Born in Berkeley. YIMBY. Cars ruin cities. Also, too, Jackal.

A story of cause and effect: Last November, Ontario banned cities from using speed safety cameras to issue tickets. Reckless speeding immediately surged in Toronto, Ottawa, Guelph, and cities throughout the province. A 🧵 about my latest in Bloomberg (gift link)

What Happens When Speed Cameras Get Shut Off

In 2025, Ontario banned automated traffic enforcement. Now the number of drivers exceeding the speed limit has surged, according to traffic data.

Notice how he doesn't even mention parking, despite the containers being located along the curb. Other mayors would talk about the tradeoffs and say, "Look, we know New Yorkers like their parking." Not Mamdani. He keeps the focus where it belongs: on cleaner streets.

Now this is the kind of trash talk we can get behind. We’re containerizing neighborhoods by taking trash off our sidewalks and allowing mid-size buildings to trade in their wheelie bins for a bigger, better, cleaner alternative: Empire Bins. It’s time to put a lid on it, New York.

But it seems to me that most people, when it comes to food, begin with what they want to believe - my diet is right and ethical - and look for evidence to support it. I understand this: it's literally a visceral issue. But we have to try to get beyond what we want to believe, hard as that is.

Somebody pointed out the precedent a O’Keefe’s proposal will likely set: NIMBYs and other conservative strains could kill projects to improve public safety and fulfill the city’s goals of they just complain and stall long enough. Any decision the city of Berkeley makes only counts they like it.

If you can go to the city council meeting tomorrow night to show O’Keefe, Blackaby and other Berkeley city members that a safer Hopkins is good for all of Berkeley. If you can’t, take a minute to send them an email thanks to @walkbikeberk.bsky.social actionnetwork.org/letters/tell...

i think people look at homelessness as a relatively new phenomenon and reason backwards to think that in the Before Times, poor people must've all been able to afford houses/their own apartments etc. Most of the housing types the poor used were actually just outlawed (boarding houses, SROs etc)

The two hardest and most unforgiving facts in housing policy are that it actually costs a lot of money to build new homes and that the rents that poor people can afford are not enough to pay off the cost of construction.

Hopkins was my first big bike battle after moving back to Berkeley. The initial Hopkins Council referral, from 2018, is itself old enough to ride a bike. If this very reasonable compromise doesn’t work, my fall-back plan is car-free Hopkins.

Obi-Wan Kenobi saying, “IF YOU STRIKE ME DOWN, I WILL COME BACK WITH A CAR-FREE HOPKINS PLAN”Justin Timberlake’s character in The Social Network, saying, “YOU WANT A PLAN THAT'S REALLY SAFE? CAR-FREE HOPKINS IS *REALLY* SAFE.”The debate guy meme sitting with a sign that reads, “CAR-FREE HOPKINS IS A PLAN THAT IS *REALLY* SAFE. CHANGE MY MIND”

The moment a Russian nearly kills his partner. It is reported that the average lifespan of a Russian soldier at the Ukraine front line in 2026 is now shorter than that of the common house fly.

Because we treat each intersection as distinct, and require frequent injuries/deaths at *that* intersection before we intervene, the pattern of "bikes crossing a high-speed/-traffic road" does not get the attention or work needed. Again and again, these specific intersections cause more trauma.

States do not need to contract with companies owned by oligarchs who seek those states' demise. No matter what services an anti-democracy oligarch's company provides, it is not in the national interest of any democracy to send them money. Some in Europe apparently realizing that. And acting on it.

France has joined Germany in cancelling their Palantir contracts, becoming the 2nd country in as many weeks to do so — the UK appears poised to follow suit AOC: “Immediately investigate Palantir — (Thiel’s) secretive data mining company that has weaponized information against immigrant communities”
