Imagine if cities demanded the same of car manufacturers.
Lime and Forest are on their "last warning" if they don't fix "persistent problems" with rider behaviour and dangerous parking.
Council demands “urgent action” from Lime and Forest hire bike operators to “fix persistent problems”
Islington Council has threatened that e-bike hire companies Lime and Forest are on their “last warning” and face losing permission to operate in the borough unless they deal with the dangerous parking...

I remember rummaging through laundry bins to find my "least dirty clothes" to wear to the pub so that clean ones wouldn't reek of smoke.
I remember arguments about ending pubkic smoking. It was the right decision. Other supposedly controversial views will also come to be seen as norms in time.

I lived thru the end of public smoking. Early in my career I presented to city councils who were smoking, in front of audiences who were smoking.
Smoking in restaurants, airplanes, hospitals…
All of that seems insane now, but it was very controversial when we DID change it.
We CAN change things.

It’s crazy that people used to be able to just smoke cigarettes wherever they wanted

Yes. Why is AI creating art and music? THIS thread is what I need it to be helping to do. [cries in 'drafting guidance document']
so it's been 24 years since Minority Report and I still don't have the wall-sized interactive augmented reality screen so Steven Speilberg STILL gets to feature AR/VR interaction in a new movie like it's science fiction.
guess that means I won't have AR screens to write on 25 years from now either

Exciting road pricing news out of Denmark!
Today a new expert group for designing the future car taxation was announced, with a focus on the externalities from cars.
See the terms of reference below. I will soon follow up with a piece on why I think it actually can lead to GPS-based road pricing.

U can have a park for the people or park cars. The town of Tulln in Lower Austria made the choice for the people. They turned a concrete desert into a green paradise at the very heart of the city. We need more of these transformations. For families, seniors, teenagers…..
Park statt Parkplatz, Grünoase statt Asphaltwüste: In Tulln wurden mehr als 150 Parkplätze durch einen grünen Park für Menschen ersetzt. Ist viel schöner, verbessert Mikroklima und Lebensqualität. Nachahmenswert! #Klimakrise #Klimawandelanpassung

A good counter point to victim blaming rhetoric is noting that the best cyclists in the world get hit by drivers. It's not about skill; it's about lack of infrastructure and dangerous drivers (yes, even in the Netherlands). This happened in broad daylight too.

As winter flooding looms, it's worth noting that a young street tree in an asphalt surface can prevent 60% of the rain that falls on it from reaching the ground, even when not in leaf.
Increasing the low levels of urban tree cover should be a strategic national priority.

Again I am dying not to drive. I don’t want to drive. If you make spaces for all it gets people like me off the roads and less traffic for the people that want to drive.
Here’s something that’s really important for everyone to understand.
If we design our cities just for cars, they fail everyone, including drivers.
If we design our cities with many great CHOICES in how to get around, they work better for everyone, including drivers.
Spread the word.

A typical European car is parked 92% of the time. It spends 1/5th of its driving time looking for parking. Its 5 seats only move 1.5 people. 86% of its fuel never reaches the wheels, and most of the energy that does, moves the car, not the people.
