Yes. We've spent 70 years of more systematically building a country where for most people, it's all but impossible to live without a car. NY, DC, Chicago, and a few other places it's practical, but in most of the US, most destinations are too far away to walk to, and for the few that are within an easy walk, it's become an odd choice to walk. People are completely habituated to using the car even when it would be easier and more pleasant to walk. Bicycling tends to be dangerous because not enough people do it. It's largely the domain of urban 20-somethings and well-heeled old men. Sixty years ago, schools had gigantic bike racks outside that could take hundreds of bicycles. I don't think they exist at all anymore. I watched this happen---the parents of my generation sent you into the world at a very young age. From about six years old on, we biked everywhere. It was almost automobile level of mobility. One on a bike, two on a bike, sometimes a third kid on the handlebars. But the missing-kids phenomenon (which was completely bogus) killed that off almost overnight. By the time I had kids, lots of young people were still not allowed to walk to the corner store or to school at 12 or 13, an age when my generation had been running free for six of seven years, mostly on bicycles. Most Americans today have been trained from birth to see cars as the only way to get around.
