New study by Mousely and colleagues illustrates how for most, “adolescence” persists until age 32.
Consider what adolescents are permitted to do in the U.S., often decades before we might consider them biological adults. 🤔

I suspect many of our northern friends and colleagues understand this simple truth:
snow, in less auto-dominated places would be a delight, magic to the young and old alike.
Instead, all we hear about is how this natural and otherwise wondrous occurrence foils car travel.

As @sgoodyear.bsky.social so eloquently conveys, dependence on a functioning car to satisfy the needs of life is the antithesis of ‘freedom.’
🚗💥 What if life after cars is better for everyone?
In LIFE AFTER CARS, @sgoodyear.bsky.social of @thewaroncars.bsky.social shows how communities can thrive when we design for people, not traffic.
A bold, hopeful vision for the future of our cities.

Fact. People perceive, appreciate, and use quality bike/ped/transit infrastructure.
Induced demand: it works for more than just cars
The latest evaluation of bike lane projects in Boston continues to show that if you build bike infrastructure, people will use it.

The end of daylight saving is 2nd only to New Years for the density of totally reasonable promises we make to ourselves
I'm sure the extra hour of sleep tonight is what it is going to take to get my shit together. I can't wait to wake up and start my new routine where I eat healthy, work out regularly, and keep up with all my emails.

Cars are often “structural killers”—they kill directly (via crashes + pollution) and indirectly (via facilitating drive by shootings or drug ODs in the wake of car crash injury).
Yet cars are frequently compared to “direct killers” like guns and opioids.
100% unfair.
