I started riding cargo bikes to work and errands. 50,000 miles later, I feel a little sorry for all the people who didn't do the same.

Highly recommend this thread for insight into how off the rails the @wutrain.bsky.social administration has gone. How are people supposed to reconcile the mayor’s emotional remarks at Louisa’s ceremony with this about face? These decisions have life and death consequences, damnit!

Avant / Après Rue Montera dans le 12ème arrondissement de Paris. La place de stationnement handicapé a été conservée, les autres ont été remplacé par des arbres tout juste plantés en début d'année, et qui démarre donc leur vie dans la rue par des canicules à répétition.

I haven’t used it yet & don’t know that it’s been around long enough for me to have a well-formed opinion on the whole system, but a nice aspect of the Veo scooters that I’m seeing around is that the seat is long enough for (what appears to be) comfortable and safe dinking. Lots of kids using them

The first conversation I ever had with City Councilor @wutrain.bsky.social was about biking in Boston. We were both waiting to pick up takeout sushi, and she had recently tried biking to work at City Hall. We shared how exposed you feel when a truck barrels by with only a line of paint between. 1x

Chris Osgood, that’s who’s going to fix this mess? Seriously? He’s a political creature who will bend to the political whim of the day. Maybe I’ve been gone too long to understand the current landscape, but I have trouble accepting this as the administration’s best response.

Very surprised to see that Mayor Wu spoke at the vigil. I’m not on the ground, and don’t mean to second guess anyone, but after what she’s put the community through over the past year I would have advocated for excluding her.

Dang, New Haven has built some very high quality separated bike infrastructure, with bioswales and bollards that will mess a vehicle up! I’m assuming this all happened under Doug Hausladen’s watch?

In New Haven for the @phnetwork.bsky.social conference and while walking off a Frank Pepe pie I came across this monster cycle track under construction on State St. It looks to be 10’ wide. Full-width street reconstruction is going to result in some kick ass infrastructure.

With every passing year in Colorado (coming up on 8 years), I follow Boston issues a little bit less. Today I realized how out of touch I am and how long frustration has been brewing there. Lots of folks and communities were involved in @wutrain.bsky.social’s success but 🧵

No city that truly values public space, and believes that beauty should permeate the public realm would allow this.
A new light pole in an old concrete sidewalk with a hack-job asphalt patch, with a tree bursting out of its too-small tree well in the background. A dockless bike share bike is parked in the middle of the too-narrow sidewalk which is such because of orange jersey barriers and tables from a private establishment encroaching on the public sidewalk. There’s a door-zone bike lane adjacent to cars parked cheaply on the street.
All of this across the street from the primary train station for a major US city.

Can someone back home explain to me what you think is going on here? What’s the consensus on why there’s been a backtrack from such a promising start? Seeing a dunk contest on one of my favorite people is incredibly depressing, but there’s obviously a lot of frustration.

Bike lanes make traffic worse. They're inconvenient for seniors and families.
They harm small businesses. Most are permanently installed, even though it's too cold to ride four months a year.
And yet, Mayor Wu has spent millions of your tax dollars on these bike lanes, despite strong community opposition.
