When I was in SF, the coworkers who drove in were those who lived outside of the city who were trying to save money and raise family. Buying a home in the city is impossible for these people (and me). Mostly less prestigious jobs, like cleaners, technicians, office managers. Not the App guys making 300k living in the Marina.
It's often an unintended tax on the poor.
IDK maybe there's some middle ground where we beef up public transport while beefing up parking at stations.
