In the 1950s people walked to work, to get groceries, to the movies, to the hardware store etc., cars were almost not needed in cities (except delivery trucks). Imagine how nice it would be to get off work, walk 10 minutes to get groceries, another 10 minutes are you are home with all your shopping. Then walk 10 minutes in the evening to the library or bar. This is what people want again. It was lost when we created car-centric suburbs in the 1950s as part of a large post-war housing boom.
