SF has had relentless dense and cold tule fog for 3 weeks. The steady NE wind carrying the fog into the city smells like an oil refinery. It's especially noticeable on the south side of the bridge and in the Presidio. I also smell it every time I leave my apartment in the morning. Probably Chevron.

Mayor Daniel Lurie what are you really going to do about the violence of motorists in San Francisco? It is out of control. Cameras only catch them after the kill/injury of innocents. And no, the computers driving cars will kill too. My computer crashes all the time. I am sure yours does too.

In 2023 a friend sent me an update photo. So has the Vatican expelled the car?

In 2015 I visited the Vatican, partly inspired by Francis' encyclical that urged reducing car dependency and green mobility in cities - "On Care For Our Common Home." He was spot on then. But I was dismayed at the Vatican parking.

Based on the map, it appears the "yes to expand highways" vote was in a belt of Cantons surrounding Zurich. Zurich is the canton surrounded by green. Looks familiar.
