While walking my son to school a couple of weeks ago, I noticed something odd happening on Court Street, a major thoroughfare that runs through our part of Brooklyn: A lane of the street was being removed, to make room for a protected two-way bike lane.
The traffic revolution that’s making cities cleaner — and happier
More cities are finally choosing bikes over cars.

As a father who would like to see his son bicycle more but lives in constant fear of him being pancaked by an SUV while riding in Brooklyn’s packed streets, I was elated by the change — but also surprised. Even in Brooklyn, one of the most densely populated and walkable places in the US, about half of households own a car — and I can tell you from experience, they are very territorial about their right to drive them.
Yet here was my own neighborhood, taking away a lane for cars and giving it to cyclists. It’s part of an effort spreading across New York and cities around the US and the rest of the world, to carve out meaningful, safe space for residents who prefer to get around on two wheels rather than four. And it’s one of the best, most optimistic movements in urban development, one that can make cities cleaner, quieter, and more sustainable.
Two wheels good; four wheels bad
In central London, as the Economist wrote recently, bikes now outnumber cars two-to-one at peak hours. In Montreal, more than a third of people cycle at least once a week, and use of the city’s bike-share program has doubled since 2019. In Copenhagen, bike trips make up almost half of all commutes. And New York has built the world’s largest bike network, with 1,550 lane miles, 555 protected lanes, and more on the way. With its Citi Bike program, NY has the largest bike-sharing system in the US.
How did we get here? Not by just painting bike lanes on open streets and hoping for the best, but by building routes in cities where cyclists can actually cycle, with safer designs that make biking the obvious, low-stress choice. Cities are knitting together:
- Parking-protected lanes that physically separate bikes from moving traffic. That turns urban cycling from an extreme sport into something you can safely do, whether you’re 7 or 70.
- Protected intersections that make car turns safer and improve sightlines so both cyclists and pedestrians are more visible to drivers. Such changes make it far harder for cars to swoop through rapid right-hand turns, which can be especially dangerous for cyclists.
- Traffic signal tweaks such as leading pedestrian intervals (LPIs), which give pedestrians a several-second head start before lights turn green, as well as bicycle-specific traffic light phases. In New York, LPIs cut total pedestrian injuries by about 33 percent across more than 6,000 intersections between 2013 and 2018, while cities like Seattle are rapidly adopting “no turn on red” policies that can protect both cyclists and pedestrians.
In bike-obsessed Europe, street redesigns have gone further. The Belgian city of Ghent’s 2017 plan didn’t just add bike lanes; it specifically filtered auto through-traffic out of the center of the city, nudging drivers to the ring road and reserving inner streets for access by cyclists and pedestrians. The result has been a shift toward more sustainable modes of transport and calmer streets altogether — what you might just call “livability.”
Lastly, the boom in e-bikes, which offer enough electric pedal assist to make an ordinary cyclist feel like Lance Armstrong minus the blood doping, has expanded who can cycle and where, though they can come with real safety concerns.
The benefits of biking
Start with cost. Swapping out a family car for an e-bike can save thousands of dollars a year, especially as the cost of owning a car has generally been increasing. That switch makes even more sense as cities add secure bike storage sites.
Taking a bike over a short trip as opposed to a car can reduce carbon emissions by 75 percent. Central London, which has combined congestion charging with new cycle paths and dockless bike sharing, has seen conventional air quality improve significantly. And silent bikes don’t contribute to urban noise pollution the way cars — and my particular bête noire, motorcycles — obviously do.
Then there are benefits to health. One UK study linked cycling to work with lower all-cause mortality, as well as lower mortality from cardiovascular disease and cancer. A 2021 meta-analysis found that all-cause mortality declined as hours of cycling rose. These are correlations, and someone who makes a point of biking to work is likely already pretty healthy. But it obviously beats sitting in a car.
Biketopia
Even the most cycling-forward cities like New York are miles (or kilometers) behind top European cycling cities like Copenhagen and Amsterdam when it comes to bike-friendly infrastructure. And like literally every other issue in the entire country, cycling is already becoming polarized in the US, where drivers are loath to surrender their primacy.
While much of that has to do with a car-centric American culture, there are real growing pains as cycling ramps up. Pedestrians already on the watch for cars now have to look out for bicyclists — not all of whom follow traffic laws. E-bikes present a particular challenge. Because they go faster and have more mass, they’re more dangerous both for cyclists themselves and for pedestrians in their way — especially illegal, fast e-bikes that are more moped than bicycle. That is a real problem, and one that could end the cycling renaissance if it’s not addressed.
But while e-bike collisions get a lot of attention, they pale next to the sheer carnage we take for granted on our roads, where over 40,000 people died in motor vehicle accidents in 2023. The number of pedestrians killed by cars is now over 7,000 a year, a number that has been rising for more than a decade. Yet no one is calling to ban cars.
When cities build bikeable routes that feel safe for an 8-year-old like my son, adults who could be in cars will ride bikes, too. And when more people ride, the benefits — safety, clean air, quiet streets — compound.
On Court Street here in Brooklyn, that new protected lane already looks ordinary. That’s the point. Ordinary is how culture changes lives. I still worry about my kid on a bike, because I’m a parent. But I’m also more optimistic than ever, because the street outside his school is quietly teaching him — and his city — a better way to move.
