✅ Low-car city-centre streets ✅ Protected cycle tracks on main roads ✅ Ample cycle parking at shops and huge underground bike parking at the station = Streets safe enough for families to cycle, quieter neighbourhoods for residents and more welcoming cities for visitors. 📍 Delft, the Netherlands

Eerste van der Helststraat, Amsterdam in 1978 and today
Then-and-now comparison of Eerste van der Helststraat in Amsterdam. Top, 1978, black and white: a street jammed with cars, including a van, an Opel estate and a saloon, parked and queuing both sides. A cyclist threads between the traffic in the middle distance. 

Bottom, today, in colour: the same street, now a tree-lined pedestrian zone with no cars at all. Tall leafy trees arch over the brick paving, and the street is busy with people walking, including a family with children, past café terraces and market stalls under the shopfronts.

Just did some number crunching using latest (Oct 1) ECMWF seasonal data, and I must say that I've never seen such high predictive confidence in a very wet California winter. This is a truly extraordinary forecast amid a record-strength El Niño event. [Thread: please read to end.]

Awesome new paper by @ashtonindc.bsky.social unpacking ideas about "what—and who—our streets are for" that are behind car supremacy. By analyzing what people say at public meetings, this paper makes the case that individuals are upholding car supremacy and stymieing efforts to build safe streets.
"Car supremacy: Deconstructing the ideology driving our modal hierarchy" by Ashton Rohmer.

Abstract: Cars have shaped modern life in profound ways, from restructuring our built environment to altering our notions of success. They have also had a variety of negative impacts—neighborhood destruction, resource wars, ill health, and environmental damage to name a few—which are largely normalized in our collective psyches. Existing theories of the rise of the automobile are focused on macro-forces such as a globalizing political economy; while important, these fail to explain how local transportation policy has been leveraged by members of the general public to perpetuate an unjust system of automobility. This article argues that our existing beliefs about who has a right to exist in our public rights of way are socially constructed through an ideology of car supremacy. This ideology is used by private citizens in public meetings to prevent our streets from being safe, accessible, and equitable for all road users. Using existing literature and a critical discourse analysis of empirical data gathered from local public meetings, this article defines the core convictions of the ideology of car supremacy—moto monoculture, auto impunity, and modal marginalization—and demonstrates how individuals enact it in public discourse through three rhetorical devices—static scarcity, blame inversion, and nefarious minority—to create a modal hierarchy that marginalizes non-car users. Moreover, this article suggests how urban planners and policy makers can cultivate civic engagement practices that curtail the harmful system of power perpetuated by the ideology of car supremacy.

Oudezijds Voorburgwal, Amsterdam in 1980 and today
A before-and-after comparison of Oudezijds Voorburgwal, Amsterdam. The top image, in black and white and dating from 1980, shows an open cobblestone square used as an informal car park in front of a large bare brick wall with scaffolding. The bottom colour image shows the same location today: the car park has been transformed into a lively pedestrianised square with outdoor café seating filled with people, young trees, ornate street lamps, and decorative tiles mounted on the now-restored brick wall. A cyclist passes on the left.

It doesn’t need to be complicated. Give buses their own space and signals, and keep families on bikes or scooters separate. Safer for them, and buses can keep to schedule.
