In which I explain one of the many WWII myths that I still see coming up even in 2026. That the intact Zero captured in the Aleutian Islands in July 1942 had a great deal of influence on the design and testing of the Grumman F6F-3 Hellcat. Turns out that wasn't really the case. My latest⬇️

Honestly feel like cars have a sort of Bilbo & the One Ring "after all, why not? why shouldn't I keep it?" quality. Someone I know rented one recently & while they had it they were like "I should get a car; I need a car" & as soon as they returned it they were like "I mean, literally why tho lmao"

Hi friends: I haven't written an article in three months. Here's why, and how my experience as a caregiver to a person I love with a disabling, terminal illness upended most of what I think about car dependency and transportation reform.

The Houthi-aligned Bani Hashish tribes are massing in preparation to “liberate” the remaining Yemeni territory outside Houthi control. It’s a sea of Toyotas with mounted machine guns. I think this is what we should mean when we say Toyotathon from now on.

carbrain traffic "engineers" are why this pedestrian crosswalk (really car infrastructure, to help drivers avoid murdering people who have a right to cross) is flat with the road, to optimize vehicle flow and comfort, while pedestrians have to step down into a huge puddle that gets their feet wet
picture of a crosswalk. A huge dark truck just passed. It's raining heavily. There are huge puddles on both ends of the crosswalk at the curb cuts.

But if traditional media don't cover Mamdani's good government work, it reduces the chances he will get a political return on this, and so he is incentivized to move away from it. If you are a Mayor not getting coverage for good government work from old media, of course you reach out to influencers!

“Palmer accumulated nearly $10,000 in parking tickets on his red 2001 BMW convertible…and represented himself as homeless to qualify for a city program that forgave most of his fines, even though he lived in an apartment.” Chronic parking crimes are often the tip of a nasty iceberg.

If marginal tax increases were a slippery slope to authoritarian communism, wouldn’t it have happened by now? At least once? Many countries have had progressive taxation, business regulations, and welfare states for decades, yet not one went Soviet, or anything like it.

I think part of the pundit crack-up has been that they missed the big call of their lifetimes about which was the bigger threat to America: wokeness or authoritarianism. And rather than admitting that, they are doubling down on wokeness, while ignoring an authoritarianism that does not threaten them

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.
