June US transit data is in today, & all of the 10 largest US rail networks are growing! SF is seeing a real boom, with ridership up 16% on Muni & 14% on BART SEPTA (Philly, 9.1%) and PATH (NY/NJ, +8.7%) are also seeing strong growth, while MTS (San Diego, +1.4%) is the slowest🧵

“he was confronted by Trump over the bare weapons stockpile, Hegseth defended himself & blamed his deputy, Stephen Feinberg, for the shortages & for not ensuring Trump was fully apprised of the issue” Throwing underlinings under the bus for your own incompetence will go over well in the military.🙄

Trump, Hegseth clashed at Camp David over Iran missile depletion concerns

At a Camp David summit this weekend, President Trump demanded answers from Defense Secretary Pete Hegseth over extreme munitions shortages.

I want AVs to improve urban safety outcomes and mobility choices. But absence of basic data transparency and worsening public comms suggest Waymo hasn't learned from Dec 22 and July 4 debacles - and isn't ready to scale in cities. Read: thefrisc.com/waymo-behavi...

Waymo Behavior Now Harder to Decipher, Even After July 4th Fiasco

Mayor Lurie wants more scrutiny. Despite new California DMV rules, there’s less information publicly available, not more.

I have long wanted to write for the excellent Bay Area publishing collective COYOTE...and they let me write something that honestly no other publication would. All hail independent media!!

Early on @coyotemedia.org made a list of dream bylines we'd LOVE to have on the site and @annaleen.bsky.social was one of the first on it for me. So stoked to see this piece about ~~speculative transit~~ and big dreams for the Bay Area. www.coyotemedia.org/funding-bay-...

SF's high housing costs arise from three "separate policy failures: federal affordable housing defunding since the 1980s, exclusionary zoning with racist roots, and a permitting process that legislated NIMBYism. Picking one villain lets everyone else off the hook." missionlocal.org/2026/08/san-...

Who killed housing affordability in San Francisco?

Despite what the most vitriolic keyboard warriors on the internet would have you believe, this is a complicated question

I wrote about this NYC congestion pricing study earlier this year, noting that most driving time savings accrues to people who never venture into the zone at all (i.e., driving within Queens or Long Island). IOW some of the most vociferous critics of CP are among its biggest beneficiaries.

Congestion Pricing’s Unexpected Winners: Suburban Drivers

NYC’s controversial toll program hasn’t just sped up trips inside Manhattan, a new paper finds. It’s easing traffic in outer boroughs and neighboring counties.

In the 70s-80s Curtis Green and H. Welton Flynn reinvented Muni while other cities abandoned transit. Art Agnos staked his political future on demolishing the Embarcadero Fwy. I can't wait to hear more about these inspiring figures, esp @peterhartlaub.bsky.social interviewing Mayor Agnos himself
