At airports, I'd walk way faster than normal on those things. It was an interesting sensation and while a little more dangerous (I've never once had an accident, collision or otherwise), walking faster would kind of "shoot" you off at the end of the walkway.

[@blarghmcblarghson1903]

Hong Kong has tons of moving walkways all over the city, just from my casual observation (literally hundreds of people daily for the past 14 years I've been living here) the study that Simon references isn't wrong, a vast majority of people on moving walkways don't use it to speed up, but just as a convenience to take short breaks from walking. Edit: and to clarify, people don't just slow down, they tend to stop completely. Standard etiquette in Hong Kong is if you want to stand you stick to the right, let the brisk walkers overtake on the left.

[@annabethwivell327]

I’ve used moving walkways a lot in airports, and to me their advantage is not that they are faster (though they can be if you walk on them at a decent pace) but that they reduce fatigue when you have to walk for half an hour to your next gate while dragging luggage and feeling jet lagged. Which is probably why they do still exist in airports. And I don’t see how they would be any more dangerous than an escalator in a shopping center.

[@JesusKreist]

#1 "Moving Walkways" are a lot longer than escalators and mostly fenced in at the sides for security purposes. Meaning if you had some kind of emergency it wouldn't be until the end until you effectively could be helped. #2 On "moving Walkways" you have a lot more diverse speeds of the users than on escalators. Meaning the chance to bump into someone or bumped from behind is far greater. #3 If "moving Walkways" fail it is likely a far greater cost than repairing an escalator with the same problem due to the length. These are but a few of the disadvantages that "moving Walkways" have above simple escalators.

[@annabethwivell327]

As a moderately disabled person, I LOVE moving walkways in airports, especially when I'm expected to get to the next gate in under 15 minutes yet it's a mile walk, and they wont provide me with alternative transport. That said, people need to WALK on them for them to work. I unapologetically demand people move to the side if they are standing and blocking the entire walkway.

[@joylox]

I've seen some airports with a line down the middle of theirs, for a fast lane and a slow lane. Which is great as I have a disability where I get dizzy and fatigued more often, so I sometimes need to lean against something or sit on my suitcase for a moment.

[@genkibob]

Yeah, usually a loud "Coming through!" is enough to get them to stand on one side or the other. The smarter run airports have feet painted on the walkway to indicate the walking side vs the just riding side.

I never quite understood the monorail's failure. I used to live in L.A. and often thought a monorail track that paralleled the 405, the 10, and a few other key freeways would be a pretty good way to move people around without the pesky tunneling of a subway, and nice views. (A monorail from Cheyenne Wyoming to Colorado Springs, hitting Fort Collins, Loveland, Denver, and Castlerock would be quite nice too) It might be impossible now, but when they were building the freeways in the 40s through 60s the monorail concept was, at least on paper, pretty popular (they made on in Seattle for example). I'm surprised they never made any in L.A. for general use. Or if they did, they didn't last very long.

Various light urban rail systems on elevated tracks are running around cities and airports around the world, and often doing just fine.

I work in the New York City area, and the most common emerging transport I encounter is the electric scooter (the kind with 2 small wheels front and rear, a handlebar, and a short platform between the wheels for one's feet). They seem to strike a good balance between being portable, and still giving someone speedy mobility on paved routes. They have their issues, but people deal with them and use them for modest trips in the city. I was able to try a Segway a few years ago, it was a loaner to our organization to test it for possible use. After a few minutes to become familiar with it, it was obviously a remarkable machine. It seemed to respond almost intuitively to one's desire to go in any direction, and was smooth, silent, and quick enough to get one into trouble on a sidewalk or hallway. Very impressive... but, too heavy for me to take down a flight of stairs to the subway on my way home. It was great for short local trips but would not be practical to zip me 6 miles away back to Brooklyn (unless there had been some dedicated paths for it, which sadly don't exist). I guess the weight and cost of the Segway worked against their wider adoption, so today I see many commuters with $500 25 pound scooters carry their scoot, wheel it off the subway or bus, fold the handle bars up, and zip off on their way.

[@Henchman_Holding_Wrench]

I thought it was pretty cool to see such a diverse population on electric scooters. Office workers, construction guys, nurses, students. It was neat. But, of course, it slowly escalates. Now the streets are flooded with those e-bikes and unlicensed motorcycles going faster than cars, weaving, and running red lights.

Pretty common in china are the segways without the handles. Can fit on ebike and take it into community that doesn’t allow delivery ebikes. Or to school. Ebikes are more common .

[@alanlight7740]

In 1995 I was briefly in the Birmingham, Alabama area where in one of the suburbs I saw a young man scooting around on his own homemade motorized skateboard. I thought at the time that has got to be about the most energy efficient transportation possible: just a small engine, small fuel tank, four small wheels, and a platform to stand on. The chief problem with it was the fact that although skilled skateboarders could steer it where they wanted there are an awful lot of potential riders who wouldn't even be able to keep their balance on it - to say nothing of braking or adjusting speed. As you say, the electric scooter strikes a balance: a folding handle makes it easily portable _and_ (perhaps more importantly) easily stowable. One problem in a city with bicycles and Segways is finding a secure place to store them when they're not in use, but an office worker can stow an electric scooter with a folding handle under their desk, and going about town they can even sling it over a shoulder if they need to briefly go into a shop. Of course the handle provides controls for speed and direction, but more importantly provides just enough connection to the platform to make it comfortable for most riders to maintain their balance. Modern batteries with electric motors of course reduce maintenance issues to almost zero. The simplicity and small size keep the costs quite reasonable, whether it is used in addition to or instead of a car. The range isn't great, but it's about solving the last mile problem (or even the last five miles problem) for people who wouldn't otherwise be able to use public transportation - or even if they just don't want to try to find parking in a congested area. That said, the Segway has some great technology in it and those innovations will very possibly be in widespread use elsewhere in the future - but it did not fit the way that humans actually live, and that was where it failed as a product.

[@roverdover4449]

yeah, it's kind of funny, if the segway inventor had just put the wheels one in front of the other, instead of side by side, he could have actually changed the world. Instead we had to wait another 20 years. I guess smaller batteries were also required too.

Whilst Segway undeniably was a huge fail, mostly by being too expensive and bulky, I have to give credit for it's makers - it's a pretty cool piece of kit, but especially their vision was very correct.

If Segway would have had the idea to just rent them rather than sell, things could have been very different.

Segway was a very predictable failure. I was living in League City, Texas and attending the University of Houston - Clear Lake at the time the Segway was introduced.

But then I recalled how easily we could get around Houston in the days after Tropical Storm Allison. It's one thing when the temperature's hot enough to melt Inconel X, but riding a Segway around the Houston area when you're having 28 inches of rain dropping down on your head in thunderstorms simply isn't a good idea. Worse yet, the Houston area isn't well suited for riding something like a Segway: things are far too widely spread out, and the battery life's too short.

I don’t slow down at all when on there and I’ll yell out “LEFT” like when I’m on a bike and passing someone if someone is moving too slowly, or Lord forbid, standing still on the moving sidewalk.

[@jgdooley2003]

Good man David. The people in Dublin Ireland actually STOP on the moving walkways not realising that their intended purpose is to speed up transit to remote gates in airports and other transit hubs. They do the same on escalators stopping often 2 abreast and blocking anyone who realises that you walk up or down an escalator and also that you keep moving off the escalator when you reach the end, not stopping like a headless chicken to have a gawk around blocking all the people behind you. This is the whole purpose of such devices, to speed up movement in spatially restricted areas in airports, hotels, shopping centres etc. Their benefit is derived when people walk on them. I'd love to see these people try the stopping stunt on Londons underground at rush hour......

[@zafarsyed6437]

Yeah... you're running late cause you're running late! Have a non-common name or anything beyond beige-colored skin, and you would really know what "unnecessarily thorough" means! Also, having worked for DHS, I've learned that it's not the local persons making the policies but some agency subcommittee or remnant of something that some security company recommended back in 2002-2006. At least for the past 9 years, everything allowed and not allowed is listed on the airlines' websites, and even how you should pack or unpack for screening is on TSA website. Nowadays (after I've left DHS) I get to the airport 1 hour before my domestic flights at any of the major airports and breeze by. Just have to observe which and how to get to the lines that move, unpack, get through with pockets empty, repack quickly and out of the way of other people, and like you, actually walk through the airport. So many passengers wake up less than 3 hours before their flight so they drag their sorry asses through the lines and move even slower through the airport.

I was going to say I'm that rare guy that uses the moving stairs and walkways as they were designed. And you all beat me to it, that's fun. So are the speeds you can achieve! Always a little sad when it's not used right. I've flown enough to see both crowds and the line on the right on the devices. And I don't mind excusing myself past the humans on display. And I like to even thank the people that make the effort when they see someone that needs to be somewhere. I wonder what it's like to have someone blow past you as you do that weird slouch but I appreciate the space.

Thankfully, the Japanese will apologize for their inconvenience, whereas TSA will simply feel good about themselves in some hollow, self-supporting way. Just last month, I watched a Seattle TSA agent move my bags to a different line where it could be “randomly” chosen to perform a chemical test. Of course, as always, it was negative. Meanwhile, my spouse often has experienced the dreaded SSSS. This is all despite our Global Entry and Clear statuses.

[@joegrey9807]

A lot of these 'world changing' forms of transport come into the category of 'a solution looking for a problem'. Or at least, a solution that resolves one relatively minor problem in another form of transport, but creates far more other problems. Monorails, hyperloops, maglevs and other gadgetbahns come into that category. There may be isolated cases where they're the most practical option, but not enough for mass implementation, and certainly not enough to counter network benefits of established systems.

[@toddfraser3353]

However a lot of the successful world changing inventions, were also criticized for the same argument. As every new technology has a tradeoff over the previous, which there will be often a group of people unhappy to give up. If you were drunk the horse will often bring you back home, as well the horse can traverse more tarrains. However the automobile being faster, less maintenance, and environmental friendly (with early 20th century standard) made it become popular once it became affordable for most people. However, history could have gone in a different direction if some circumstances were different. Say no termerence movement, and there was higher drunkiness.

The hyperloop (or some other vacuum-tunnelling vehicle) is probably still going to work and be successful, at least in major transportation corridors. But I won't live long enough to see this prediction provided right or wrong. Travelling in a vacuum means you can easily travel Mach 25+ without nasty side effects like air friction. I see no reason why you couldn't get from one side of the earth to the opposite side in less time than it would take you to fall through a tunnel carved into the earth. However for this to work you would have to be flipped upside down in the tunnel because you would have to be travelling in the tube faster than satellites cross the sky (about 18,000 MPH.) If you were travelling faster than that across the surface of the earth you would have to be rotated upside-down because your acceleration would be pointing up rather than down.

Moving walkways were not meant to get you there faster, it was meant to take the strain off walking, especially long distances. They move at a walking pace because the speed is roughly something we can comfortably step onto and maintain stability, like an escalator. Especially while hauling something like luggage. You also forgot hover vehicles. They were hyped hard only for their skirts to be detrimentally easy to damage on ground and rather unstable making hard turns.

The "Domain Express Footway" running from The Domain to Hyde Park in Sydney was opened in 1961 and still operates to this day. At 207 metres long, it is the 3rd longest in the world. I absolutely loved the moving walkway as a kid in the 80s and was disappointed when my father told me any plans to expand their use across the city had long since been abandoned.

[@artistjoh]

The world's longest moving walkway is here in Sydney connecting the Domain Parking station to Hyde Park. The many times it stops for repairs and maintenance highlights why these things are impractical, however, when it is working it is great. Unlike the commentary here, people tend to walk on the walkway, and walk at normal speeds. It is fast enough to experience wind through the hair. It is much faster than normal walking. I am happy that this 400 meter slice of the 1960's still survives. I would also challenge the notion that airport travelators are a useless idea. At airports people are carrying luggage, and travelators, especially for older people, can be a welcome way to rest for a short while still moving forward. Thus, the observation that these people walk slower, or just stand on the travelator is part of their advantage at airports, and not the negative that Simon mentions.

[@jlust6660]

I think there are very few airports that are so hard to navigate that these travelators are actually necessary. Most people can just drive their trolleys over the endlessly flat floors and people really struggeling to get around can usually get better assistance anyway. This is not the first time I have heard that these travelators offer more psychological advantages than actually saving time. That doesn't mean that I think that they are entirely useless or at least not fun, but if you looked at them economically I wouldn't be surprised if the advantages don't justify the effort.

As someone with fairly severe mobility issues, I wish there were more options like moving sidewalks, Segway-style devices, or even PeopleMovers like the WEDWay PeopleMover at Walt Disney World. I’m capable of walking short distances but I can’t walk more than about a block or two without ending up in debilitating pain, so my only real options most of the time are cars or wheelchairs. I HATE being in a wheelchair; it’s a psychological thing but I feel like being in a wheelchair means I’m a total invalid. I prefer to walk when I can, and I mainly need alternative forms of transportation to get from place to place, like from one store to another in a large shopping district. Moving sidewalks would allow me to be more mobile and go more places, as would other forms of transportation that you can step onto or off of wherever you’d like. I actually love going through airports that have moving sidewalks or trains/monorails. Intercontinental Airport Houston even has a WEDWay - the only one ever sold by Walt Disney Imagineering to an outside purchaser - and it’s fantastic! As it is, I’m just stuck at home most of the time because it’s simply too difficult to lug a wheelchair around when I only need it for certain situations.

I can't for the life of me reconcile that with the Segway. So I always thought IT was something different than what was presented. If IT truly was as impactful as implied, it might have been hit with ISA secrecy order (there are around 6.000 of those active right now) somewhere along the development, and the Segway was the hastely substituted in. That would also account for both the never explained delay and the ridiculous levels of secrecy that surrounded the development. But I don't know...I just can't se how anyone, let alone but a passionated inventor could be so hyped about the Segway.

That's all well and good, except when we were going down a hill, gravity caused me to exceed that speed, and I had to hold on for dear life to resist being dumped onto the asphalt at a fairly high speed by the automatic pull back.

Segway's issue was more with the price point than the tech... it wasn't a terrible idea for a scooter to get around places that don't use cars as much, but the problem was who is going to pay $5,000 for something when they could just buy a bike for a few hundred dollars or less?

I didn't think the segways were any better than most of the cheap stuff that is out there now to ride around on.

[@alanlight7740]

It's also form factor. Once you get somewhere, where are you going to park your Segway? Can you easily take it on public transport with you? How do you get it up or down stairs? An electric scooter with a folding handlebar you can fold and carry with you on public transport or up and down stairs, and you can stow it under a desk or in a locker. If you want to park on the outskirts of town where parking is cheaper and easier to find you can throw one or several scooters in the trunk and use it only for scooting around the city center. It's a last mile solution - and in fact, even an unpowered scooter isn't too bad for short distances.

Similarly, the tunnel underneath Waterloo station connecting Jubilee line to the other ones is so long that there is a pair of travelators installed to aid commuters. And when you are in a hurry, you *fly* through that tunnel. Frankly, I wish there was more of those around in underground stations around the world.

I remember the moving walkway expanded into a highway system in Isaac Asimov's novels, replacing cars as the main mode of transportation. Isn't that an intriguing idea? Unfortunately for the concept, metros and trains are just much more efficient, comfortable and safe at doing just that. And they can be nearly as convenient if the trains are fast enough and frequent. High speed rail can probably be even better. Then trams and bused are safer and convenient for shorter trips at moderate speeds. Finally, bicycles, while taking more space than a pedestrian, are usually small enough that they can easily be used for the last mile or two. And they can move cargo. The last problem is reliability. If your transport system breaks down every few weeks, if not more often, without another way to get to their destination, in a reasonable amount of time and at a reasonable peice, then your citizens will be quite unimpressed and will stop using it entirely.

[@OgdenM]

One could argue that Segway was revolutionary. It was the first battery powered individual transportation device.

I've also been in one. Yah, super cool. I didn't know about the maintenance needed each time you take it in the water.. but it makes sense. Also, one thing the marketing never talked about: How smelly they get with mold and mildew. The things have leather seats and carpet in them! Even if the cab doesn't leak, you're going to get a decent amount of water inside the cab from getting in and out of it. On top of that, water ends up in places on the outside of the car where you just can't get it dry.. and mildew happens fast. The one I was in was in GOOD shape but ugh, the smell. Speaking of smell, the exhaust was HORRIBLE. I get why they didn't pass DEQ.

Herbert Garrison, a teacher from Colorado, invented the "IT" back in 2001. I was a larger electric monowheel that you rode inside of. Super cool idea.

[@SolarizeYourLife]

Out of the Segway came the Segway mini and Electric unicycle... Both are more useful than the original... Sadly Dean Kamen did not expand into the other two products...

[@alanzyoutube]

I remember when the Segway was announced and the company said it would change the world.

And then the creator/owner of Segway committed suicide, by driving a Segway off a cliff.

[@SEAZNDragon]

The Segway was definitely oversold. If the inventor just came out with "Hey you got a large compound where is a pain but car/bike traffic is a no go? Then try my motorized platform the Segway. Yes it looks funny but your feet will thank you" then I think a lot more people would be open to it. Giving a device a code should only use for things like, I don't know, a nuclear bomb maybe.

Can add Musks Hyperloop to this list, or virtually any of his proposals for that matter. Promised a ride that outstrips rail and busses for a dollar a ride, and he delivered... non self-driving taxis going 15-30mph in a extremely tight one lane, one mile long tunnel that costs $55m to build and $10-15 to use. A little bit short of the 800mph $1 ride he claimed he could deliver. The worlds largest conman and he still has so many people fooled, it boggles the mind, Theranos on steroids.

[@tidepoolclipper8657]

Too early to actually give the hyperloop a verdict. As for his other proposals; Red Dragon and Lunar Dragon do not count as being part of those failed proposals; with Lunar and Mars Starship still being on jury (and if you want to talk about delays; SLS has really been suffering in that department). Red Dragon was scrapped because they were unable to get permission from NASA for jet powered landing with the Dragon 2 and not to mention Starship is larger anyways; meaning they weren't gong to ahead with Red Dragon in the end anyways. As for Lunar Dragon 2; they very well could convert one of the remaining Dragon 2 capsules if they wanted, but Lunar Starship makes that idea pointless now. Is Elon perfect? No; his business practices could use some work. However, many other billionaires who own a business are worse than Elon is in that department (I'm looking at you, Jeff Bezos) and at least he's willing to take risks in regards to technology; even if he is overly optimistic with his deadlines (something even Elon supporters often admit to) and has his moments of failure (heck, SpaceX almost died with Falcon 1).

@@tidepoolclipper8657 hyperloop is a 100 year old concept and all the transports in the video have more real world applications than the hyperloop will ever have. Working with vacuums is just too hard and impractical to be a reliable method of mass transit. The boring company, the electric semis, robo taxis etc... are just cons for gullible people.

[@tidepoolclipper8657]

@@louislux Yes, we know the concept was not invented in the 21st century. If anything, Elons claim he came up with the name; not the technology itself. Either way, it's still worth it to dust up the old 20th century vacuum tube train plans and try to improve upon them; even if the technology won't see full implementation until centuries down the line. Maglevs in their own right still have the issue of air resistance. At the least, valuable data can be gotten from this and be applied to future projects that don't necessarily involve Elon.

[@jamesengland7461]

You don't even have the two separate ideas correct. Hyperloop is not the same as the Boring tunnel with cars driving through it. Further, the tunnel cars are easily automated, but that's not yet legally permitted.

[@alanlight7740]

LOL - you've confused so many things in your statement that it's difficult to untangle them. Loop and HyperLoop are different things. That's why they have different names. There are two tunnels at the LVCC Loop, one going each way, and if you parked a car in the middle of one of those tunnels there is plenty of room to get out on _both_ sides. The lane is about the same width as a regular highway lane. You didn't really expect that the whole system would be built out overnight without any need for development and testing, did you? Because that would be insane.

[@dustieboots546]

This is a great video! You could also make a video about the opposite. The modes of transportation that actually changed the world.

Here in Australia, we have motorised scooters everywhere on the street to hire. They’re constantly in use, I wonder for how long.

We have Moving Walkways in Paris, France, in some Metro Stations. It`s fun to use them.

[@shrimpflea]

They are used at most major airports. Useful except for people that just stand on them.

[@anyawillowfan]

As someone who struggles with walking, moving pavements do appeal to me (though I also can't stand long), but honestly I'd take accessible and safe pavements, roads, and entrances/exits if given a choice. Of course, that offers government no benefit so generally where monetary spending is needed, it comes very far down the list of 'necessity', whereas nuclear weapons rate priority (in the UK at least).

[@MattBellzminion]

Certainly not a major invention, let alone an infrastructure project, but I've always had a fascination with shoes that double as skates, thanks to pop-out mini-wheels which the wearer can deploy with the press of a button or similar conversion mechanism. There have been two brief vogues for these admittedly tricky and problematic products in my lifetime: in the first, my mother denied them to us kids over safety concerns and probably also their cost; and the second time around, I was too old, too fat, too self-conscious, and, most damningly, solely responsible for my own health insurance and medical expenses. As it turned out, these combination shoe/skates were fairly dangerous, as a number of younger folks got hurt (some of them seriously), and the product was recalled and banned by the US govt. -- at least in this second time around. (I was too young to remember much about how the first such product fared.) To add insult to injury... literally... this especially adventurous footwear category had a reputation of being rather disappointing when worn simply as shoes, too. Maybe some daring enterprise will make a new & improved version at some point... the third time's the charm, after all. But until that happens, we'll always have "L.A. Story", in which Steve Martin's goofy TV weatherman character pops his wheels to go skating in NYC's Guggenheim Museum.

Heelys still exist. They're great. Just got a new pair this year after using my old ones for 10 years or so.

[@telotawa]

moving walkways at airports are very useful for me because i always rush to my destination as fast as possible, honestly i wish there were more of them in certain airports (Schiphol has a stupidly long distance you have to walk to get from the gates to the baggage claim and exit, it's probably 10 minutes of walking)

[@xWink]

Simon should check out electric unicycles, which are starting to become very popular in North America. The legacy of the Monowheel has plenty of potential thanks to self-balancing technology.
