Vehicles with city-issued non-profit parking placards are 88 percent more likely to be "Super Speeders" than any other vehicle with speed-camera violations. buff.ly/lIiw6b5

Really enjoyed starting my day with this post. The drop in the grid’s carbon intensity is incredible. “two decades ago the average carbon emissions per kWh were around 500 g CO2 / kWh. In 2025 it was 121 g CO2 / kWh.”

NEW BRIGHT SPOTS: Even on 100% gas power, heat pumps cut emissions by ~48% and EVs by about half. The authors of an “electrification doesn’t cut emissions” paper made a series of compounding mistakes and used misleading assumptions. Here's why. janrosenow.substack.com/p/heat-pumps...

The craziest thing to happen to American politics in my lifetime was the Midwest looking at the South, historically the most poor and backwards part of the country that was the punchline to every joke, and deciding they wanted to be just like that.

“I’m not willing to keep our teams active in the field until I know that all protocols are being followed with respect to customer interactions,” said the MTA's Janno Lieber on Thursday. buff.ly/Q9WCbjz

These are clearly felony murders. Trump and Pete Hegseth went out and intentionally murdered innocent fishermen, with help from high ranking US military officers.

This video camera study showed that less than 5% of people on bikes broke traffic laws while riding bikes, yet 66% of people did so while driving. And perhaps even more importantly, if you REALLY want even MORE bike-riders to obey laws, build more protected bike infrastructure. Via @carltonreid.com

But most of the people who voted for this when they voted for Prop 13 have died of old age, and the levees didn't break while they were still alive, and in the meantime they had a lot of extra money to spend on stuff, so the system worked.

This guy was caught on video committing one of the worst road rage incidents I've ever seen, plowing into a group of riders—and then he left the scene. Seriously, fuck the Atlanta Journal-Constitution for framing him as some sort of a victim. You are complicit assholes. www.ajc.com/news/2026/10...

The inner Inland Empire was built around the streetcar system and has the skeleton of good urbanism that decades of car-oriented sprawl can't erase. With much much better Metrolink service and more people-oriented streets, it could be very livable.

I bet most people would be surprised by these charts showing the Graying of Silicon Valley. I think people would especially be shocked by the San Francisco chart of Children vs Seniors, given media portrayal and pop culture.

The generation that got to buy cheap houses thanks to a postwar construction boom, then blocked new housing construction to juice their asset values is now whining that they have to pay taxes on their unearned wealth. Just breathtaking selfishness.

Karen Bass glonzo-posting about how Nithya Raman supports data centers is hilarious to me because Los Angeles is home to a ton of genuinely terrible industrial pollution sources, many of them near residential areas.

Who the law binds but does not protect. Who the law protects but does not bind.

“I don’t want AI to replace artists and writers” is a humanist sentiment but “I don’t want robots to replace delivery drivers” just comes across as regressive to me.

I've never struggled to believe reports of bad behavior by cops because even in my very limited interactions with them in my life, they've often been remarkably unprofessional, rude, and threatening. Just suggested one shouldn't block the only accessible sidewalk and he called me a p*ssy and more.

$70,000 a spot to bury it underground

It’s even more ridiculous at night

As usual, zero consideration for where bikes are supposed to go when you close a bike lane. Of course 2 car lanes are kept open.

RAND finds that Santa Monica projects take about 5.7 years from application to final permit. Comparable West LA projects take 4.9 years. Most of the gap comes from the approval and permitting stages, which the city largely controls. www.smdp.com/housing-rand...

Yikes...the National Fire Sprinkler Association published a blog post in 2025 about Maryland’s 2024 Fire Fatality Report that appears to have been written with ChatGPT and, as far as I can tell, hallucinated some major findings nfsa.org/2025/07/29/m...

California's recent political shift toward thinking it's bad for violent drivers to kill and maim people is going to have to spend ~ a decade in conflict with the massive state/local governments and institutions whose purpose is to help violent drivers kill and maim people. It's gonna be wild.

Mayor Bass's statements on the pedestrian death has huge mayor in hot dog costume vibes. You want to find who is accountable? Maybe start with the mayor who has blocked safe street projects throughout the city.

*No one* wants speeding cars in front of their house/apartment! Let's use NIMBYism for good, and push down speeds on every residential street in the US.

Holy shit.

Everyone wants someone else to plan dinner parties & invite them.

He releases this even with Third Way, a centrist org, telling dems to stop doing this. bsky.app/profile/erin...

There is a moment at the very very end of Abdul El-Sayed's podcast with Ezra Klein (book recommendation section) where he talks about the idea of "speaking truth to pain" and this will be staying with me for an extremely long time. www.nytimes.com/2026/09/25/o...

“Paris has embarked on a grand transformation, planting 155k trees, adding hundreds of kms of bike lanes, pedestrianising 300 school streets and banning cars from the banks of the Seine. Parking has been turned into green space…Fewer parents fear their child being run over when they walk to school.”

For those that might have missed 4th grade math class, if you keep passing the same cyclist then you are going the same average speed as them and you gain nothing from making a dangerous pass.

I am not going to lie. I absolutely LOVE passing drivers multiple times, especially if they punish pass me like I am slowing their important journey. Driving aggressively in most urban and suburban zones has zero upside and they fully deserve to be reminded of that.

“We believe [these age verification laws] burden adults’ rights to access lawful speech, that they can destroy people’s ability to be anonymous online, and that they are privacy and data security disasters waiting to happen,” EFF’s @aaronmackey.bsky.social told @penncapital-star.com.

As a Californian, I'm eager to confront the REALITY that building mansions on the beach is not a viable long term housing or having a beach solution. The Edge of California Is Falling Into the Ocean - The Atlantic share.google/OJ1O32dZPQ7L...

if you are driving and you want to let a pedestrian know you are stopping so they can cross, the best way to do that is by stopping. Not driving at them while making impatient gestures.

Photo from Reddit of today’s Critical Mass. There are hundreds of cyclists in this photo and only about 40 people in cars. Yet both groups are taking up roughly the same amount of road space.

Susan Collins is blatantly corrupt. Hollywood couldn't write this in a script.

I told my PT my left elbow hurt. She said, "that's the side the lady hit you with her car, right? Think that may have something to do with it?" 🤦 Old ladies that shouldn't be driving are going to kill us all, and it's so normalized we'll just be sadly nodding while they run us over.

"Isn’t it obvious that selfishness on the road changes us as a society? The belief that a driver should be allowed to do whatever they please, regardless of the impact on others, mounts the pavement and travels deep into our lives." Via @georgemonbiot.bsky.social

Athletes are among the most susceptible to snake oil in my experience. Tom Brady is a prime example in American football.

The meme I started is being replicated and now is using Seattle area coffee shops. So proud

Wrong. This is an ag policy problem. Residential water use is a pittance compared to the water resource demands of the cattle industry.

Steel bollards for terrorist attacks that almost never happen, plastic posts for bicyclists who get hit every day.

Imagine how funny it's going to be when every lineman in a football game is betting everything on the other team, though. The farce!

Amtrak didn’t tell us about this exposure, so heads up: if you took an Amtrak train last week through Chicago or anywhere on the Southwest Chief, Coast Starlight, or California Zephyr routes like we did, you may have been exposed to measles! Please let the train people in your life know about this
