I think Microsoft's approach to everything is summed up by how every team name pointlessly has "-UsrGrp" stuck on the end, when a single line of code could hide this internal bit of gubbins from users

Much to parse here. First, it's part of Sketch's ongoing campaign "Poor British Motorist!" This was during the great motorway building boom. And do you know who profited from that boom? Transport minister Ernest Marples ...

This is amazing! A colleague found it in her cavity wall whilst doing some DIY. A newspaper article from the 1960s bemoaning the introduction of some 50mph speed limits. "Poor British Motorists" - some things never change, do they?!

This is a small detail that jumped out to me, because it reinforces the need to design infrastructure for the lowest common denominator, whether it's a child or someone using a mobility device. Infrastructure must work for everyone!

Smooth routes were found to be very important for some people, but not a major consideration for others. For those where it is the difference between a street being useable or not, then smooth routes are critical, as was the case for some older people and people who roll, exemplified by the ‘access is not optional’ viewpoint. One participant described the wheels on their wheelchair as like the wheels on a shopping trolley, “fine in the supermarket, but in the real-world pavements and roads are not that smooth.”.

Looking forward to seeing this expanded to also cover cars that have been left for more than two hours...

The British Transport Police (BTP) says it will not investigate bike thefts outside stations where the bicycle has been left for more than two hours.

Bike thefts at stations 'decriminalised'

Bike thefts at stations 'decriminalised'

The British Transport Police will not investigate many categories of bicycle theft, the BBC learns.

"The single most important behaviour, design or regulation for creating streets conducive to walking and cycling, was physical separation between the modes"

We've got a new study out, learning from a broad mixture of street users, planners and designers

www.sciencedirect.com/science/arti...

Highlights
For marginalised street users mode separation is the key to human-scale movement.
Streets conducive to walking and cycling have functional, safe and accessible design.
Professionals must approach street design, regulation and user behaviour holistically.
Combinations of influencing factors persuade people to either use or avoid a street.
There are no easy fixes to the public realm that will work for all non-drivers.

Will I be the first to suggest the carbon offsets worked exactly as planned: they delayed real action for another 25 years

The Guardian @theguardian.com · 1d

Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says

Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions The failure of carbon offsets to cut planet-heating pollution is “not due to a few bad apples”, a review paper has found, but down to deep-seated systemic problems that incremental change will not solve. Research over two decades has found “intractable” problems that have made carbon credits in most big programmes poor quality, according to the study. While the industry and diplomats have made efforts to improve the system, it found much-awaited rules agreed at a UN climate summit last year “did not substantially address the quality problem”.

Motorists will have to give way to cyclists on "Cycle Street" on Adams Road, Cambridge.

England’s first “Cycle Street” will give priority to cyclists and pedestrians over motorists

Work has started on Adams Road, Cambridge, to remove on-road parking, widen footpaths and redesign junctions to make walking and cycling safer

In non-LLM AI news, Waymo has quietly been involved in two fatal car crashes in 2025. Phil Koopman details that this fatality rate is now comparable to humans.

The Primary Energy Fallacy is the idea that all primary energy from fossil fuels must be replaced with equivalent amount of clean energy.

BUT: Not necessary because >2/3 of all primary energy is lost as waste heat.

Electrification+renewables are far more efficient.

Everyone needs to know about Hyden! A few police forces have been okay on this in the past, and have treated near-misses as serious opportunities to intervene. We need more

Interesting research on attitudes towards & use of e-cargo bikes in the UK.

Particularly noteworthy for demonstrating the level of interest in e-cargo bikes nationally and the extent to which they replace car journeys. In a trial in suburban areas over 50% of the distance travelled replaced car use

I guess, to try to be fair, the number at each grade is a fairly fixed multiple of the number at the next grade, so if you count the deaths you can basically know the minor injuries. Which has some advantages, as deaths are rarely unreported

Yeah, I typed that too quickly as my phone was ringing! But I think there's a lot more conflict built into a lot of cycle infra than there is for driving infra. The shared-use path I used this morning being a great example

Prof. Ian Walker @ianwalker.bsky.social · 5d

People will (not unfairly) point out there is possibly more than 265x driving than cycling. But a critical nuance is that drivers are never expected to make their trips in narrow shared spaces and roads full of conflict points

It's also missing the fact people were critiquing a focus on happiness and positivity long *before* the pandemic, e.g., www.waterstones.com/book/smile-o...
