    The fact that tolls are now directly useful to the entire public must not be underappreciated. This is good news for everyone.

      The run up to their implementation was so deeply frustrating. The sheer number of disingenuous objections. And they’ve all been proven false.

        > sheer number of disingenuous objections

        This is unfair. Nobody wants to pay more for anything. And many of the objections resulted in policy adjustments that made the programme better.

          Which objections lead to better policy?

          I didn’t say every objection was disingenuous, just that there was an incredible number of objections that were.

            I'm sure you're being honest about your intent, but a glancing read of your previous comment sounded categorical, to my ear at least, "And they've all been proven false."

              It’s hard from reading what is written how it is intended. Written communication is hard since it doesn’t encapsulate tone, emphasis, and other cues. I read “all” in this case to mean: “most of the commonly espoused objections”.

              All of the disingenuous objections. The intent of the OP is very clear, imo.

      No it’s not. NYC transit is already one of the most expensive in the world and quality is suspect. Pushing money into a dysfunctional structure doesn’t make it functional and might make it worse. A money grab from the public that goes through a maze of expenses.

      The solution was to re-structure the MTA. But that’s hard work. Politicians would rather blame the other side and just raise taxes. The people like it because they are grabbing money from what they consider it to be their oppressors.

      • jpalawaga an hour ago

        The quality is not suspect. It is one of the world’s few 24/7 systems, and there are many capital improvements happening constantly. For example, making more stations accessible and improving switching equipment to improve reliability and volume.

        This comment is typical HN “government bad can do no right” fodder. The MTA is truly a marvel in the service it provides. The only advantage it has is age, which is why it is so expansive.

        • Invictus0 an hour ago

          The MTA is billions in the red because it overpays the union workers and fails to commercialize the stations

          • amanaplanacanal 28 minutes ago

            You may not realize this, but the roads are also in the red. All transportation is subsidized out of taxes.

          • jjj123 44 minutes ago

            I simply do not care if my public services are “in the red”. Let’s make them entirely in the red, please.

            • rayiner 35 minutes ago

              The point is that the MTA is deeply in the red even though it still charges significant fares. Meanwhile, systems like the London Tube manage to recover at least their operating costs without charging fares that are much if at all higher.

        Even if the govt lights the money on fire we still get the benefit of fewer cars in lower manhattan.

        What in particular about the MTA would you change?

          > What in particular about the MTA would you change?

          Remove the diversity compliance requirement from bids, e.g. [1]. Open up bids to any firm in the nation and select winners based on cost and competence only. Subject the MTA to a forensic audit every ten or twenty years.

        > Remember kids: congestion pricing is nothing but a tariff on transportation.

        On driving. And it actually makes driving more appealing, there’s much less traffic so you can get where you’re going much quicker.

        > Instead of making public transport more appealing through competition

        Like having multiple subway systems? NYC did that already.

        • itissid an hour ago

          This is also quantitatively correct because for two people coming in from afar you might change two trains or a bus and train and each ticket is at least 3.00$(bus/path from NJ) which is 24$ minimum both ways, with more than two it would make even more sense to take the car.

          Congestion pricing brings in a toll above the 16$ you pay throu the tunnel. I think it's 18, So 34$ total?

          So you are incentivized to get more than 2 people by car. Less traffic.

        • RhysU an hour ago

          It makes driving more appealing if one discounts the best alternative use of the funds, which humans are irrationally likely to do. That driving seems better is because people suck at thinking about what else they might do with the money given compound returns on its investment.

      • eutropia 2 hours ago

        Buses got significantly more reliable as a result of reduced traffic, more ridership on subways allowed for more police presence at stations, reducing crime.

        Public transit got better.

      • Dylan16807 an hour ago

        "There is no such thing as a free lunch" is a very strong argument for tolls, I hope you realize.

        > everyone paying the tolls who now needs to engage in additional pollution-causing economic activity merely to offset the costs of government-mandated congestion pricing

        I don't think that's how economics work. People are already doing their best to generate money. Also even if that did happen, the thing you're describing as "pollution-causing" is GDP growth, which is overall desirable.

        > tariffs

        Whether a tariff is good depends on what the goal is (and whether it works toward that goal).

        • RhysU an hour ago

          If people aren't working harder to offset the tolls then they're strictly poorer as a consequence of the toll.

          • Dylan16807 an hour ago

            You can say that about any tax. Which makes it extremely unconvincing as an argument against any particular tax, since in the long term money not collected from tax A will be collected from tax B.

            (And they have the option of not driving, too.)

          • 8note an hour ago

            not strictly. the pollution has gone down, for instance, reducing future health costs, and improving quality of life.

      • 8note an hour ago

        its not a tariff because tariffs are taxes on imports. you arent paying a tax related to the value of the goods being brought over, and to the extent that new car buyers are importing cars, its neglible compared to what youre trying to draw equivalence to, trump's 30% or so tariffs.

        instead, its a toll or a usage tax.

        but also, you want the economic activity of having people in the city, not the cost of supporting their light trucks. people coming from outside of new york are very costly in terms of pollution, road maintenance, and losing real estate to parking spaces.

      They better be. No one’s rooting for the smog, but a congestion tax is pretty regressive (hurts poorer people more)

      • energy123 an hour ago

        Poor people are forced by circumstance to live in the busiest areas so they will get the biggest health benefits and many do not own cars and often do not even own a car space, so I would beg to differ.

        You can also offset the regressive nature of this taxation (if any) by putting the revenue into subsidizing public infrastructure like rail and bus.

        • seanmcdirmid an hour ago

          Isn’t it the opposite though? The poor aren’t able to live in the most popular busiest areas, and usually have to live on the fringes of the city. They might train in though. This is mostly going to benefit the rich people who can still afford to live in the city, but with rent control there are still some non-rich people in the city.

          • CGMthrowaway 39 minutes ago

            It is both. People forget that probably a third of all housing in the congestion zone is rent-controlled or public housing.

            Half of households in the congestion zone are living at or below 3x federal poverty level ($70K for a family of three). One in six residents makes $20K or less a year.

        • hammock an hour ago

          The congestion tax has far more impact on people who live and work above 60th or in the outer boroughs or NJ than it does Manhattanites. Retail, wholesale, trades, small businesses and yes commuters in these areas, which are poorer than Manhattan, suffer disproportionately

        • seanmcdirmid an hour ago

          This mostly commuters and tradesmen. You aren’t going to get your tools on the train, snd you are driving into the city from white plains or somewhere similar.

          • smileysteve an hour ago

            The alternative is the tradesmen can now apply their trade for 30 minutes more each way rather than sit in traffic (probably better overall) That, and apparently they and their kids can breathe easier.

          • afavour an hour ago

            Tradesmen pass the charge onto their customers. Commuters already have to pay huge parking fees, by comparison the congestion charge is small change.

            • CGMthrowaway 41 minutes ago

              > Tradesmen pass the charge onto their customers

                The people who are hiring tradesmen are disproportionately the rich.

              • adgjlsfhk1 27 minutes ago

                Likely not. Reduced congestion decreases transit time which can easily pay for the conjestion charge.

              Ya, definitely, I didn’t mean to imply otherwise.

          2.90 is pretty accessible

          • jkaplowitz an hour ago

            The 2.90 is even capped at $34 per week. Then there's the 50% discount for low-income NYC residents who qualify and apply for the Fair Fares NYC program, or for anyone regadless of residence who qualifies for reduced fares through age or a qualifying disability.

            Both of these numbers are changing in early January to $3 and $35 respectively, but same idea.

            Still, some European countries like Germany offer far cheaper than this, while others like the UK are probably pricer. NYC public transit gives very good value for the US at least.

        Many things hurt the poor more, because there are many things that the poor do that have negative externalities that cannot be compensated for by the productivity of the poor. Strict enforcement against violent crime is pretty regressive in that more poor people are incarcerated when this is done. Others are that strict enforcement of traffic laws is pretty regressive; paid parking is regressive; as are fares for buses and trains. Requiring a minimum number of signatures for a ballot proposition is regressive. Allowing more expensive cars to incorporate more advanced safety features is regressive. Requiring grant applications to be carefully written is regressive. As are minimum flying requirements for pilots. DoD medical standards for soldiers are regressive. Officer ASVAB score requirements are regressive. Surgical requirements. Drug approval requirements.

        In fact, anything that requires a standard of performance will be regressive. We don't have to subordinate all goals to regression avoidance. In fact, no functioning society does that.

          > Officer ASVAB score requirements are regressive

      • tootie an hour ago

        I actually doubt it's very regressive in NYC. Also, you're still only counting the price and not the cost. The benefits are likely tilted towards the poorest residents who absorb the most costs of congestion in terms of both pollution and road safety. That's just an educated guess but it's very plausible.

        • masterphai an hour ago

          A charge on the marginal driver looks regressive if you only examine who pays the toll, but not who’s been paying the externalities all along. Once you include the benefits - faster buses, cleaner air, better reliability, and the ability to reinvest revenue into transit - the incidence flips pretty quickly.

          We’re basically shifting costs from people who can’t opt out of congestion to people who can. That’s about as progressive as a transport policy gets.

          No, individualized point to point travel is better. I just got back from Tokyo and Taipei, which have transit systems better than any European country. And it was still faster to Uber everywhere.

            And how much did that cost? You can get around Tokyo on the subway system for $5 for an entire day, and it's a profitable system that largely does not rely on taxpayer subsidy.

            And how fast would it be if Tokyo and Taipei's trains weren't handling 80% and 40% of trips, respectively?

            If you reduce Tokyo's 80% trip usage rate down to 5% like many American cities, that means for every other car on the road in Tokyo you'd now see 5 cars instead. How's that Uber ride looking now?

    There was a study published about how much air pollution dropped in NYC during the COVID lockdown. PM2.5 was found to have dropped 36%. However with more robust analysis, this drop was discovered to not be statistically significant. I would caution anyone reading this who is tempted by confirmation bias.

    What did it do to GDP? (Sincerely asking)

    • dataviz1000 an hour ago

      I wonder myself this too. Would people have to say "If NYC was a country would its GDP be 11th largest in the world compared to being the 12th largest GDP in the world like in 2024?"

      What we can quantify is the economic impact the San Antonio River Walk has or the impact the Atlanta Beltline has which is billions of dollars in added economic activity. Based on those examples, likely it will increase the NYC GDP by millions if not hundreds of millions. We can prove with dollar amounts getting rid of cars in these cases increase the GDP by billions but in NYC they are only decreasing them so probably won't have the positive impact completely getting rid of cars does.

    • petesergeant an hour ago

      No city has reliable data on this for a fleet of reasons. The high quality data tends to show little effect on retail foot traffic, slightly more reliable commute times, and then the wealth of health benefits. Linking this to output seems to be beyond economists for cities that have done something similar (London, Stockholm, Milan, etc)

    "average daily peak concentrations of PM2.5 dropped by 3.05 µg/m³. For context, background pollution levels in the region typically hover around 8-9 µg/m³, making this reduction particularly significant for public health."

    I think that the numbers are already low enough that the drop is actually not very significant, at all. Is there any data that shows better health outcomes at 8 vs 13 for PM 2.5 levels? From my understanding adverse health outcomes come at exposure over the long term to higher levels like 30 minimum

    For context I have several air purifiers in my home and I'm all for better air quality but the percentage difference makes it sound like a much bigger drop but when these numbers are already so small I just am skeptical it really makes a difference...

    • hn_throwaway_99 an hour ago

      This is not accurate. The WHO (which recommends lower levels than US authorities) recommends an annual PM 2.5 level below 5 µg/m³: https://www.c40knowledgehub.org/s/article/WHO-Air-Quality-Gu...

      But more importantly, when it comes to PM 2.5 levels, there are really no safe levels, the risks are just dose dependent, so lower is always better. In a city the size of NYC, lowering air pollution by 20% means a significant decrease in effects.

      To give a good analogy, driving a car on the US is still quite safe, most of us take that risk, but still, thousands die annually from car accidents. A one fifth reduction in deaths from car accidents, even from its current low level, would be a major deal. In NYC, around 1 in 20 deaths is linked to air pollution.

      • weird-eye-issue an hour ago

        That's the strictest "policy" I've seen and I was asking about any specific health data not WHO guidelines

        "In NYC, around 1 in 20 deaths is linked to air pollution."

        A difference between 8 and 12 PM 2.5 levels won't change that

        • hn_throwaway_99 20 minutes ago

          > A difference between 8 and 12 PM 2.5 levels won't change that

          Yes, it will, and that's the point I was making.

          There are some things that have no harmful affects below certain concentrations, in that they are not toxic at low levels. PM 2.5 particles are not one of those - they are toxic at all levels. It's quite similar, in this context, to ionizing radiation. There is no safe level of ionizing radiation - every X-ray you get will slightly increase your chance of getting cancer. Of course, in the risk/benefit analysis, the risk is low and the benefits for medical X-rays are high.

          It's the same with PM 2.5 pollution - every percentage reduction results in fewer health effects and related deaths. It's fine to argue that some level of pollution is worth it to get the benefits of industrialization, but it's simply false to say a reduction from 12 to 8 PM 2.5 levels won't reduce related deaths.

    It's frustrating how poorly most people understand economics and the distinction between price and cost. Everybody in the world is being asked to blithely accept the massive unpaid costs of motor vehicle usage. This is a tiny step towards recouping some of this costs. Roadways, parking, collisions, pollution, noise have all be costs born by all of us. And in NYC that's a load of non-drivers. We should be adopting all sorts of policies to pass those costs on to drivers.

    People panic over the thought of free buses when we have millions of miles of free roads.

    The article says "average daily peak concentrations of PM2.5 dropped by 3.05 µg/m³. For context, background pollution levels in the region typically hover around 8-9 µg/m³, making this reduction particularly significant for public health."

    But 8-9 was already considered a safe level: "Most studies indicate PM2.5 at or below 12 μg/m3 is considered healthy with little to no risk from exposure. If the level goes to or above 35 μg/m3 during a 24-hour period, the air is considered unhealthy." (https://www.indoorairhygiene.org/pm2-5-explained/)

    So, good job on reducing pollution, but you already had very safe levels (well, the article doesn't tell us what the old "peak concentrations" were). Since the levels were "little to no risk", the claim of "significant health benefits" (i.e. reduction in disease or death) should be challenged.

          I'm confused, if you lived in Westchester and were parking by Columbia why would you be in Midtown? Mind you, it's still like $14-$22 to cross the GWB and if you parked by Columbia after driving down from Westchester you don't have a congestion charge to worry about.

            I’m not sure, I’m a bit hazy about the names, it was a dormitory, I never actually saw the school. The dormitory wasn’t on campus. We were interning at IBM Hawthorne at the time and my friend was living at a Columbia dorm and commuting. Sometimes when I took the train the nearest train line stop (to get back to Hawthorne) was Harlem.

              I get it, remember the congestion zone isn't the entire borough of Manhattan. It's just below 59th street. And, if you were driving down there, good luck finding parking in the literal densest place on planet earth during work hours (187k people/sqm). Driving in the congestion relief zone is not a right.

              (Also, this thread's root was "regressive tax affecting the poor" which I assert again, is just a silly mischaracterization)

          Columbia is over 40 blocks north of the congestion zone. You’d be able to do the exact same thing today.

        I like walking around new cities, but a lot of people are car life types

          Congestion pricing makes driving in New York better. Broadly speaking, the tendency for someone to have a problem with the scheme is proportional to their distance from and inversely related to the amount of time they've ever spent in New York.

          But we're talking about New York City here, not Kansas. Specifically the congestion zone which during the work day is the most congested place in the world (187,500 people/sqm).

        We did perfect their mass production, and it propelled us to the world's largest economy. The only country with better GDP growth over the last 100 years is Japan, and that's in large part because they perfected the manufacture of cars themselves.
