There is a growing community of van dwellers/RVers who are living FT in their vehicles. CA is systematically outlawing these vehicles on streets overnight.
It seems they would rather have people living in tents and p00ping on the sidewalk than living in self-contained vehicles which can be moved far away when the owner chooses.
We know of construction workers who live in North Idaho who commute to the Bay Area for work and live in RVs while here. We also know of Paramedics who live in Utah and commute to the Bay Area for night shift work and live in an RV up on Skyline Drive during the day.
It seems like this is a growing phenomena and is the only way to get people here who aren’t paid exorbitant tech salaries.
