Homelessness is a somewhat broad category though. There's lots of people couch-surfing between friends and their car. They're also in a very different position from people who are sleeping rough.
I only experienced traditional rough sleeping homelessness once when my "house" (my van) was towed and I had to sleep in an hostile architecture bus stop bench that had ridges between each "seat" area. Otherwise, I was technically "homeless"/vanliving in SV from about 2010-2019.
van is a home if you have your stuff in it, live in it, and enjoy moving around, this does not make you homeless, sorry. is a home on wheels and can be very comfortable should you decide so.
