My recent Palo Alto experience: driver left turns with me walking in the crosswalk, sees me and stops within a few feet. Then... *Puts her hands over her eyes and accelerates.* Blindly and with no steering wheel control.

On an extremely packed 38R Geary bus. Seems like there could be a better way to transport the 4000 people on this bus.

Spending my birthday canvassing for @valencia4actransit.bsky.social for AC Transit District 3. Stopped into a store to cool off, might get myself a birthday card.

I kind of want to buy an autonomous vehicle that can just deadhead around causing traffic and sometimes follow me around when I'm biking so drivers can't make unsafe passes.

OCTA is the agency that runs exactly 4 bus lines out of one of the largest and most expensive transit centers in California.

This quote is nuts. How do you know if you're succeeding in "deliver[ing] bus service every day" unless you measure it, look at the measurements, and fix problems? Like, y'all check the fuel gauge on buses before they depart, right?

I think trans people don't exclusively want cis people to not vote for democrats that are anti-trans. I think that trans people want cis people to raise almighty hell about it until every democrat is ten toes down on trans rights, rendering the issue moot.

Question for the chat: I noticed while driving across the bridge last night (Monday) that the barrier had not been moved since the weekend. Any info on how often or when the barrier is actually moved?

IMO these numbers are unbelievably low, but the real numbers would cause people to just dismiss the report. Scale of magnitude: the number of inbound BART commuters, in cars, would fill every lane of every freeway from the toll plaza to Richmond, Walnut Creek, and Castro Valley.

We nearly got Meta to put up major money towards dumbarton rail. Pretty clear that all the companies if possible would love to shift ongoing private shuttle funding to public transit ops even if the upfront investment has about a decade ROI.

Welp, I guess the state forests will stay stuck with 1950's-era mandates to produce merchantable wood products instead of, I don't know, dealing with climate change. And, stay stuck with no reliable funding.

If the Dem consultant class were just "following the polls" they'd be encouraging candidates to go hard against "ai," stop arming the Israeli regime and embrace impeachment. They are doing the opposite, and their targeting of trans people is, likewise, about their own twisted ideology and cruelty.

This Thursday, we're kicking off the ground game for the Regional Transit Measure, with events in each of the 5 counties. There are 50 days until the election. In that time, we need to convince Bay Area voters to invest in public transit! In San Francisco? Come rally and then talk to BART riders!

Close watchers of San Francisco Bay may have noticed that it's been higher than usual. I've kind of noticed this for the past month, but really took notice when the spring tides caused flooding that is odd for this time of year. The bay has been 6" higher than typical.

Sitting on the sofa uploading a week's worth of bike lane obstruction photos to @bikelaneuprising.bsky.social . I've developed the habit of taking a photo EVERY TIME it occurs, which takes away the question of whether I should bother or not.

Happened to ride by MM today on a recreational ride (bike lanes on California!). Parking lot, about 40 spots, is full. At least 6 bikes parked that I can see, 3 cargo, including this guy. 15% biking mode share. 4 walkers just went in as I write this.

In the spirit of scientific inquiry, I drove to Monterey Market along Hopkins today to do a bit of grocery shopping. A trip report, I suppose. Decades ago when I lived in El Cerrito and was a Berkeley grad student, MM was conveniently between the two. I was car-free and cycled everywhere.

This isn't so much crayoning as a grab bag of neighborhoods in SF that don't have good rail transit access and then someone connected the dots: "North Beach!", "Noe Valley!", "the outer Richmond!" I wouldn't say it's political genius, but I'm guessing the vagueness decreases knee-jerk NIMBYism.
