So last night a driver was ticketed for parking in a red zone in front of my house.
This morning, the front of my house is covered in motor oil.
Incredibly anti-social behavior.

Housing is expensive because we have a shortage. Wall Street is investing in housing *because* the shortage is structural.

Other electeds in the Bay Area take transit. And security could certainly board Muni, or walk/bike alongside the Mayor if security is the concern.

Widespread adoption of AVs means *more* cars on our streets, not fewer. Safer, rule-following cars, but still cars.
Higher net VMT means more demand for travel lanes. AVs will make it even harder to win dedicated space for transit and bikes.

The cost of collecting fares via Clipper in the Bay Area is $46mil/yr
