It also won’t happen because not all of us live in cities. The “fuck cars” crowd never has any solutions for rural locations other than “don’t live there” as if rural areas serve no purpose. As long as farms are a thing there will be people out here, either farming themselves or supporting farmers,and things like scooters and trains either won’t work or only partially solve the problem.
Anyone who thinks getting rid of cars is a viable strategy in the US of all places is delusional.
