Less than 1 mile from my house there is an elementary school and none of the children walk or ride a bicycle to the school. 100% arrive in their parents cars or in a school bus. The reason is that it is not safe with roads having no shoulders or sidewalks and motorists driving faster than the speed limit and often paying more attention to their phone texts than to the road in front of them. The same applies to the high schools that depend on autos and buses to take students from home to school and back again.
Most housing project developers are allowed to have streets with no sidewalks due to corrupt or incompetent city officials. Public roads are used to provide parking of cars for hours and even for days or weeks and this eliminates safe places for bicyclists to travel. More than 50% of American cities are devoted 100% to owners of automobiles and this is a taxpayer subsidy.
In Europe and China there is the notion that government exists to serve the people. In the USA there is the firm belief (going back to the founding fathers) that government is meant to support the wealthy people and protect them from those in the working class or people who oppose the theft of their lands.
There is the concept of the public commons that belong to everyone equally. Privatization results in the commons being taken over by the rich and this is the same for public streets as it is with public airwaves and with public lands. A bicyclist is considered a parasite compared to someone who supports industry with the purchase of an automobile and the realization that the motorist is taking up public space and polluting the common air that others must breathe does not considered.
In Paris the mayor has been closing streets to auto and truck traffic and is creating living spaces for the working class people with grass and trees and benches and other amenities that have historically been accessible only to the wealthiest individuals and their families. In this case it is a belief in democracy that is the driving force which would never fly in the USA.
