SF’s fireworks show lasted 15 minutes. Traffic lasted all night
Fog hid the fireworks, but nothing hid the gridlock that stranded Waymos and delayed buses.

On Saturdays Haight Street gets chronically congested from private cars and unregulated car-based gig chauffeuring and delivery systems for elites. If you know me you've seen the pictures. Today. Nada. EB 80 Freeway closed. How it should always be. Quiet.

Yes. We need regime change. But we also need structural change. Including changing the capitalist car-system that violently sucks up the planet's resources and that under girds all of these wars and land grabs. And no, EVs are not the answer. They're just more of the same.

Despite the left in Paris being somewhat divided, the left of center socialist won. The maps, once again folks, reflect Paris' politics of mobility. Purple went socialist. That's bikey Paris. The Blue went for the right wing. That's the SUV crowd. Here in SF they drive Rivians (or are chauffeured).

Scenes from the Waymo meltdown during a long power outage in SF. It was dumber than dumb. When suburban car and gig drivers tried to leave at once it reminded us of how many cars are crammed into the city. 24 hours later City Hall still has no power. Time to revisit the Raker Act and municipalize.

SF has had relentless dense and cold tule fog for 3 weeks. The steady NE wind carrying the fog into the city smells like an oil refinery. It's especially noticeable on the south side of the bridge and in the Presidio. I also smell it every time I leave my apartment in the morning. Probably Chevron.
