"Waymo has told advocates that expecting it to respect bike lanes is 'too high a bar' because customers expect to be dropped off in them." To be crystal clear, it's illegal for a car to be in a bike lane. It doesn't matter what Waymo's customers expect; the company shouldn't be doing it.

Transportation historian Peter Norton doesn't buy into the robotaxi hullabaloo: "What robot cars are promising is the next generation of car dependency." In @bloomberg.com, my lengthy conversation with @norton.bsky.social

NEWS: A federal judge has saved the 15th Street protected bike lane (for now), saying the decision to remove the lane running from Constitution Avenue to the Tidal Basin was "arbitrary and capricious and not the result of reasoned decision-making." It was to be removed this week.

Would you be of any use if you came across a traffic crash with bleeding victims? Consider a www.stopthebleed.org course. There is almost certainly a free one close to you.

"They were so lucky I was looking" Ummm no. Stopping in time for a child running onto the street is not heroic/lucky, it is your goddamn obligation as a driver. Cost of entry. Kids are allowed to be unpredictable, you are not.

Mohsen Miladi, E. Owen Waygood, Marie-Soleil Cloutier, Bobin Wang, and Zeinab Ali Yas: “Forcing pedestrians to wait a long time is making them pay for the danger that cares are creating and is leading to behaviour that endangers many of them.”

Also, they should be able to both define and draw an unmarked crosswalk.

It's the Second Dumbing.

This is terrorism.

This is the correct take.

I got a small grant to do some of the research on attitudes and culture around speed and speeding that I've wanted to do for years. I'm looking for some test cases, or projects to align with in a complementary way that is useful to us both. Thanks! Please RT if you don't mind. 🙏

*Collaboration/information request!* If you are in any way involved in the CA speed camera pilot programs, or work on smart speed management with vehicles (design, engr, regulation, etc), or your work is focused some other way on speed/ing, please let me know!

Anyone know if “caution bus is turning” announcements have actually increased safety? My own anecdotal experience is that they just seem to make bus drivers more comfortable violating my right of way at crosswalks.

✨Schrödinger’s Crosswalk ✨, joint work with a terrific interdisciplinary team, under submission to law reviews now. It’s a bit unconventional (6,600 words, including a table, plus maps) but, we hope, appealing for the right journal.

WABA — who sued the feds over the planned removal of the 15th Street NW protected bike lane — says the Justice Department reports the project won't begin today as previously announced, but rather on or after March 30. Don't miss @maustermuhle.bsky.social's reporting on the bike lane brouhaha:

It’s a Sidewalk Palooza weekend!👟✨ Across DC, neighbors are walking, rolling, and auditing our sidewalks, identifying tripping hazards and pedestrian infrastructure issues, submitting 311s, and building more accessible public spaces. Find an event near you: sidewalkpalooza.org #SidewalkPalooza

Sign, share, show up Monday: waba.org/action-page/...

Book Announcement!!! Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource is available for preorder and out June 2 with @harvardpress.bsky.social! a.co/d/0d1DwIVc

Do you know how walking was turned into an opportunity for intrusive and discriminatory policing – and how advocates and policymakers in Kansas City have shown us the way to do better? www.kcur.org/history/2026...

It is really surprising how fear of liability stops transportation agencies from deviating from a dangerous standard. Time to learn about the legal tools we have to hold agencies accountable for the poor road safety outcomes they produce. Register: bit.ly/4aymktN

From last week

Good afternoon to everyone who drives who doesn't do the slow roll toward you while you're crossing.

Blame shifting as agenda advancement: how streets were redefined from places for everybody to high-speed motor thoroughfares. A story that begins in Kansas City. ... www.kcur.org/history/2026-01-29/kansas-city-jaywalking-crime-pedestrians-cars-right-of-way

Let's talk about #Rochester, NY (2023 pop. 207,274). Municipal sidewalk snow removal began there on 12 residential streets in 1905 and eventually expanded to the entire city, as per historian Blake McKelvey (p. 10). www.libraryweb.org/~rochhist/v2... #PlowSidewalksToo

It's hard to overstate how ell-organized the portland march that got gassed was... organizers made the crowd promise to be peaceful, said the march would slow in front of the ICE building but not stop, that we would stick to one chant (ICE Out). They did absolutely everything right and got gassed.

“Observing human behavior confirms that for some among us, the perfidious lust for unbridled power and the imposition of cruelty in its quest know no bounds and are bereft of human decency. And the rule of law be damned.”

Federal judge has ordered the release of Liam Ramos (the bunny hat boy) and his father. A brief and rather remarkable order. Clearly written to be shared widely, so please do. storage.courtlistener.com/recap/gov.us...

Pet Peeve: Saying that sidewalks are the responsibility of the property owner and not the city ignores the fact that it's *the city* that is ultimately responsible for enforcement. ...and if that accountability system doesn't work, then its *the city* that then is in charge of creating new system.

A standard of truth long since abandoned. Senator Howard Baker helped lead the investigation of a popular president of his own party, and in the end most Republicans in Congress joined him.

As a state that values walking and biking, we cannot allow the governor to gut the rights of the people most at risk — especially since it won't lower insurance rates anyway.

Some businesses will close today to protest Trump's immigration crackdowns. Others will donate proceeds to a nonprofit that advocates for immigrants.

Underrated difficulty of walking near big roads in winter: the plow piles are that much bigger. I've had trouble crossing various roads all week, but on the corner of Georgia and Colesville (each ~6 lanes) in Silver Spring, one plow pile is so tall, it's impossible to see oncoming traffic.

Does anyone have concrete (pun intended) knowledge of sidewalk conditions are like between Waterfront Metro and Arena stage?

This single article may contain the highest density of excellent quotes of any I've ever seen. I'm saving this to use in talks and class, for sure. So many of all the phenomena I've ever studied are encapsulated here, with characteristic Irish wit.

Can’t wait to see the first AI-generated MUTCD. Not sure it could get any worse for pedestrians though.

ICE is WHIPPING through my suburban neighborhoods — not uncommon to see them going 50 mph — race through red lights, veer across multiple lanes to get to off ramps, no blinkers. They’re going to hurt or kill someone (else)

"Unfortunately, District government itself gave Politico … plenty of reason to look first to the budget implications." I have been thinking all week that it is unfortunate that Council let the Mayor ignore—and then repealed—the provision requiring ATE revenue fund traffic safety measures.

Cyclists have stories too but I have yet to shoot a motorist for trying to kill me.

I have a question, and the answer may be very simple or very complicated. This is about the Fourth Amendment. There are things it is difficult if not impossible to do for road safety, because the law treats your vehicle as protected private space. Setting aside the pros & cons of that, I wondered

I guarantee you that every pedestrian crossing the street with legal right of way in a crosswalk has experience(s) every damn day with someone driving directly at them. And somehow we manage to see stupidity rather than malice. We may look at them with contempt but we don’t kill anyone.

This is about elections.
