedestrians. If you're biking at a speed that's safe /and not annoying/ to pedestrians (i.e. not weaving between people, making them jump out of the way) then you're going slow enough that you're as well off walking. If you're going faster in a way that only a bike can, you shouldn't be on a sidewalk and need a dedicated concrete place to cycle fast.

All 800k people in imaginary Amsterdam pay taxes for sidewalks because all 800k people use them. All drivers pay fuel and road tax, all cars use roads. Bikers don't pay any special tax for roads or bike paths, which means the minority of bikers are subsidised by everyone else. It's not hyperbole, exaggeration, hatred or snark to point out this kind of thing.

> You could claim walkers don’t need sidewalks, but bikes don’t really need sidewalks either, plenty of bikes will ride on dirt paths comfortably.

Leaving a chewed up muddy plowed mess for everyone else to walk on. Walking on cobblestones is easy and comfortable, riding on them needs suspension and arms that don't mind juddering. But what I'm really claiming is that taxing 100% of the people to make sidewalks that 100% of the people use is fine. Taxing motorists for roads which their cars use is fine. Bikes get the benefit of lots of paved roadway, which they approximately need, without explicity paying in any way. If there were only sidewalks bikes would clash with people. If there weren't roadways, bikes would need them to be invented. If my mother needed a full suspension mountain bike to go to church on, she probably wouldn't. If cars vanished, bikes don't provide anything like the income for the upkeep of the roads left behind by cars if cars vanished. If instead you move to a model where bikes need hundreds of km of bike paths weaving through the city seperate from sidewalks, and then you move to a model where bikers are the people who pay for that, bikes will become a lot less desirable.

Even the limited convenience and usefulness bikes have (which is nonzero) is enhanced by leaning on a car-culture and would struggle hard to stand on its own merits.

Did something bad happen to you relating to cycling? You’re struggling so hard to paint bikes negatively, exaggerating so much about minor and insignificant problems, that I can’t help but assume a cyclist must have collided with you or there’s someone annoying in your life who really into cycling. Do you have a physical condition that prevents you from cycling? Do you lean libertarian and have a problem with taxes for things you don’t use?

I still don’t get your angle whatsoever. Every single thing you claim to want is advanced considerably, and we get closer to walking culture, every single time someone rides a bike instead of a car.

> Any argument which makes bikes better than cars, makes walking better than bikes; you keep ignoring that and diverting back to "bikes are better than cars". Yes bikes are better than cars. Walking is better than bikes

I responded to your comparison between bikes and cars. My argument is that bikes are better than cars. So we are in full agreement. I’m not arguing about walking, I said twice already I’m in favor of walking.

> Walking is better than bikes

That depends entirely on what you mean by “better”. Bikes have a larger range, shorter travel times, and are more efficient. Walking is IMO more pleasant and a slightly safer, but not as functional for traveling more than .5 miles or carrying any cargo with you, even as small as a laptop.

Personally, I think it does a disservice to both bikers and walkers, and to the causes of human designed cities and pollution reduction, to fabricate drama by pitting bikes against walkers as if they're somehow in complete opposition. Bikers and walkers are 99.9% on the same side. I love doing both walking and biking. As a biker, I see people advocating for walking spaces and even bike-free sidewalks as a good thing that helps me. As a walker, I see people asking for bike lanes downtown as a good thing that helps me. You say you don't want bikes on your sidewalk, yet complain about how bike paths are paid for... you do realize that dedicated bike paths get bikes off the sidewalk, right?

> Going to a garage is less effort even if it takes more time.

For someone who brought the concept of externality to this thread, you’re actively trying to externalize time to exaggerate your claims. Cars are more expensive, and money requires time. You can’t count only the travel time to the shop while ignoring the extra time it takes to earn the money to buy & repair your car.

> Walkers should get sidewalks without bikes.

Irrelevant to our discussion, but I happen to agree.

> [in Amsterdam] Bikers don’t pay any special tax for roads or bike paths

This isn’t true, you are making assumptions, making things up. Citizens fund Amsterdam’s bike infrastructure. Not walkers, not drivers. Citizens.

In the city I live in, bike paths are being added by referendum. They are voted on and the funds come from multiple tax sources. I’m paying for the bike infrastructure I enjoy, and the majority of my fellow citizens are asking for improved bike infrastructure.

You are harping up a storm on a complete and total non-issue. Who pays for bike paths is not a major problem anywhere. And if it was a problem, it would be a great problem to have, because it would mean people are biking instead of driving.

[labawi]

Have you been in a place where lots of people ride bikes?

A small car world would be 100% -> 60% resource reduction. At reasonable scale, bikes are at least a 100% -> 10% reduction in all mentioned 'externalities' or should we say resource use, or 10x capacity for same resources, except for road size at maybe 3x, but still more than 10x on cost.

Public transit would grow (no need to fit all cyclists), but that should actually be a net benefit.

To comprehend the difference in scale, view images here [1]. Half as many cars wouldn't fit, even if they covered every cm of the image.

[1] https://biketoeverything.com/2018/12/18/bicycle-infrastructu...

[jodrellblank]

> A small car world would be 100% -> 60% resource reduction.

You're missing the part I replied to which was about bikes being usable 11 months of the year. If you need all the car infrastructure for 1 month, plus the bike infrastructure, that makes it overall worse, not better.

But discard that, if biking is a 60% reduction, then a walking+train world would be way more.

Your link talks of a train station building a 12,500 bike-parking garage. For comparison the busiest train station in the UK (Waterloo) has 250,000 people using it every day. Note that the pictured bike parking in Amsterdam takes up the space of two of the large multistorey hotels next to it, just to store metal, but pushes actual walking humans two hotel distances further away from their destination just to walk past unused metal storage.

Bike parking, like car parking, is a non-place in the sense of https://newworldeconomics.com//place-and-non-place/ it's not somewhere anyone wants to go, or a place where anything happens. Scale that bike parking up to 100,000 people and it would be an enormous amount of physical city-center non-place. Now count that you have to park those bikes at both ends of every journey - bike parking at the supermarket, at the clothes shops, at the pubs, at the apartment buildings - and instead of a small, dense, walkable city center, you're now measuring the total area devoted to non-place metal storage in square kilometers, and inconveniencing everyone with kilometers more walking every week just to cross the distances taken up by mega bike park bloat.

This picture is Shinjuku in Tokyo, the world's most populated city, near the world's busiest train station: https://newworldeconomics.com/wp-content/uploads/2017/01/shi... - can you imagine that street being as pleasant with 2,000 bikes barelling down it at 2x walking speed and every one of those eateries having 5-20 bike parking outside?

And there's no chance those 12,500 bikes would fit on the trains, how many bikes fit on a passenger train, maybe 15 or so? Bike+train means most people can only bike on one side of any train journey.

> Public transit would grow (no need to fit all cyclists), but that should actually be a net benefit.

If public transit is growing, more people will be able to not-need bikes.

> To comprehend the difference in scale, view images here [1].

Or you, view images here: https://newworldeconomics.com/what-a-real-train-system-looks... and comparisons here https://newworldeconomics.com/the-problem-with-bicycles/

e.g. [1] "The typical U.S. solution is to surround the train station with acres and acres of free parking.[...] There are 157 acres of land in this photo. When you step off the train, you have immediate walking access to 157 acres of /nothing/"

and [2] "The better solution is to surround the station with all the highest-value property. All the best offices, stores and restaurants are as close to the train station as possible, so we can walk there from the station, and where there is the most pedestrian traffic. Plus, you also try to put as many apartment buildings there as you can, so you can easily walk to the station in less than ten minutes."

"if you want people to be able to live without automobiles, you have to make it easy to get from the train station to wherever you want to go on foot. This means you put all the good stuff right up against the train station — even build it into the train station itself if possible. When you step out of the train station, you want to land right in a wonderful pedestrian Traditional City environment, not a parking lot wasteland."

When you switch a "large" surround of car parking for a "large" surround of bike parking, that doesn't fix anything. I put "large" in quotes because the measure is not abstract meters, dollars, or kilos of concrete, the measure is human size and human footsteps - walking past 12,000 bikes is 90% of people walking further for no benefit, while the bike owners also walk further for a small benefit of part of a journey, and puts desirable city space to use by metal instead of humans.

To be clear, I don't want to displace public transit -> bicycles. I was talking about cars -> bicycles. Densest cities are best served on foot - the places nobody would dare convert to car transit.

As I emphasized, cars -> bikes is not 100 -> 60, but 100 -> 10. Meaning not 1.5x nor 2.5x but 10x density. A moderately priced double-decker staggered height bicycle parking comfortably fits 20+ bikes in the place of a single car.

The only places that require comparatively large bicycle parking areas are large transport hubs, and in the example, the added distance for pedestrians is less than going between platforms, if any at all.

In a typical not-overly-dense places, bike travel is technically faster than foot if you're going more than about 50m + about 120% of distance to parking (if not along the way).

> U.S. solution .. 157 acres of free parking

That is truly foolish, and would fit over a million bicycles even without racks.

[jodrellblank]

> The only places that require comparatively large bicycle parking areas are large transport hubs, and in the example, the added distance for pedestrians is less than going between platforms, if any at all.

Everything requires comparatively large bicycle parking areas. Here https://newworldeconomics.com/wp-content/uploads/2017/01/osa... is perhaps 5-10% of the visitors bike parking, making the street 30-40% blocked and 30-40% wider for everyone.

Here https://newworldeconomics.com/wp-content/uploads/2017/01/gak... are maybe 10-20 bikes clogging up the path for thousands of people.

> I was talking about cars -> bicycles. Densest cities are best served on foot

Right, so if you're redesigning smaller and denser, why on earth would you build so everyone needs bikes, instead of building so everyone doesn't?

And if you're not redesigning smaller, and distances are still car-suburb distances, they're still too far for bikes for most people and most journeys. You might have to do a 20 mile round trip to get into Houston center and back, for example, that's 1.5-2hrs biking. Way outside what you could expect most people to want to do regularly compared to say a 15 minute walk.

45k people live in https://newworldeconomics.com/wp-content/uploads/2017/01/gak... this photo with a ~10 minute walk to all of those places including a train station with lots of regular large trains.

> The only places that require comparatively large bicycle parking areas

All bicycle parking areas are comparatively large for the people who don't have bikes. "The space of a single car" is ~3 meters. You only need 30 of those to push your walking commute, trip to the shops, visit to your friends, out by +1km and +2km after a round trip. Building for the 10% of bikers compared to the 90% of non-bikers is insanity.

> That is truly foolish, and would fit over a million bicycles even without racks.

If it did, it would still be 157 acres of non-place nobody wants to go to, spend time in, and resent having to get to the other side of. The foolishness is having that much inhuman space dedicated to metal storage, not that it's dedicated to fossil fuelled vehicles instead of pedal powered vehicles.

[jodrellblank]

That is, the desire for and apparent need for bicycles comes from having a city built large enough for cars, too large to walk, and then having the cars removed. Where you are miles from your destination and between you and your destination are acres of no-place, nothing nice to travel through, nothing interesting to do.

In a city built small enough to walk, bicycles are unwanted and unneeded extra hassle, and when you occasionally do have to walk a couple of extra miles it's through a vibrant, busy, maybe even beautiful, human space not concrete void.

"It should be obvious that it is better to not need a bike than to need one. [...] we should not think about bikes-instead-of-cars, but rather getting over this unhealthy fixation on My Personal Transportation Device"

[InitialLastName]

Don't fight it so hard. Every person on a bike reduces traffic on your car commute.

Plus, they don't dump any particulates into your childrens' lungs.

[jodrellblank]

"Accept a bad solution because otherwise I'll threaten your children with a worse one" might be a convincing argument, but it's not a good argument.

Designing things around bikes, and then everyone needs a bike, is a worse option than designing everything around humans (instead of some kind of vehicle).

[dahart]

Neither of those sentences is living in reality. Nobody's threatening children with a worse solution, we already have the worse solution, our children are already inhaling the pollution. You can choose to keep it or choose to lessen the pollution. As far as pollution goes, there's little difference between bikes and whatever alternative you're proposing (walking?). Walking doesn't pollute, bikes don't pollute, cars do pollute heavily. Bikes aren't a bad solution to pollution, they are a perfectly good solution. One of many.

> Designing things around bikes, and then everyone needs a bike, is a worse option than designing everything around humans (instead of some kind of vehicle).

I'd fully agree we should design things around humans, but where are people designing cities primarily around bikes? And what, exactly, are the problems we actually have with bikes? Not the fear-mongering made-up FUD, but real problems that exist already. Bike parking space is not an actual problem today. What is?

What does it mean - exactly - to design around humans? You could argue the problems we have are because we designed around human convenience already, and allowed our walking space to be paved and prioritized for cars.

Your arguments are vassellating between comparing to cars and then not comparing to cars. What's the goal post here? Are you demanding something perfect, or do you want to improve considerably over the crappy position we're in with cars? Is removing all vehicles entirely a realistic goal? Is redesigning all the largest cities on earth, and getting everyone to work within a mile of where they live realistic? Why are you trying so hard to lump non-motorized vehicles together with motorized vehicles? There is a large difference between having a gas-consuming engine and not having one, don't you agree?

[jodrellblank]

> bikes don't pollute,

The making of bikes, and the concrete for them to ride on, involves pollution and externalised costs. Bike tyre dust pollutes, abandoned rusting decomposing bikes pollute. Less than cars, no question. "they don't" - not true.

> And what, exactly, are the problems we actually have with bikes? Not the fear-mongering made-up FUD, but real problems that exist already.

They aren't good enough to replace cars. They aren't a good improvement over not needing to own transport. They aren't a good improvement over walking in most dimensions, and the ones they are are dimensions that would be better eliminated than papered over with bikes.

> What does it mean - exactly - to design around humans?

Design around what the human body can do (mostly) unaided. Glasses bring your eyesight back up to human norms, we don't design imformational screens so everyone needs magnifying lenses to be able to read them. Hearing aids bring your hearing back to human norms, we don't make important announcements quietly enough that everyone needs a hearing aid to be able to partake in society. Walking sticks aid balance for the disabled, we don't make waterbed rolling walkways so everyone needs an extra third point of stability to avoid falling over. If it's too far to comfortably walk every day, it's too far. If that can't be helped, mass transit. Personal transport should be a thing people don't need, but the 2% of people who ride bikes today can be the 2% who ride bikes tomorrow if they want.

> Is removing all vehicles entirely a realistic goal? Is redesigning all the largest cities on earth, and getting everyone to work within a mile of where they live realistic?

Is preventing catastrophic global climate change realistic? Is ignoring mass transit so you can strawman that everone needs to work within a mile of their home instead of everyone having work or train station within a mile of their home, reasonable?

> Why are you trying so hard to lump non-motorized vehicles together with motorized vehicles?

Because that's where they belong. The only way bikes are going to become as popular as they need to be to satisfy the pro-bike agenda is when they become motorized. They will approach "electric cars" closer and closer.

> where are people designing cities primarily around bikes?

Good question. If bikes are so great and the answer to pollution and the future, where are people designing cities primarily around bikes? Nowhere? It's old places designed around walking, and new places designed around driving, and occasional neighbourhoods redesigned around walking. Bikes are incidental in both approaches, like nobody is redesigning cities around skateboards, unicycles, Segways, hoverboards, Kangaroo boots, rollerskates, rollerblades, monowheels, pogo sticks, velocipedes, stilts, or spacewalkers. Bikes belong in the category of those things. Fine where they are, not a thing to promote for daily commuting and mass transit of world populations.
