Comparing Seattle to San Francisco is disingenuous. Seattle has bike paths that don’t compete with cars. It also has the University of Washington, the largest University on the West Coast with over 50,000 students and staff. Biking for students makes a lot of sense.
San Francisco on the other hand has hills where biking is impossible or at least incredibly dangerous. The density of S.F. Is a problem. All the bike messengers I have known over the years have been in multiple car accidents. Biking makes sense for young tech bros commuting from SOMA to downtown, but doesn’t make sense for older people, families, and people living in the Sunset. S.F. Biking has never been safe, and no amount of ‘slow streets’ will make it so.
There needs to be a ‘yes and…’ approach to transportation. Yes, cars, and buses, and bikes, and self-driving vehicles. If we eliminate cars from S.F. As we have seen in recent years, workers and families will move to the East Bay, and commute in. While the young rich techies will ride their bikes to work. At this point, since the pandemic, there are much fewer businesses in S.F. Because people just don’t commute from the surrounding areas. If you prioritize bikes, people just won’t come into the city anymore making urban sprawl worse. You can see the prioritization of bike’s effects on the Academy of Sciences and the de Young. Much fewer people are going to these museums now even though there is underground parking adjacent to the buildings.
