The bicycle could have been, and is in many cities (see Copenhagen or Amsterdam). The decision to include the automobile as "a staple of growth in modern society" is the reason it isn't a drop in fit. We designed our cities around dangerous, pollution producing power tools, and in doing so squashed out any hope of implementing something better. If you think about it, the only reason the bicycle isn't a safe alternati…
I agree that in a dense urban environment, the bicycle could be a much better fit for personal transportation. But as someone who has lived in smaller Midwestern cities, many more lives that some people care to think about depend on the automobile as a livelihood. Even in smaller metro areas, a bicycle would not be a viable option in the least. Cities like Copenhagen and Amsterdam precede automobiles by hundreds of y…
Now, we have a hundred years of data and experience with the automobile, and it's become obvious that the fossil fuel powered car isn't a good long-term solution to the urban and suburban transportation problem. Literally everything about them is bad for the world, gathering and burning the fuel, the destruction required for their roads, the massive amount of space needed to store them, and the death and destruction they cause daily. Electric (and other alternative fuel) cars are less bad, but only in one small way, they address a single issue in an inherently flawed model.
You say that Europe has an advantage because it's cities are much older, but it's important to understand that the Netherlands and Denmark were both on the same auto-centric trajectory that the US was on coming out of the World Wars and industrialization. Denmark only started rebuilding their cycling infrastructure after decades of disuse when the energy crisis in the 70s made using a car extremely expensive. In both countries, people realized just how bad cars were. The deaths of cyclists (especially children) sparked mass protests where people demanded cycling infrastructure, and they got it. They were able to convert a car-focused city (perhaps less so than Los Angeles or New York, but still) into a bike focused city. They were able to do it, why can't we?
