Obviously I talk a lot about bike/ped safety.
But something that is really crazy is how much less safe you *in a car* since 2010.
In spite of all the additional safety technology, vehicle occupants are less safe today than they were 15 years ago.

If there's anyone who has worked harder to flip the script on the NIMBY history of Marin than Jenny, I don't know them.
Listen to the reformers: state law gets the goods.
(And you still need people like Jenny holding cities' feet to the fire)

I've done a lot of housing advocacy in Marin. We have 9,000 units in the pipeline. We'd have nothing without the state-level reforms.
I wrote about state-level ADU reform and the differences between @strongtowns.org and YIMBYism. www.maxdubler.com/blog/2025/11...

I'd been hearing that something like this was in the pipeline, but it's definitely going to be a bummer.
Our Radwagon isn't the best bike in the world, but it has been a total gamechanger in how we get around Berkeley (and the Rad shop is walking distance to our house).

Most of this is just Baumol's cost disease, and then you're like, "wtf is going on with college textbooks?"
These figures are in nominal terms, which is absolutely wild. Half the things listed here got cheaper or stayed the same *even without adjusting for inflation*.
Pretty much all affordability discourse could benefit from just posting this chart.
If you're in the better off America, all the luxury goods you want in excess are for the most part much cheaper. If you're in the poorer America, most of the shit you need to live/grow is more expensive.

There was an Effective Altruism/AI Safety meetup in my local park, and now I'm listening to one of the attendees try to explain it to a normie parent just here with her kids.

Lord knows I hate people texting and driving.
But nothing gets me *steamed* like seeing someone driving a box truck with both hands on the phone.
Imo that should be an automatic CDL suspension.

Shabbat shalom to everyone except the lady in the electric VW SUV who screamed "FUCK YOUR BICYCLE!" as she blasted past us on the bike boulevard, almost hitting a couple scooter riders in the process.

I know it's not surprising anymore, but it's still shocking to see US police beating people in the streets for...celebrating a world series win.
Of course @lataco.bsky.social @shoton35mm.bsky.social has the definitive account of what unfolded before and after Saturday’s victory — which illustrates over and over again how LA is completely unprepared to handle celebrating fans

A nice little Bay Trail gap closure project was just awarded funding in East Corte Madera.
This project extends a multiuse path along Paradise Drive, connecting an existing path and a wide sidewalk.
This means nearly all of Paradise Drive will have a multiuse path (or something very close).

Anyone who has ever done school drop-off in a car knows that you would actually be able to do it faster by horse.
Car brand BYD's new SUV ad pokes fun at people walking and cycling, comparing them to Horse & Carts.
It joins a long list of car ads that sell a false promise of convenience and aspiration while punching down at sustainable transport modes.
So I made it a bit more realistic...

There had better be trials. And not just for the low-level thugs carrying out these orders, but for everyone up the chain of command.
If we get past this, the solution isn’t to pretend it never happened and invite Stephen Miller to Harvard’s Institute of Politics.
It’s trials w real punishments.

A family friend was telling us about what her husband shared about his experience in Broadview before he was deported back to Mexico. She's been sharing to friends and family because she's just in disbelief & horror what her husband told her. She wasn't able to talk to him until he was in Mexico.

So much of our energy policy ignores the fact that there is a trillion trillion trillion ton fusion reactor right here in our solar system that will give us free power for the next 4ish billion years.

Regular reminder that we install signal poles and light posts with breakaway bolts *with the explicit purpose* of allowing cars to cleanly drive through them.
This results in the regular wiping of pedestrian off sidewalks, who might imagine that they are protected by nearby infrastructure.
