Driver: 30km/hr is way too slow for our roads!
Also driver: hey cyclist slow down you’re going 20km/hr - You could kill someone!
There is a lot of discussion lately about the rise of data centers. A reminder about the 2025 webinar series on “Is AI sustainable?” by Ohio State’s Center for Urban and Regional Analysis (CURA). I especially recommend the talk on local impacts of data centers by Julie Bolthouse:
Interventions such as cycle lanes, uptake of electric cars and restrictions on polluting vehicles helped to drive the improvements in air quality

Brilliant:
“Measuring deaths per mile lowers the ceiling on what even the best-crafted safety strategy can achieve. Yes, building less dangerous cars and more forgiving roads would help... But another way to save lives deserves far more attention than it gets: Stop forcing Americans to drive so much.”
“It seems insane that a place as flush with cash as this town can’t keep things like this that allow society to function.” 💯
At ~$1 billion/day, the US has spent as much on the war in Iran in ten days as the entire FY25 budget for the National Science Foundation ($10 billion).
Trump's FY26 budget request for the agency declined to $3.9 billion, due to a "realignment of resources in a constrained fiscal environment."
We already have an epidemic of cars hitting people and buildings, sometimes intentionally as weapons of terror. So explain to me how flying cars will work without TSA-level security to prevent someone from flying one of these into my house or my children's school.
The latest publication from the Ghost Neighborhoods project where we are generating 3D urban models from historical Sanborn fire insurance maps. These maps exist for 12,000 places across the USA for the period 1880s-1960s. Our techniques - including community engagement - can be applied widely
I am pleased to share the latest publication from the Ghost Neighborhoods of Columbus project where we are using machine learning and GIS to create 3D urban models from historical Sanborn fire insurance maps. These maps exist for 12,000 cities and towns across the USA for the period 1880s-1960s.
‘Once a country has the tools to harness the sun and the wind, the energy sources themselves cannot be taken away. “You can’t weaponize the sun. You can’t weaponize the wind.”’
Not only does this hurt the auto industry, it harms households, families and communities. Mobility does not need to be this expensive.
“The scarce resources we have should be used to prioritise the basic needs of people in poverty and to create what is of societal value rather than serve the frivolous desires of the ultra-rich.”
Old school
Pro-tip: carry currency when you bicycle. A bill can serve as an emergency tire repair. This bill got me 10 miles back home. Follow me for more life hacks!
I mean, if the argument is based on the 85th percentile rule than it is suspect
Yes, that is the traditional wisdom. Is it correct?
Are there any studies to support this? I know traffic engineers believe this, but traffic engineers believe a lot of things that vary from theory and evidence:
Sometimes lowering the speed limit might make roads more unsafe, not less, ODOT spokesperson McGuire said.
👉 “I would challenge anyone to find leftwing indoctrination” at Ohio State, said Danielle Fienberg, a junior and history major who took a Chase course last semester. “Professors want you to challenge them, they want you to disagree.” 👈
Most American "bike lanes" are little more than lines of paint at the edges of deadly roads — and that lack of protected infrastructure is keeping many would-be riders out of the saddle, a new study confirms.
