The Woman Who Saved San Francisco’s Cable Cars
City Hall called them costly relics and planned to replace them with buses. Friedel Klussmann turned a piece of Victorian machinery into a public cause—and gave San Francisco the power to keep its past moving.
Hayden AI
This video profiles Hayden AI, a company building an AI-powered platform that automates the enforcement of bus lanes on public transit systems. Cameras mounted behind a bus windshield feed an onboard compute box that detects when a parked or stopped vehicle is illegally blocking a bus lane. The system processes footage on the bus itself, blurring license plates and faces and transmitting only the clip tied to an actual violation to the cloud. Framed as a low-cost path to smarter cities, Hayden AI argues that one blocked bus lane impedes 50 to 60 riders at once, and that automating enforcement reduces collisions, improves on-time arrivals, lowers greenhouse gas emissions, and grows ridership.
