'Uber Was Supposed to Help Traffic. It Didn't. Robotaxis Will Be Even Worse.' (sfchronicle.com) 264

Saturday the San Francisco Chronicle published a joint opinion piece from MIT professor Carlo Ratti (who directs an MIT digital lab exploring the collection of digital data about urban life) and John Rossant (founder of the collaborative data-sharing platform CoMotion).

Together they penned a warning about a future filled with robotaxis. "Their convenience could seduce us into vastly overusing our cars. The result? An artificial-intelligence-powered nightmare of traffic, technically perfect but awful for our cities." Why do we believe this? Because it has already come to pass with ride-sharing. In the 2010s, the Senseable City Lab at the Massachusetts Institute of Technology, where one of us serves as the director, was at the forefront of using Big Data to study how ride-hailing and ride-sharing could make our streets cleaner and more efficient. The findings appeared to be astonishing: With minimal delays to passengers, we could match riders and reduce the size of New York City taxi fleets by 40%. More people could get around in fewer cars for less money. We could reduce car ownership, and free up curbs and parking lots for new uses. This utopian vision was not only compelling but within reach.

After publishing our results, we started the first collaboration between MIT and Uber to research a then-new product: Uber Pool (now rebranded UberX Share), a service that allows riders to share cars when heading to similar destinations for a lower cost. Alas, there is no such thing as a free lunch. Our research was technically right, but we had not taken into account changes in human behavior. Cars are more convenient and comfortable than walking, buses and subways — and that is why they are so popular. Make them even cheaper through ride-sharing and people are coaxed away from those other forms of transit. This dynamic became clear in the data a few years later: On average, ride-hailing trips generated far more traffic and 69% more carbon dioxide than the trips they displaced. We were proud of our contribution to ride-sharing but dismayed to see the results of a 2018 study that found that Uber Pool was so cheap it increased overall city travel: For every mile of personal driving it removed, it added 2.6 miles of people who otherwise would have taken another mode of transportation.

As robotaxis are on the cusp of proliferating across the world, we are about to repeat the same mistake, but at a far greater scale... [W]e cannot let a shiny new piece of technology drive us into an epic traffic jam of our own making. The best way to make urban mobility accessible, efficient and green is not about new technologies — neither self-driving cars nor electric ones — but old ones. Buses, subways, bikes and our own two feet are cleaner, cheaper and more efficient than anything Silicon Valley has dreamt up... Autonomous technology could, for example, allow cities to offer more buses, shuttles and other forms of public transit around the clock. That's because the availability of on-demand AVs could assure "last-mile" connections between homes and transit stops. It could also be a godsend for older people and those with disabilities. However, any scale-up of AVs should be counterbalanced with investments in mass transit and improvements in walkability.

Above all, we must put in place smart regulatory and tax regimes that allow all sustainable mobility modes — including autonomous services — to scale safely and intelligently. They should include, for example, congestion fees to discourage overuse of individual vehicles.

        No, they aren't. Uber is a taxi service. Bob wasn't already going to 100 Main Street. Someone contacted him to pick them up and take them there. This means more vehicles coming in from outside the area to deliver people to their requested destination.

          This is the crux of the problem.

          The idea is that if everyone didn't own their own car, the streets would be less crowded.

          But in reality, the number of trips by car remained the same, except now the car wasn't starting where the person making that trip was (e.g. in a parking spot), so a car needs to be brought to the desired starting point. You have actually increased the number of trips by car, even if you have potentially reduced the total number of vehicles... any real reduction in number of owned vehicles just means more parking, not less traffic.

          The only ways to reduce traffic (short of an outright ban on personal vehicles) are either to make walking a more viable and attractive option, and/or to provide better mass transit that reduces the number of vehicles by transporting more people at once.

              The actual manufacturing of the vehicles themselves is still a significant source of pollution.

              There are any number of studies (here is but one example [sciencedirect.com], here's another [iea.org]) showing that the emissions associated with building a vehicle are quite small compared to those of actually using the vehicle. EVs have higher up-front pollution associated with them, but drastically lower operating pollution.

              If you are concerned about pollution from vehicles, the place to look is how far and often they are driven, and less about their manufacture.

            Pretty much. However, I'd argue that robotaxis could help with this. Or even just self driving cars.

            But at least initially, they might even make the problem worse because of said multiplication effect(taxis make 1 trip into 2 - first the taxi has to reach you, then it has to go to your destination, then possibly even reset to a holding area again, making it 3 trips). This is all about shifting the margins, by the way. Some people already live without cars, some aren't going to get rid of their car ever.

            • Simple solution: Make downtown parking expensive & public transport cheaper, quicker, & more convenient. Where I lived last year, bus/tram fare was €0,35 per trip including transfers (with a convenient contactless card). They run all routes every 10 minutes. There's almost no parking at all downtown. Pretty much everyone walks, cycles, e-scooters, or takes the bus/tram. Where I am now is similar but the fare is a whopping €0,70 per trip. It's outrageous! ;P

              The problem, in my mind, all comes down to density. You want walkable neighborhoods where people have a realistic chance of getting to the services they want and need by walking there on a significant percentage basis? You need density.

              To an extent but not as much as most people think. Oulu in Finland has about the same size and density as London, Ontario, the latter of which is a pretty typical sprawly North American town. Oulu also gets cold and with heavy snowfall every year, and yet people bike throughout the year. Half of the kids go to school by

              The answer "how" is related similar to how you get people to take public transport: make it not suck. If every road was an uncleared dirt track next to a ravine, and frequently crossed by unlabelled freight train tracks almost no one would go by car. People bike because the experience is good: there are good quality bike routes, which are treated with the same degree of respect as cars: safe routes are provided, bike paths are cleared or compacted (snow), and etc. So, cycling doesn't suck.

              You can make public transport not suck too: if public transport is stuck in the same traffic as cars, then going by bus or tram if you have one is basically like a bad version of driving.

              And yep, on the small scale it needs to be reasonable. The laws that require massive parking lots for every strip mall store not only encourage driving, they also discourage anything else because it's pretty much worth (and in some cases necessary) to drive between shops in the same strip mall rather than walk.

              In America as it is today the average journey is less than 3 miles. That's maybe 15 minutes on a bike, for a casual cyclist on an upright city bike or 10 on an ebike (or less for a keen cyclist). Even for relatively slow stop/start buses that journey is a question of minutes.

              For America it's not even that things are too sprawly (they are not), it's that everything has been designed exclusively around cars so everything else sucks even if the distances are not too bad. Another example would be peachtree, GA. Not nearly so car dependent as most places, but they went a novel route providing lots of gold cart tracks, making the city very accessible. The point of that is that despite being a somewhat normal-sprawl level of place, it's very accessible to low speed (max 20mph) levels of transport, and so well within the reach of bikes and ebikes too.

                I mean, a typical weekend for me, I want to BBQ on the smoker.

                I'll run to Costco and get a vac-pak whole brisket...about 12-15lbs. Let's say I get some other things...case of cokes and/or water, maybe a case of beer, etc if having friends over and watching football and let's just say, it's a small Costco trip with pretty much just that and not a lot of other stuff, which I often do stock up on.

                And yes, I hit Costco at least bi-weekly.

                Now...how do you propose I get this home on a bicycle?

                How would I get this home on public transport like a bus?

                I'd have to somehow haul all this on a bus, hope I had open seats to put it....and that doesn't cover how the heck I'd get all my stuff from store to bus stop and then bus stop to home.

                This is just one scenario....Weekly, I generally look over the grocery specials at the stores in my area. I pick out what's the best items on sale at each store and I generally run to 2-3 stores to pick up what's on sale. I do this in one trip...so that I have things to cook and eat on all week.

                I rarely eat out, I cook mostly at home.

                I have a bicycle, a nice one...I ride it for exercise and entertainment, but, lol....it isn't a practical mode of actual travel and transport for my normal every day life....not the MANY people in my neighborhood or typical US neighborhoods across the country.

            The only ways to reduce traffic (short of an outright ban on personal vehicles) are either to make walking a more viable and attractive option, and/or to provide better mass transit that reduces the number of vehicles by transporting more people at once.

            Not necessarily the only way. In some cases, human behaviors when driving can be demonstrated to be one of the causes of traffic congestion in the first place. In a scenario where all the cars on the road are self driving and every car has its position, speed, etc. negotiated with all of the other cars on the road there is the potential for traffic jams to be greatly reduced. Consider, for example a two lane road in the city where a truck stops in the right lane and the traffic backs up behind it, with everyone trying to change lanes into the left lane to get around it. A traffic system like I described would not stop that from being a bottleneck, but fully coordinated driving between all the vehicles involved could allow the bottleneck to be cleared a lot faster. With such a system, you could eliminate traffic lights. Potentially, cars would not even need to stop at intersections, they would just drive by each other with sufficient tolerances to avoid collisions. Lanes would not even need to be one way any more. You could have two lanes and each direction dynamically turn into three lanes in one direction and one in the other as traffic demands. Obviously though, in a situation like that the rules of the road would be too complex and hard to follow for human drivers, and any human drivers on the road would mess up traffic horribly. so this would be an all or nothing sort of thing. Also, not understanding the rules of the road as your self-driving vehicle whizzes past other cars could end up being pretty stressful for the passengers. Also, the self-driving obviously has to be perfect. So, this is probably not happening any time soon. It would be a conceivable way to allow much more transit on the existing roads. though.

            • Yeah, it'd be way more feasible to simply implement better public transport, i.e. metro, trams, buses, etc., then there'd be even fewer vehicles on the road; quieter too. Fewer roads would mean more open, greener spaces for people to walk around & sit in; think more trees & shrubberies, pavement cafes, shopping avenues, etc.. Imagine how much more pleasant & sociable downtown areas could be.

        Because in theory there would be multiple people in the one car at the same time, thus fewer cars and even if everyone rode solo there would, in theory, be fewer cars overall being parked etc as people would take a ride share to work/etc instead of their own vehicle. In theory.

        The reality is people still need to drive to work. It's cheaper to own and drive in than Uber both ways to the suburbs every day. Everyone can't afford to live near work in the city. I used to take the train for an hour, but still had to drive to the train station.

        And ride sharing... wow... I'm tired it once. My 10 minute solo ride turned into a 30 minutes shared trip and I only saved about $4.

              Not sure about subway areas, but I've looked at the numbers for Austin. If no one rode it barely dents the budget. Money is almost exclusively from other sources. Example, 1% of every dollar spent in the area goes to transit via sales tax. Here is the reference https://www.capmetro.org/docs/... [capmetro.org]. The main highlight is of the 781M budget, a paltry 17M was tickets. The big contributor was sales tax at 366M and 214M from grants. If people had to actually pay the full cost of mass transit, no one would use it. Maybe the numbers are way better in a place like NY or Boston where densities are higher, but I calculated the city could buy a E class benz for everyone that rode light rail that year. That's how bad the numbers are.

                That's why for some places[1] I recommend that public transport be free. It costs extra money to charge and enforce payment. You could sack/retask all the people solely involved in that stuff. No need for the extra hardware, networking and servers for charging and the departments to take care of it all. No need to pay for guards etc to handle the cash.

                If I'm going to be forced to pay for it anyway, I might as well pay less.

                As you said if few are using it the tickets contribute nothing (but there is unfairness for those who are paying and never using). If everyone is using it, it's even fairer to pay for it from taxes and skip out all the middlemen and parasites involved in "making sure people pay for the tickets".

                [1] Makes more sense for places like Singapore where only a small minority of the taxpayers would never use the public transport. But less sense where the majority never use public transport, unless the majority are still fine paying for it.

    They argue that Uber is more comfortable than walking, buses and subways. I disagree and there is nothing comfortable about having to take a ride with someone desperate to have to drive Uber but ...

    Even if it was more comfortable, the economics don't make sense? An Uber ride has got to be 5-10 times more expensive.

    Only thing I can say that it is faster and there is no parking penalty as with cars. But that only speaks to the pathetic state of public transportation here.

      Depends on the ratio of capital to operating costs. Having a nice luxury car (>$150k) that you use for 5,000 miles in a year will likely be more expensive than having a driver that uses the car for 50,000 (revenue) miles per year. Likewise if parking is $50/day at work or the airport, it is quite possible it is cheaper to hail a ride.

      After college I went about 25 years before actually purchasing a car. I might have spent a lot on taxis, but nowhere near as much as insurance would have cost over that duration, to say nothing about the capital or fuel cost.

      Then you weren't paying attention. Not only did another area of MIT [mit.edu] back in 2016 say the Uber taxi service could potentially reduce taxi traffic by 75%, even executives at Uber and Lyft [jalopnik.com] both said their taxis would reduce traffic. That was in 2018.

      Private car ownership in cities will all but end by 2025, one exec said. There’ll be “no more traffic in Boston in five years,” another said.

    • The problems with human driven cars is erratic driving, by which I mean even slight variations in speed, such as rubbernecking at car accidents, cause those waves in traffic which are responsible for jams. Automated driving, when coordinated by inter-vehicle communications that can "see" past multiple cars in front of you, have the potential to keep traffic flowing.

      And then a hacker could come in and create an epic traffic jam.

      • Hackers can hack into traffic lights. Hackers can hack the route planning algorithms in maps. Hackers can do this. Hackers can do that. Hackers can blahblahblah.
    • Yeah same here, I thought it was just supposed to make money and "disrupt" the taxi business. But then again, we've always been at war with Eurasia.

    • I don't ever recall anyone making the argument that Uber was supposed to help traffic.

      You weren't paying attention to Uber's CEO. He still repeats this lie constantly. Hell they were putting it up on billboards only a couple of years ago https://www.theguardian.com/te... [theguardian.com] despite knowing it was false.

      • As I said to the other bloke:

        Uber and Lyft executives are just doing propaganda. Not an argument to be taken seriously, and not to be taken as intentionally making the argument. They're just saying whatever investors want to hear.

        Then you weren't paying attention.

        I'm glad you have so much time on your hands to pay attention to every single claim made by companies looking to attract VCs for funding rounds.

      This one is even less believable than "uber will help traffic".

      The notion that all cars will talk to each other at light speed and know instantly where every other car is and what it is going to do is pure fantasy. The kind of thing I expect to read in a Neal Asher novel. The main problem is the speed of authentication, A.K.A. the reasons I cant tell your car I'm am ambulance and have it pull over for me.

    Who was so mentally deficient that they believed this?

    • Ridesharing would indeed help with traffic, it turns two trips into one. And it was necessary to pretend it was ridesharing so as to skip all the taxi regulation. Of course, summoning a taxi, such as via the Uber app, turns one trip into two. But if you're calling it non-taxi ridesharing then clearly it must make traffic better. It's really interesting, like with Santa Claus where society just decided we're going with this. Only this time, incredibly quickly.

        Except Uber have an actual ridesharing service called Uber Pool (not Uber You-call-a-taxi-and-pay-for-it-via-an-app-X) and the whole point of this story is that even that makes traffic worse.

    I see where the idea that buses etc. are more efficient and cleaner misunderstands part of the problem. People don't use transit merely to move from one place to another. They use transit because they need to do something that requires going from one place to another. For instance, if you need to get groceries, you need to go to the grocery store and come back with groceries. Buses, bikes and walking may be efficient and clean, but they really suck when you have to haul a load of groceries back with you. Cars that can take you directly from the store back home with your groceries are a much more effective solution to the problem even if they aren't as efficient. Solving the transit problem requires also solving the problems we use transit to solve, like getting groceries home from the store, even if that means you need to give up efficiency for effectiveness.

    Mass transit, like buses or trains, is efficient but it makes the assumption that a lot of people are going to be following the exact same route. That's not usually the case for the entire trip. You need a mix so you can use mass transit only where you can put a lot of people on a single route and use cars or something at each end where you have a wide variety of routes with very few people following any one route. You also have to have some alternate way of getting cargo (like that load of groceries) to where it's owner is going so they don't have to try to fit it on a bus or bicycle. Coming up with solutions to this isn't really that hard, the real hard part is finding solutions that don't involve redesigning the city layout or road structure overnight because that just isn't possible and doing it over time would cause intolerable disruption so that's not going to fly either.

    And then you have children, the elderly and the disabled. Bicycles and walking suck for those groups. Even buses are marginal for them. If you ignore the needs of those groups, your solution is going to be rejected before you even get finished presenting it.

      I'm reminded of something: Delivery. I remember first seeing grocery delivery proposed back in the original Death Wish movie. Lady shopped, then told the grocery store where to deliver the groceries to.

      These days, most of the grocery store chains have delivery, Amazon delivers at least some groceries, etc...

      For $13/month, Walmart will deliver to your house. Let's say it's a 10 mile round trip, at $0.25/mile*, a single trip is $2.50. Just to keep things reasonable but round.
      So, 5-6 deliveries and that fee(which also provides other services, let's value the paramount membership at $0 because you don't like star trek and whatever) is paid for.

      That's like 1.5 deliveries a week.

      That said, for bicycling: It works a lot better in many countries. After all, if you're bicycling significantly, you're a lot less likely to end up disabled. Note: My grandfather kept bicycling quite late into life, and he had significant spinal damage.

      Children: Unless they're extremely young, bicycling places is about the best thing for them. Exercise is good.
      Elderly: They can still bicycle, just slower. Maybe even not if they can have an electrically boosted bike.
      Disabled: With everybody else off the roads, the ones who have to move in things like vans can do so easier than currently. Especially if they're self driving.

      *Fuel, wear and tear, insurance, time, etc...

          Used to be that you'd do the shopping and then the store would deliver your groceries. That was well over 50 years back and I don't have any idea of the cost, if any. My parents got groceries that way. Much better then letting someone in a rush grab whatever.

          Well, I see at least three options there:
          1. Stop worrying about "quality" quite so much. It's part of why we have so much food waste in our country.
          2. Shop just for fresh produce and such in person. I could see a future where you get ~70% of your groceries delivered, which means that walking/bicycling/bussing to pick up the rest is much more manageable. Hell, if we get more dense cities, it'd be possible to have small grocery stores like what I saw when I was in germany that specialize in fresh stuff, you just go to a bigger store elsewhere for the more non-perishable stuff less often. You hit the small place up for the night's dinner and next day's lunch or such. It would help if we had more of a push for it, of course.
          2a. As dryeo said, and was demonstrated in the Death Wish movie, it's possible to do your shopping at the store THEN have it delivered. It's a service that might be offered again in the future.
          3. Pay a premium to get premium product. There's at least three different grocery chains that will deliver to me. I could experiment and see who delivers the best stuff.

        • Grocery delivery sucks if you care about the quality of non-packaged goods.

          My neighbour gets his groceries delivered. They look, feel and taste exactly like the ones I get from the store. Don't generalise.

      When I was young, late 60's, most grocery stores delivered, don't remember the cost ever being discussed but the parents, or one parent, would go shopping, come home and perhaps an hour later the groceries would be delivered.

      I don't understand. I've never driven my car to get groceries, even when catering for a large party. What's wrong with your bike? You don't have a basket on it? Let me guess, you think a "bicycle" is some hunched over carbon fibre racing thing?

      I see the little European grandma across the road from us having no problem hauling groceries home using the bus. They have these little wheel trolley things so even the old and frail (who definitely shouldn't be driving a car) can move things around with them.

      They don't, if you have the right equipment.

      For shopping by bike, a good solution is a bike rack and a pair of pannier bags. You can also hang bulky light packages, like a bag of paper towels on the handlebars. When shopping by bike, I typically did more shopping trips than shopping by car. But it is also easier to stop at a shop by bike, than by car. I can typically lock my bike much closer to the door, and load my panniers directly from the checkout stand, without needing to transfer the groceries b

    In economics, the Jevons paradox (/ËdÊ'ÉvÉ(TM)nz/; sometimes Jevons effect) occurs when technological progress or government policy increases the efficiency with which a resource is used (reducing the amount necessary for any one use), but the falling cost of use increases its demandâ"increasing, rather than reducing, resource use.

    https://en.wikipedia.org/wiki/... [wikipedia.org]

    The perception of a paradox - and this article - arise from hoping that people will take the benefit of increased efficiency in one way - by reducing traffic - instead of another - by traveling more - thus discounting the one that people actually want and choose, as somehow not a "good." But it is a good - traveling more is what people want. You hoped the safety gains from anti-lock braking would reduce fatalities, but instead it increased how fast they drive while fatalities stayed constant... OK, but now they get to travel more and go faster. Your wanting them to use the gain one way and not the other is your problem.

    • How has Uber impacted DUI? Or has it impacted crime?

      Not sure about crime otherwise, but I remember reading a study that Uber dropped DUI in at least one city by a significant factor. To the point that the police threw a bit of a fit over an anticipated rise in DUI when some regulations to drive out Uber were passed. The ease and cheapness of Uber in that city really dropped the DUI rate.

      As for "try to reduce driving or..." I'd answer with "why not both?"

    Above all, we must put in place smart regulatory and tax regimes that allow all sustainable mobility modes — including autonomous services — to scale safely and intelligently. They should include, for example, congestion fees to discourage overuse of individual vehicles.

    The only people who could possibly be discouraged by such a fee are on the low end of the economic spectrum. The rich lawyer visiting a club in his bugatti will bear the cost while hardly thinking about it. The mobility-impaired grandma struggling to pay her grocery bills will have to settle for a phone call instead of getting to see her grandkids' smiles. The people writing this regressive policy will taut a "great success" as the traffic decreases, before hopping in their own personal vehicles to catch a private jet to the next international climate conference.

    Real solutions look to make average peoples' lives better (or at least not worse). Cheap electric cars, more efficient catalytic converters, closer grocery stores. Power plants that use clean - and preferably cheaper - energy. *Not* making it more expensive to have human interaction.

    Uber Pool was so cheap it increased overall city travel: For every mile of personal driving it removed, it added 2.6 miles of people who otherwise would have taken another mode of transportation.

    And this is... a huge success! They've increased purchasing power and mobility while offsetting a significant portion of the negative externality involved in doing so. This almost certainly increases economic output and reduces poverty overall, leading to more tax revenue, which can absolutely be invested in green technologies, as well as social services.

    When bureaucrats decide to look at a single metric as if the entire world revolves around that number, they wind up implementing terrible policies, pretty much regardless of what that metric is.

      I don't follow how people being stuck in traffic in an Uber instead of spending the same time taking the bus/train would increase economic output, other then the subsidies spent on Uber (by investors), and now those subsidies are gone.
      As a bonus, using public transit often means walking a couple of blocks, creating a healthier population, which does increase economic output.

    Since a ride hailing service typically takes one point-to-point (or close to it) unlike mass transit, those choosing to use ride hailing rather than mass transit likely saved a substantial amount of time by using a ride hailing service. This time has value (and time, for an individual, is effectively a priceless resource -- one really can't buy time) and may also result in more productive work being done.

    It's also easier to work efficiently on something such as reading a document when sitting in the back of a climate controlled car taking you point to point compared to perhaps transferring twice between lines/modes of transportation and waiting for the connecting form of transportation. Doing effective work on short haul public transportation is pretty hard as one spends time standing on platforms/bus stops (sometimes in less than ideal weather), being jostled by other passengers, needing (in some cases) to keep your head on a swivel to maintain personal safety, and being distracted by buskers and crazies.
