Except that in SF you must bring your bicycle inside with you, which basically was only feasible for your office/workplace. Cannot do with a grocery store, theater, gym etc.
Edit: An idea that came to mind, someone run with this. Bike lockers would be an amazing feature that likely could curb a lot of the issues. Something with a secure lock built in (like biometric or complex pin), 360degree cameras, and an insurance policy. I'd have paid hourly for that service if I still lived in the city.
