I’ve been a bicycle commuter for 25 years, primarily in the US (Minneapolis, Santa Fe, Bay Area) but also 3 years in London. Your last 3 points are much more important than the first three, there’s simply an attitude problem in the US, and it goes both ways, both drivers, and riders (and even pedestrians) are militant and angry about the space they feel entitled to. Compare to London where the streets were designed for neither automobiles nor bicycles. In London there’s a culture of acknowledgement that we all have to make do with the available space. So pedestrians spill into the street, cars occasionally have to go up onto the pavement (aka. Sidewalk) and bicycles achieving critical mass happens naturally during peak times. London is 10 times as congested as SF and yet everyone is 10 times as calm. It’s amazing to me the success the auto lobby had in America a century ago to create a culture where the default is that everyone should be able to drive super fast and have parking available in every square inch of developed land, and anyone who uses anyone who uses any other form of transportation is an uncivilized pleb deserving of second rate accommodations at best.
