The Wiggle is the most important piece of bike infrastructure in SF, and most of it is just sharrows. The worst part is the concrete-protected lane.

Golden Gate Park isn't located in a place where a better bike lane along it will contribute substantially to bike trips. Almost all the attractions are at the east end, which is accessed via the Wiggle and JFK Dr. Context matters.

So, find ways to create community around biking, because the social factors are more important than the infrastructural. When advocating for infrastructure, choose battles worth fighting; there can be important pieces that make a difference, but a lot of it is meh.

So, my alternate vision for advocacy is: Bikes are fun. Biking is a normal activity that anyone can do. Biking is not especially dangerous. The #1 predictor of whether someone rides a bike is whether their friends ride bikes.

And don't get me started on Hoboken. I'm from Morris County, NJ and anyone who brings it up has never been there.

People fetishize Paris, because it is a city that is literally designed for tourists. No other city has 3 miles of the Rue de Rivoli where they can run a bike lane along one of the most visited parks in the world. They also kicked all the poor people out to make space for the literal bourgeoise.

So, one point is that bike mode share is very context-specific, and what works in one city isn't necessarily portable. One thing that Amsterdam, Copenhagen, and NYC have in common is substantial waterways, and cities without them have much more difficulty making bikeways that are pleasant.

In San Francisco, there was a big spike in bike mode share that corresponded with a period that the city was under a court order to not build bike infra because of an impending lawsuit. When the injunction was lifted, a ton of infra got installed but mode share flattened and is now declining. Why?

(above elided for skeet length). Why do you think, by your graph, commute cycling doubled in Chicago between 2000 and 2009? Is it because an enormous amount of Amsterdam-style infrastructure got installed? Or are there other factors at play?

Barnes and Krizek (2005): "None of the known factors...can come close to explaining why people in some places are 10 or more times as likely to ride bikes as people in other places...attitudinal and possibly historical factors...dwarf the effects of the factors that planners...can control."
