"To understand the potential health risks from tire pollution, researchers exposed human immune cells to a mixture of tire-derived pollutants as well as 6PPD-quinone on its own. The mixture caused rapid cell death, among other harms..."

Not riding a bike is MORE DANGEROUS than riding a bike without a helmet.

I'm over here just firing on all cylinders

Nothing gives me more hope for America than walking the streets of NYC. There's bikes everywhere, pedestrians exerting dominance over cars, people everywhere, shops everywhere. The subway! Every type of human being, all mixing together to make something stronger and better than its parts.

Portland Oregon just does not need as many five lane roads as it has. One could even argue it barely needs any.

What's the best bike shop in Brooklyn, Manhattan or NYC for kids? Looking for new helmets for my 1 year old and 3 year old and pedal bike for my 3 year old.

We built cages and called them cars.

Some ideas for second term of @mayorwu.boston.gov: -bulldoze Boston Common & the Public Garden & replace it with a multi level parking garage -eminent domain South Station & Back Bay & make the T terminate their dirty commuter rail outside of Boston -bulldoze the Esplanade & widen Storrow Drive

"Those who use the roads should pay for the roads." "In fiscal year 2025 alone, the gap between what drivers paid in and what roads cost hit $30.6 billion."

At this point it is safe to assume that @wutrain.bsky.social has either been kidnapped and replaced with an evil doppelganger or is being actively and several blackmailed. Nothing else makes sense but we have to help #FreeTheWuTrain www.reddit.com/r/bikeboston...

"Public transit needs to be viewed for what it is: a tool that can save someone up to $15,000 per year. There is no other cost saving tool at any government’s disposal as powerful as #publictransit." @michaelhall.bsky.social @movementyvr.bsky.social #bcpoli #bcndp

Not only do kids deserve freedom of movement we should frankly prioritize it. Streets that are safe for kids are safe for everyone else too. For too long "adults" have prioritized only speed and only viewed transportation through the lens of "grown ups" and we've all suffered for it.

One thing that's cool about the Mamdani bike bus is that it goes beyond just centering bicyclists (and pedestrians) and focuses on the fact that children have a right to move around cities safely without fear of cars. Kids deserve freedom of movement.

Fucking love this guy. Can we get him to give out trainings to other mayors on how to be the GOAT?

My least popular (and most correct) view is that cars should be automatically limited to the local speed limit. Put the pedal to the floor and you still can't go over 25mph in a residential area. (15 in Manhattan btw)

Why is it that in New York City, one of the most expensive pieces of land anywhere, someone who can afford a car gets to park it for free but someone who takes the train, something that benefits everyone, has to pay $3 each way for the privilege?

My last name means money, so I made a website that asks for money and offers absolutely nothing in return. Finally, a business model with no hidden agenda because there is no agenda. mylastnamemeansmoney.com

Cars cause eczema. www.dermatologytimes.com/view/scienti...

Banning able bodied 16-55 year old males from driving cars for non-commercial reasons would solve about 80% of the problems with the USA.

NYC should annex the rest of the country.

Nobody in this administration has seen a single episode of Rick Steves and it fucking shows.

To paraphrase what the former Mayor of Bogotá, Enrique Peñalosa, famously said: "A well-designed city is not a place where the poor have cars. It's where the rich use the bicycle."

It’s really important that #Vancouver’s Downtown Business Association, who were originally against bike-lanes, are now among their most vigourous supporters, because of ACTUAL EVIDENCE that they’re better for downtown business than any street parking they replaced. Safe bike-lanes mean business.

“In Utrecht, the bike is not an end in itself. It is a means to create a liveable, healthy, climate-friendly city for all. The success can be admired in the inner city. It is lively and yet quiet at the same time. Here, it's noticeable: Cities aren't loud; only cars are, and they play no role here.”

STREETS ARE FOR PEOPLE

My walk from the subway stop goes through a few stop signs and it is incredibly rare to see a car stop.

Is your city Bicycle Ready?

The problem with PBOT and the city's approach in general to East Portland roads, isn't a lack of attention or investment. It's that the projects they do build are way too compromised (bcuz politics), too sympathetic to drivers, and are lacking in physical protection for bikers/walkers.

In New York City they put the bike lanes on the left side of the road because you want the fastest vehicles to stay to the left.

If every single bicycle in the world disappeared cars would be just as slow as they are today. If every single car in the world disappeared bikes would be multiple magnitudes faster than they are today. A 40 minute urban bike ride would go down to 20 minutes.

So we moved to Brooklyn this weekend. Went on my first bike ride longer than going around the block today & it was pretty incredible. Perfect, absolutely not. There's way too many cars in general & parked in bike lanes but overall I saw tons of bikes, felt like I was in a bike city & loved it.

This reddit comment in response to the question "is it crazy to bike commute 6 miles?" is exceptional: "What’s crazy is sitting alone and angry in a metal box for over an hour a day." So succinct yet fully captures the mental health problem cars create. www.reddit.com/r/bikecommut...

If Boston simply stopped trying to appease cars, an incredibly selfish and inefficient mode of transport, it could transform itself into one of the world's greatest cities. The bones are there, it's an amazing walking city, biking is already the fastest way to get around but the T needs expansion.

Ever ask yourself why so many climate scientists are also cyclists?

American cities were not built for cars. They were bulldozed for cars.

This is what Storrow Drive should be - except even better. We have more space, we put in a train that runs along storrow, add dedicated wide bike lanes, even little coffee shops could dot the land scape so ppl could enjoy the waterfront with a cup of their favorite brew

Very open to any comments, suggestions, feedback, feature requests or anything else about PeopleStreets News. A few things I'm thinking of adding soon are: -ability to make image/video posts -subscription option to get notified about new stories -comment formatting news.peoplestreets.live

Made a thing for the urbanism, bike, pedestrian, transit community at news.peoplestreets.live. The quick summary is it's basically a news aggregator for urbanism news where you can submit stories and vote and comment on them. My hope is this site can become a way to share news far and wide!

Just stumbled on this picture of me from four years hacking the coffee machine to work after I broke the carafe and it feels like the right thing to share right now.

AI: Automated Idiot. 🤦‍♂️🤣

I think we can change the world by having protected bike lanes and secure bike parking everywhere.

Update: ODOT will not be moving forward with my radically non-radical idea of improving urban mobility by NOT expanding freeways as Director of Urban Mobility. Alas. 😞

Asked AI to estimate what the cost of gasoline should be if we included all negative externalities: (Costs per gallon) Tire Pollution: $0.10 Car Accidents: $1.40 Air Quality Impacts: $3.40 Climate Impacts: $10.90 Direct Environmental Costs (Gasoline): $3.80 Total Estimated Cost: $19.60 per gallon

If you're going to complain at least come with facts and truths instead of the bullshit most maniacal motorists spew about bike lanes. Or yes just STFU.

The solution to poor driving is rocks Parking on the pavement? Put some big ol' rocks in the way Are cars going too fast? Cover the road in little bumpy rocks Street too wide? Big pile of rocks for cars to go around Need a bike lane? Line of chunky rocks to keep cars away Rocks 👍 🪨🌳🚶🚴‍♂️

I did some field research awhile back to see how the Dutch do bike lanes in industrial areas and—folks—they're better than the shit we have in the city.

So I applied to this ODOT Urban Mobility Office Director job figuring I'd be insta-rejected but made it past the first screen! What qualifications do I have to direct widening highways to reduce congestion? None, but neither does anyone else! But you bet I could increase urban mobility! #urbanism

People think Portland, Oregon is a progressive place that is bike friendly BUT WE TAX BIKES. Sorry for yelling but it's absolutely insane, counter-productive, regressive, anti-bike, anti-climate and hasn't stopped the '“bikes don’t pay their fare share.”' cries. We need to get rid of the bike tax.

Economics could save the world, if we just let it! Negative externalities are harmful side effects of economic activities but taxes are a powerful tool to reduce these harms. We simply lack the political will to implement these effective & CAPITALIST solutions. #climate adamp.com/economics/ef...
