My latest newsletter digs deeper into the San Francisco Fire Department's emergency response times to Slow Streets to understand why it took them 31 minutes to travel five blocks.

If you want to bring your 4 wheeled air conditioned living room into our city's flagship park you absolutely should have to goddamn pay to do so.

Yes, you should have to pay to park in Golden Gate Park
San Franciscans are used to a high standard when it comes to their parks. That’s about to change unless the department can scrape together funds, fast.

Anyone else struggling to focus & stay motivated with this weather and endless barrage of bad news?

I have several projects that are like 80-90% completed and can't seem to get them done.

How are y'all battling fatigue, despair and the feeling that nothing you're working on even matters anymore?

After 4 years & connecting 320 people in need with free bikes, Bike Match Network is shutting down.

Plus a deep dive into why Telraam's traffic monitoring sensors haven't been effective at calming our streets in the Bay Area.

New substack just dropped 🔥

New data analysis & op-ed:

Turning the Great Highway into a park will bring millions to local businesses AND will likely reduce vehicle crashes and emergency response times throughout the Sunset District.

Support our local businesses by voting #yesonk!

The city's walkers and rollers won't be the only beneficiaries of a permanent highway closure. Nearby businesses will see a spending windfall.
