> looks like they've excluded areas with more tourists If it's anything like NYC they did this to avoid upsetting the existing bike rental businesses in those areas. They need to do this to get local government buy-in of the program.

This is exactly the case. My understanding is that they've pitched themselves as a commuting solution to get approval, and the local tourist bike rental places complain as they get closer to the standard tourist biking areas of Golden Gate Park and the bridge.

Edit: The lack of bikeshare on 24th street is a separate issue with Calle 24, which could reasonably be called NIMBYism.

Sorry, nothing I can link to, just personal conversations with employees.
