This is incredibly common in SF. Many people live in co-ops and it’s created an entire subculture where they coordinate large parties and events both within the co-op and with other co-ops. It’s gone beyond necessity and become preferred by some because they enjoy living with lots of others. Not my thing, but many friends live in co-ops and love it.

The psychology behind prices surrounding cars is outright evil. You don’t even notice how much you spend on them because everything is auto-deducted from your accounts (insurance, registration, etc.), gas is death by a thousand cuts, and repairs are seen as a necessity because it’s your transportation.

I’m well aware I’m saving money by not having a car. However, spending $40 on bike maintenance every few months feels so much more expensive than $400 on a car, even though the bike is my transportation.
